Description
RELATED APPLICATIONS
[0001] This non-provisional patent application is a divisional
application of currently pending U.S. patent application Ser. No.
13/970,100 filed on Aug. 19, 2013 and titled ORTHODONTIC BRACKET by
the same inventors, namely Paul L. Damon and Dwight H. Damon, both
individuals and US residents. The entire contents of the
aforementioned U.S. patent application Ser. No. 13/970,100 is
expressly incorporated herein by this reference.
TECHNICAL FIELD
[0002] The present invention relates to an orthodontic bracket, and
more specifically to an orthodontic bracket which defines a
transversely disposed arch wire slot which is selectively
adjustable so as to provide a variable cross-sectional dimension,
and which further provides a multiplicity of selective torque
expressions which individually forcibly act upon a patient's
tooth.
BACKGROUND OF THE INVENTION
[0003] In our earlier U.S. patent application Ser. No. 13/970,100,
and which was filed on Aug. 19, 2013, we described an orthodontic
bracket which when used in combination with an arch wire provides
first, second, and third orders of movement of the patient's tooth
without a clinically predetermined manipulation of the arch wire
which is received in the transversely disposed arch wire slot. The
various forms of the invention as disclosed in this pending US
Patent Application provides a multitude of patient and clinical
advantages not possible in orthodontic appliances which have been
utilized heretofore. The teachings of this prior co-pending patent
application are incorporated by reference herein.
[0004] Generally speaking, first order movements are commonly
thought of as tooth rotation, and in/out tooth control. Further,
second order movements are often referred to as "tipping" the root
in a mesial and/or distal angulation or elevation, and/or
depression of a tooth position. Further, third order movement, or
"couples," have resulted in the expression of "torque" which causes
the axial inclination of a tooth from a flared or uprighted
orientation to its final and desired position.
[0005] From its earliest utilization, and to achieve ideal tooth
positioning, a clinician has, heretofore, been required to bend
round and rectangular shaped arch wires to express the in/out,
up/down, tipping, and torque to accomplish a final, desired tooth
position. This activity not only took long periods of time, and
advanced clinical practice skills, but it was nearly impossible for
most clinicians to control the resulting treatment forces applied
in all planes of space. As a result, treatment times for patients
were often unduly long in duration, and the resulting treatment
forces which were applied often had a negative long term impact on
the patient's bone and tissue.
[0006] In 1970, Dr. Larry Andrews invented what was later termed a
"straight wire" appliance. This bracket design allowed significant
improvements to first and second order movements, and lessened the
need for the predetermined bending of the arch wires. However, this
design still lacked adequate third order control of tooth axial
inclination. The term "straight wire orthodontics" misled many
clinicians to believe that only one bracket torque prescription on
each anterior tooth was adequate to express a final desired tooth
position. Unfortunately, without bending rectangular arch wires to
individualize finishing torque on individual teeth, this had nearly
the same effect as treating patients using only round wires in the
bracket arch wire slot. This, of course, negated any third order
control. For example, if a 0.019 inch.times.0.025 inch stainless
steel rectangular working or finishing arch wire is placed in a
0.022 inch arch wire slot, there is approximately 11 to 12 degrees
of play, or freedom of movement, in either direction, for a total
of 22 to 24 degrees of play or movement before a third order
"torquing couple" is achieved between two opposite corners of the
rectangular shaped arch wire, and the opposing walls of the bracket
arch wire slot. Over the years, some clinicians have tried to fill
the arch wire slot with larger cross-sectional rectangular arch
wires to achieve third order control, but many have found it
difficult to finally position teeth due to the binding, and
friction which is experienced in the arch wire-bracket interface.
The use of these larger dimensioned finishing rectangular arch
wires in most clinical settings resulted in the application of
unfavorable physical forces, in both magnitude, and direction which
made final tooth positioning far more challenging for the
clinician. This also resulted in potentially negative, long term
impact on the patient's bone and tissue. For this reason, most
clinicians have tried to bend the appropriate amount of torquing
couple into the smaller dimensioned rectangular arch wires so as to
correctly procline or upright the axial inclination of the teeth to
their final desired position. It should be readily apparent that
the multitude of variations which may impact the third order tooth
movements are many, and consequently, orthodontists typically are
not readily able, in most clinical settings, to rapidly, and
accurately calculate the amount of third order couple that is
needed, and the appropriate amount of force that should be applied
to a given tooth to achieve the desired amount of tooth movement.
Consequently, because of clinician miscalculation, treatment times
for any given patient are often extended as individual clinician's
strive to achieve the desired tooth position, and alignment which
is appropriate. Additionally, it will be recognized that this
miscalculation of the appropriate amount of force to express third
order torque may result in excessive discomfort to the patient, and
as previously mentioned, potentially negative long term potential
health issues may arise for the orthodontically treated
patient.
[0007] While the numerous advantages to be achieved by utilizing
the various forms of the orthodontic bracket as seen in our earlier
filed application Ser. No. 13/745,638 are many, an ongoing need
remains for the development of an orthodontic bracket which is
readily and easily utilized by the clinician, in a clinical
setting, and which further provides a rapid means for adjusting the
orthodontic bracket in order to achieve assorted first, second and
third order movements of a patient's tooth in a manner not possible
heretofore. A new orthodontic bracket which achieves these
objectives is the subject matter of the present application.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0049] This disclosure of the invention is submitted in furtherance
of the constitutional purposes of the U.S. Patent Laws "to promote
the progress of science and useful arts" (Article 1, Section
8).
[0050] The present invention, in its various forms, is generally
indicated by the numeral 10 in FIG. 1 and following. For purposes
of the present application, and for the several forms of the
invention as described, hereinafter, it will be understood that the
various forms of the invention are employed to be releasably
affixed to a patient's tooth 11 as seen in FIG. 1A, and in
particular, to the anterior facing surface 12 thereof. The
orthodontic bracket 10, in its various forms, and in combination
with the arch wire as will be described, hereinafter, is employed
to provide a multiplicity of selective torque expressions which
individually forcibly act upon the patient's tooth 11. For purposes
of this patent application, the term "torque expression" as used
hereinafter, is defined as the force which provides rotation of a
patient's tooth 11 around the X axis 13, that being the
mesial/distal direction. In particular, the orthodontic bracket 10
of the present invention can be employed to achieve first, second
and third order movements, that is 13, 14 and 15, respectively, as
seen in FIG. 1A, without a clinically predetermined manipulation,
bending, twisting, or other rotation of the rectangularly shaped
arch wire, or the often repeated replacement of this same arch wire
during the orthodontic treatment period. Further, and as will be
discussed later in the application, the treatment of a patient may
proceed to completion without the removal of a bracket base 21, as
will be described, from the patient's tooth 11, although the
bracket body which is releasably mounted on the bracket base 21 may
be replaced with other bracket bodies during the treatment period
based upon the clinical judgment of the treating clinician. The
present invention 10 provides a novel means by which a clinician,
by utilizing a bracket body insert, as will be described
hereinafter, can readily adjust the cross-sectional dimension of an
arch wire slot as will be described to achieve first 13, second 14,
and third 15 order movements of the tooth 11 of a patient and
thereby considerably shorten patient treatment times, and also
achieve superior treatment results, and increase a patient's
comfort in a manner not possible by utilizing the prior art
appliances or practices which are known.
First Form of the Invention
[0051] As earlier discussed in this application, tooth movement is
defined relative to three planes in space. In this regard,
movements in these respective planes are categorized as first
order, second order, and third order movements, that being, 13, 14
and 15, respectively as seen in FIG. 1A. First order movements 13
are commonly thought of as rotation and/or in and out movements.
This refers to movements that can be viewed from the occlusal
perspective. On the other hand, second order movements are often
referred to as tipping, and can be viewed from a buccolingual or
labiolingual perspective. These include movements in the
occlusal-gingival direction or tipping about the buccolingual or
labiolingual axis. As a general matter, rotation about the
aforementioned axes would typically result in tipping of the root
or crown of a patient's tooth 11 in a mesial or distal direction.
These second order movements are used for paralleling of the roots
of the respective teeth 11 as well as elevating or depressing a
given tooth. Finally, third order movements 15, and which are
commonly thought of as "torque" can be viewed from a mesial-distal
perspective or a buccolingual cross-section. Third order movements
15 typically refer to movements about the mesial-distal axis. This
particular movement is often important when attempting to achieve
proper incisor or labia-lingual or bucco-lingual inclination.
First, second, and third order movements, again, are best seen in
FIG. 1A, and are indicated by the numerals 13, 14 and 15,
respectively. The first form of the invention is generally
indicated by the numeral 20 in FIGS. 1-6. In this regard, the first
form of the invention 20 includes a bracket base which is generally
indicated by the numeral 21, and which further includes a pad 22.
The pad 22 is suitably affixed by an adhesive, not shown, to the
anterior facing surface 12 of the patient's tooth 11. The bracket
base further has a peripheral edge 23, and further is defined by an
anterior or outside facing surface 24, and an opposite, posterior
facing surface 25 which is attached by the adhesive, not shown, to
the anterior facing surface 12 of the patient's tooth 11. As noted
earlier, this bracket base typically remains secured to the
patient's tooth 11 throughout treatment.
[0052] Referring now to FIG. 5, the first form of the invention 20,
and more specifically the anterior facing surface 24 of the bracket
base 21 includes a coupling portion or region which is generally
indicated by the numeral 30. The coupling portion or region 30 is
defined, in part, by a curved dove tailed shaped slot 31 which is
illustrated in FIG. 5 as being substantially concavely shaped.
However, and while the form of the invention, as illustrated, shows
a concavely shaped dove tailed slot, it is equally feasible that a
form of the invention may be fabricated whereby the curved dove
tailed shaped slot 31 assumes a convexly curved shape. Therefore,
the invention should not be limited to that which is illustrated.
It will be recognized therefore, that a curved dove tail shaped
slot, either of a convex or concave shape, may be equally employed
in the fabrication of the present invention. The described coupling
portion renders the bracket base, a "universal" base for use with a
multiplicity of bracket bodies, as will be described, hereinafter.
In the arrangement as described, the bracket base 21 can be
employed with bracket bodies which are considered passive ligation
types, active ligation types or conventionally tied brackets. In
view of this feature, a clinician no longer has to remove the
bracket base when removing and replacing orthodontic brackets.
Rather, a clinician must only remove the bracket body 40 from the
coupling portion 30, and reattach an alternative bracket body 40.
The bracket base 21 can stay on the tooth 11 for the entire
orthodontic treatment time. This feature greatly advances
orthodontic practice and makes an orthodontic treatment regimen
much more comfortable for a patient. The curved dove tailed slot 31
is defined, in part, by spaced sidewalls 32. Additionally, the
coupling portion 30 is defined, in part, by a centrally located,
and elevated region 33 having opposite sides, here identified as
33A and 33B, respectively, and which are located on the opposite
sides of the curved dove tailed shaped slot 31. The centrally
elevated regions 33A and B respectively each have a curved upwardly
facing surface 34 having the same curvature as that of the curved
dove tailed shaped slot 31. Each of the centrally elevated regions
33 include inwardly extending flange portions 35 which provide a
means for slidably, and matingly capturing and cooperating with a
movable bracket body 40 as will be discussed in greater detail,
hereinafter. Additionally, and formed in each of the centrally
elevated regions 33, and extending downwardly through the curved
upwardly facing surface 34 is a multiplicity of engagement regions
which are generally indicated by the numeral 36. The engagement
regions 36 are utilized to receive, and cooperate with a bracket
body insert as will be described in greater detail in the
paragraphs which follow. It will be noted from studying FIG. 5 that
the multiplicity of engagement regions 36 are disposed in a
predetermined spacial pattern which provides a convenient means for
adjustably positioning the rotatable orientation of a bracket body
40 and which will also be discussed below.
[0053] The orthodontic bracket 20 as illustrated in FIGS. 1-6 has a
movable bracket body 40 which is borne on the bracket base 21. In
this regard, the bracket body 40 has a main body 41 which is
defined, in part, by an anterior facing surface 42, and an
opposite, posterior facing surface 43. Still further, the bracket
body 40 is defined by opposite first (mesial) and second (distal)
sides 44 and 45, respectively, and which are located at a
predetermined distance, one relative to the other. Yet further, the
bracket body 40 includes a superior facing surface 46, and an
opposite, inferior facing surface 47. The superior and inferior
facing surfaces 46 and 47 define respective tie wings which are
well known in the art. As seen in FIG. 1-2, the bracket body 40
mounts a movable gate which is generally indicated by the numeral
50, and which is also well known in the art. The movable gate 50 is
operable to reciprocally travel or move along a path of travel 51
between a first, down or open position 52, and a second up, or
occluding position 53 (as seen in FIG. 1). The gate 50, which
movably cooperates with the anterior facing surface 42 of the
bracket body 40, is operable to selectively retain an arch wire as
will be discussed, below, within a transversely disposed arch wire
slot which is generally indicated by the numeral 60. The
transversely disposed arch wire slot 60 has a given volume, and
further has a first end 61 which is located adjacent to the first,
mesial side 44 of the bracket body 40, and an opposite, second or
distal end 62 which is located adjacent to the second side 45. The
arch wire slot 60 is defined, at least in part, by a top, or
superior surface 63, and an opposite, bottom or inferior facing
surface 64. The top and bottom surfaces which define, in part, the
arch wire slot 60 are disposed in substantially parallel, spaced
relation one relative to the other. The given distance allows the
arch wire slot 60 to receive an arch wire as will be described,
hereinafter. Still further, the main body 41 defines a supporting
rear wall 65 (FIG. 2) which extends between the top and bottom
surfaces 63 and 64, but which does not define the resulting arch
wire slot 60, as more fully described, below. The arch wire slot 60
has a central region or portion which is indicated by the numeral
66. The arch wire slot 60 is movable in both the vertical and
horizontal planes as will be described, below. This rotation of the
arch wire slot 60 in either of the vertical or horizontal planes is
maintained about the central region 66 of the arch wire slot 60.
This feature of the invention provides benefits and advantages to a
clinician who is employing the invention. In the arrangement as
seen in the drawings, it should be understood that the arch wire
slot 60 as more fully described below, has a predetermined
cross-sectional dimension which is variable by means of a bracket
body insert as will be discussed in greater detail, hereinafter,
and which fills or occupies at least a portion of the volume of the
arch wire slot 60.
[0054] The orthodontic bracket 20 as illustrated in FIGS. 1-6 has a
movable bracket body 40 which is borne on the bracket base 21. In
this regard, the bracket body 40 has a main body 41 which is
defined, in part, by an anterior facing surface 42, and an
opposite, posterior facing surface 43. Still further, the bracket
body 40 is defined by opposite first (mesial) and second (distal)
sides 44 and 45, respectively, and which are located at a
predetermined distance, one relative to the other. Yet further, the
bracket body 40 includes a superior facing surface 46, and an
opposite, inferior facing surface 47. The superior and inferior
facing surfaces 46 and 47 define respective tie wings which are
well known in the art. As seen in FIG. 1-6, the bracket body 40
mounts a movable gate which is generally indicated by the numeral
50, and which is also well known in the art. The movable gate 50 is
operable to reciprocally travel or move along a path of travel 51
between a first, down or open position 52, and a second up, or
occluding position 53 (as seen in FIG. 1). The gate 50, which
movably cooperates with the anterior facing surface 42 of the
bracket body 40, is operable to selectively retain an arch wire as
will be discussed, below, within a transversely disposed arch wire
slot which is generally indicated by the numeral 60. The
transversely disposed arch wire slot 60 has a first end 61 which is
located adjacent to the first, mesial side 44 of the bracket body
40, and an opposite, second or distal end 62 adjacent to the second
side 45. The arch wire slot 60 is defined, at least in part, by a
top, or superior surface 63, and an opposite, bottom or inferior
facing surface 64. The top and bottom surfaces which define, in
part, the arch wire slot 60 are disposed in substantially
parallel,spaced relation one relative to the other. The given
distance allows the arch wire slot 60 to receive an arch wire as
will be described, hereinafter. Still further, the main body 41
defines a supporting wall 65 (FIG. 2) which extends between the top
and bottom surfaces 63 and 64, but which does not define the
resulting arch wire slot 60, as more fully described, below. The
arch wire slot 60 has a central region or portion which is
indicated by the numeral 65. The arch wire slot 60 is movable in
both the vertical and horizontal planes as will be described,
below. This rotation of the arch wire slot in either of the
vertical or horizontal planes is maintained about the central
region 66 of the arch wire slot 60. This feature of the invention
provides huge benefits and advantages to a clinician who is
employing the invention. In the arrangement as seen in the
drawings, it should be understood that the arch wire slot 60 as
more fully described below, has a predetermined cross-sectional
dimension which is variable by means of a bracket body insert as
will be discussed in greater detail, hereinafter, and which
achieves the numerous benefits as earlier discussed in this
application.
[0055] As illustrated in the drawings, the orthodontic bracket 10,
and in particular, the first form of the invention 20, receives an
arch wire 90 which is received within the arch wire slot 60. The
arch wire 90 is of traditional design, and is further defined by
opposite top and bottom surfaces 91 and 92, and sidewalls 93 which
connect the top and bottom surfaces together, and which form a
substantially rectangular cross-section. In the arrangement as seen
in the drawings, the arch wire 90 is received within the
transversely disposed arch wire slot 60, and the bracket body 40
acting in combination with the arch wire 90, is adjustable in both
the horizontal or vertical planes so as to provide a multiplicity
of selective torque expressions 13-15, respectively, and which
individually forcibly act upon the patient's tooth 11. The present
invention 20 includes a bracket body insert 100, and which is best
seen by reference to FIG. 6, and which is received in the arch wire
slot 60 before the arch wire 90 is received in the arch wire slot
60. The bracket body insert 100 has a first end 101, and an
opposite second end 102. The bracket body insert 100 further has an
elongated main body 103 which is defined by a top or superior
facing surface 104, and an opposite, bottom, or inferior facing
surface 105. Still further, the main body 103 is additionally
defined by an anterior facing surface 106 which forms a supporting
rear wall 65 for the resulting arch wire slot 60, and an opposite,
posterior facing surface 107 which rests in juxtaposed resting
relation relative to the supporting wall 65, and which is defined
by the bracket body 40. The bracket body insert 100 has a height
dimension as measured between the top and bottom surfaces 104 and
105 which is less than the distance as measured between the top and
bottom surfaces 63 and 64, and which occupies a portion of the
volume of the arch wire slot 60 and forms, in part, the resulting
arch wire slot 60 which receives the arch wire 90. The height
dimension of the main body 103 allows the main body 103 to be
received within, the arch wire slot 60, and further rest in mating
receipt thereagainst the supporting rear wall 65 which is formed by
the bracket body 40. It should be understood that the main body 103
of the bracket body insert 100 may have a substantially constant
thickness dimension as measured between the anterior and posterior
facing surfaces 106, and 107, or may further have a variable
dimension. As such, the bracket body insert 100 provides a
convenient means for selectively adjusting the resulting
cross-sectional dimension of the arch wire slot 60 so as to provide
the benefits of the present invention which include, among others,
providing an orthodontic bracket 10 which provides first, second,
and third order movements for a patient's tooth 11 without a
clinically predetermined manipulation of the arch wire 90 which is
received in transversely disposed arch wire slot 60.
[0056] The bracket body insert 100 further includes first and
second engagement portions 111 and 112, respectively, and which are
located at the first and second ends 101 and 102 of the bracket
body insert 100. In particular, the first and second engagement
portions 111 and 112 extend outwardly beyond of the first and
second sides 44 and 45 of the bracket body 40, and further provide
a convenient means by which a clinician (not shown) may easily,
visually identify the bracket body insert 100 such that it may be
positioned appropriately or otherwise adjusted as will be discussed
in further detail, below. Each of the engagement portions 111 and
112 respectively, have an outside facing surface 113 which has
formed therein a depression or cavity 114 which allows a clinician
to insert a tool like tweezers or the like in the depression in
order to conveniently remove the bracket body insert 100 from the
arch wire slot 60. As will be seen in FIG. 6, the bracket body
insert 100 also includes a first, engagement member 115 which
extends normally, downwardly relative to the first end 101 of the
bracket body. The first engagement member is dimensioned so as to
be slidably received within a first passageway 71 which is formed
in the first side 44 of the bracket body 40. Still further, the
bracket body insert 100 includes a second engagement member 116,
which is shorter in length than the first engagement member 115,
and which further is received in a second passageway 72, and which
is formed in the second side 45 of the bracket body 40. The first
engagement member 115 has a distal end 117 which is operable to be
matingly received within one of the multiplicity of engagement
regions 36 which are formed in the bracket base 21. As will be
recognized, when the main body 103 of the bracket body insert 100
is appropriately inserted within the arch wire slot 60, the distal
end 117 of the engagement member 115 is received within one of the
multiplicity of engagement regions 36, and thereby is effective in
fixedly, rotatably positioning the bracket body 40 in an
appropriate rotatable orientation relative to the bracket base 21.
Further, and as will be recognized from later drawings (FIGS.
19A-C), the main body 103 of the bracket body insert 100 can be
fabricated in different thickness dimensions and consequently,
provides a means once it is received within the arch wire slot 60
by which the orthodontic bracket 20 can be provided with a
resulting arch wire slot 60 having a selectively variable
cross-sectional dimension in order to achieve the benefits of the
present invention. Further, it will be recognized by reversing the
direction of the main body 103, within the arch wire slot 60, the
same bracket body insert 100 can appropriately position the bracket
body 40 in a multiplicity of possible, and different, angular
orientations relative to the bracket base 21, so as to provide a
multiplicity of treatment options for a clinician employing the
same orthodontic bracket 20 to correct the misalignment of a
patient's tooth 11.
[0057] The bracket body 100 further includes first and second
engagement portions 111 and 112, respectively, and which are
located at the first and second ends 101 and 102 of the bracket
body insert 100. In particular, the first and second engagement
portions 111 and 112 extend outwardly beyond of the first and
second sides 44 and 45 of the bracket body 40, and further provide
a convenient means by which a clinician (not shown) may easily,
visually identify the bracket body insert 100 such that it ray be
positioned appropriately or otherwise adjusted as will be discussed
in further detail, below. Each of the engagement portions 111 and
112 respectively, have an outside facing surface 113 which has
formed therein a depression or cavity 114 which allows a clinician
to insert a tool like tweezers or the like in the depression in
order to conveniently remove the bracket body insert 100 from the
arch wire slot 60. As will be seen in FIG. 6, the bracket body
insert 100 also includes a first, engagement member 115 which
extends normally, downwardly relative to the first end 101 of the
bracket body. The first engagement member is dimensioned so as to
be slideably received within the first passageway 71 which is
formed in the first side 44 of the bracket body 40. Still further,
the bracket body insert 100 includes a second engagement member
116, which is shorter in length than the first engagement member
115, and which further is received in the second passageway 72, and
which is formed in the second side 45 of the bracket body 40. The
first engagement member 115 has a distal end 117 which is operable
to be matingly received within one of the multiplicity of
engagement regions 36 which are formed in the bracket base 21. As
will be recognized, when the main body 103 of the bracket body
insert 100 is appropriately inserted within the arch wire slot 60,
the distal end 117 of the engagement member 115 is received within
one of the multiplicity of engagement regions 36, and thereby is
effective in fixedly, rotatably positioning the bracket body 40 in
an appropriate rotatable orientation relative to the bracket base
22. Further, and as will be recognized from later drawings (FIGS.
19A-C), the main body 103 of the bracket body insert can be
fabricated in different thickness dimensions and consequently,
provides a means by which the orthodontic bracket 20 can be
provided with an arch wire slot 60 having variable cross-sectional
dimensions in order to achieve the benefits of the present
invention. Further, it will be recognized by reversing the
direction of the main body 103, within the arch wire slot 60, the
same bracket body insert 100 can appropriately position the bracket
body 40 in five possible angular orientations relative to the
bracket base 21, so as to provide a multiplicity of treatment
options for a clinician employing the same orthodontic bracket 20
to correct the misalignment of a patient's tooth 11.
[0058] As illustrated in the drawings, the bracket body 40 is shown
in the first form of the invention 20 as being partially, rotatably
movable relative to the bracket base 21 in a given axis of
movement, here shown in a vertical direction when the bracket base
21 is mounted on the anterior facing surface 12 of the patient's
tooth 11. In the first form of the invention 20, the arch wire slot
60 is located in a fixed orientation relative to the bracket body
40. This is in contrast to the second form of the invention as will
be discussed, hereinafter and wherein the arch wire slot is
selectively movably adjustable relative to the bracket body 40 as
will be discussed, hereinafter. As noted above, the cross-sectional
dimension of the arch wire slot 60 is defined by opposed, and
predetermined, spaced top and bottom surfaces 63 and 64, and a
supporting rear wall 65 which extends between the top and bottom
surfaces 63 and 64 of the arch wire slot 60. However, when the
bracket body insert 100 is received in the arch wire slot 60, the
anterior facing surface 106 of the bracket body insert 100 acts or
becomes the supporting rear wall 65 of the resulting arch wire slot
60 and which receives the arch wire 90. In this arrangement the
anterior facing surface 106 is selectively adjustable relative to
the spaced top and bottom surfaces 63 and 64 so as to provide the
selective cross-sectional dimension for the aforementioned arch
wire slot 60. In the of the present invention, the cross-sectional
dimension of the arch wire slot 60 may be rendered substantially
uniform when measured in a direction which extends between the
first and second ends 61 and 62 thereof. However, in an alternative
form of the invention, the cross-sectional dimension of the arch
wire slot 60 may be rendered non-uniform when measured in a
direction extending between the first and second ends 61 and 62 of
the arch wire slot 60. Such is best understood by studying FIGS.
19A, B and C, respectively.
[0059] The orthodontic bracket 10 as shown in the first form of the
invention 20 includes a bracket body insert 100 which is releasably
received within the transversely disposed arch wire slot 60, and
which further has a main body 103 which forms, at least in part, a
portion of the arch wire slot 60 as noted, above by filling or
occupying a portion of the volume thereof. The main body 103 of the
bracket body insert 100 substantially adjustably fixes the
rotatable orientation of the bracket body 40 relative to the
bracket base 21. In the form of the invention as disclosed, the
main body 103 of the bracket body insert 100, and which forms a
portion of the arch wire slot 60, has a uniform dimension. However,
as noted above, the main body 103 of the bracket body insert 100,
and which forms a portion of the arch wire slot 60, may have a
non-uniform dimension, (FIGS. 19B, 19C). The change in the
dimensions of the main body 103 of the bracket body insert 100
provides a convenient means for changing the resulting
cross-sectional dimensions of the arch wire slot 60 and which
cooperates with the arch wire 90. This change in the dimension of
the resulting arch wire slot 60 allows a clinician to impart
horizontal movement to the arch wire 90 so as to facilitate one of
the orders of movement for the patient's tooth 11. In the form of
the invention 20, as illustrated, the bracket base 21 further
includes a multiplicity of engagement regions 36 which are formed
in a predetermined spacial pattern in the bracket base 21. The
bracket body insert 100 has an engagement member 115 having a
distal end 117, and which is operable to be received within one of
the multiplicity of engagement regions 36 which are formed in the
bracket base 21. The receipt of the distal end 117 of the
engagement member 115 in one of the engagement regions 36
releasably fixes the rotatable orientation of the bracket body 40
relative to the bracket base 21.
[0060] More specifically, the present invention includes, in a
first form, an orthodontic bracket 20 having a bracket base 21
which is releasably affixed to an anterior facing surface 12 of a
patient's tooth 11, and a bracket body 40 which movably cooperates
with the bracket base 21. The bracket body 40 has an anterior
facing surface 42 which defines, at least in part, a transversely
disposed arch wire slot 60 which communicates with the anterior
facing surface of the bracket body 40. In the first form of the
invention, a bracket body insert 100 is provided, and which is
further releasably received within the transversely disposed arch
wire slot 60, and which further forms, at least in part, a portion
of the transversely disposed arch wire slot 60 by occupying a
portion of the volume of the arch wire slot 60. The bracket body
insert 100 further selectively and adjustably fixes the orientation
of the movable bracket body 40 relative to the bracket base 21. In
the first form of the invention, an arch wire 90 is received in the
transversely disposed arch wire slot 60. The movable bracket body
40, acting in combination with the bracket body insert 100, each
respectively engage the arch wire 90 so as to provide a
multiplicity of torque expressions which individually forcibly act
on the patient's tooth 11, and which further cause first, second
and third orders of movement 13, 14 and 15, respectively. These
first, second and third orders of movement are achieved typically
by utilizing the same arch wire 90. As earlier discussed, the
transversely disposed arch wire slot 60 has a cross-sectional
dimension, and the bracket body insert 100 is operable to
selectively adjust the cross-sectional dimension of the
transversely disposed arch wire slot 60 so as to allow a clinician
to impart these respective movements to the patient's tooth 11.
[0061] More specifically, the present invention includes, in a
first form, an orthodontic bracket 20 having a bracket base 21
which is releasably affixed to an anterior facing surface 12 of a
patient's tooth 11, and a bracket body 40 which movably cooperates
with the bracket base 21. The bracket body 40 has an anterior
facing surface 42 which defines, at least in part, a transversely
disposed arch wire slot 60 which communicates with the anterior
facing surface of the bracket body 40. In the first form of the
invention, a bracket body insert 100 is provided, and which is
further releasably received within the transversely disposed arch
wire slot 60, and which further forms, at least in part, a portion
of the transversely disposed arch wire slot 60. The bracket body
insert 100 further selectively and adjustably fixes the orientation
of the movable bracket body 40 relative to the bracket base 21. In
the first form of the invention, an arch wire 90 is received in the
transversely disposed arch wire slot 60. The movable bracket body
40, acting in combination with the bracket body insert 100, each
respectively engage the arch wire 90 so as to provide a
multiplicity of torque expressions which individually forcibly act
on the patient's tooth 11, and which further cause first, second
and third orders of movement 13, 14 and 15, respectively. These
first, second and third orders of movement are achieved typically
by utilizing the same arch wire 90. As earlier discussed, the
transversely disposed arch wire slot 60 has a cross-sectional
dimension, and the bracket body insert 100 is operable to
selectively adjust the cross-sectional dimension of the
transversely disposed arch wire slot 60 so as to allow a clinician
to impart these respective movements to the patient's tooth 11.
[0062] As will be recognized from the drawings, the engagement
regions 36, which are formed in the bracket base 21, are located
either on one side, or on both sides of the coupling portion 30.
Still further, and in another form of the invention, the engagement
regions 36 may be formed directly into the coupling portion 30 of
the bracket base 21. In one form of the invention, the transversely
disposed arch wire slot 60 is defined, in part, by spaced top and
bottom surfaces 63 and 64 as earlier disclosed. Still further, the
bracket body insert 100 has an elongated main body 103 which is
sized so as to fit within the arch wire slot 60 and further fills
or occupies at least a portion of the volume thereof. As earlier
disclosed, the main body 103 of the bracket body insert has an
anterior facing surface 106 which forms or acts as a supporting
rear wall 65--of the transversely disposed arch wire slot 60, and
which further extends between the top and bottom surfaces 63 and 64
of the arch wire slot 60. The thickness dimension of the main body
103 of the bracket body insert 100 is selectively variable so as to
cause the transversely disposed arch wire slot 60 to have a
selective predetermined cross-sectional dimension. Consequently,
upon receipt of the arch wire 90 within the transversely disposed
arch wire slot 60, a clinician can easily cause first, second and
third order movements to be imparted to specific patient's teeth 11
thereby providing clinical benefits not possible, heretofore.
[0063] As will be recognized from the drawings, the engagement
regions 36, which are formed in the bracket base 21, are located
either on one side, or on both sides of the coupling portion 30.
Still further, and in another form of the invention, the engagement
regions 36 may be formed directly into the coupling portion 30 of
the bracket base 21. In one form of the invention, the transversely
disposed arch wire slot 60 is defined, in part, by spaced top and
bottom surfaces 63 and 64 as earlier disclosed. Still further, the
bracket body insert 100 has an elongated main body 103 which is
sized so as to fit within the arch wire slot 60. As earlier
disclosed, the main body 103 of the bracket body insert has an
anterior facing surface which forms a back wall 106 of the
transversely disposed arch wire slot 60, and which further extends
between the top and bottom surfaces 63 and 64 of the arch wire slot
60. The thickness dimension of the main body 103 of the bracket
body insert 100 is selectively variable so as to cause the
transversely disposed arch wire slot 60 to have a selective
predetermined cross-sectional dimension. Consequently, upon receipt
of the arch wire 90 within the transversely disposed arch wire slot
60, a clinician can easily cause first, second and third order
movements to be imparted to specific patient's teeth 11 thereby
providing clinical benefits not possible, heretofore.
Second Form of the Invention
[0064] The second form of the invention 120 is best seen in FIGS.
7-11, respectively. The second form of the invention 120 operates,
to a large degree, in a very similar fashion relative to the first
form of the invention 20. In particular, the second form of the
invention 120 includes a bracket base 121 which is formed of a pad
122 having a peripheral edge 123, and which further has an anterior
facing surface 124, and an opposite posterior facing surface 125
which is, again, adhesively affixed to the anterior facing surface
12 of a patient's tooth 11. The second form of the invention 120
includes a coupling portion 130 which is best seen by reference to
FIG. 10. The coupling portion 130 which is made integral with the
anterior facing surface 124, again, defines a curved dove tailed
shaped slot 131. The curved dove tailed shaped slot 131 is defined,
in part, by inclined sidewalls which are generally indicated by the
numeral 132. The curved dove tailed shaped slot 131 is somewhat
truncated when viewed in cross-section as best seen in FIG. 10. The
coupling portion 130 includes a curved, upwardly facing surface 133
which is operable to matingly cooperate with the bracket body as
will be described, below. Further, and as seen in FIG. 10, a
multiplicity of engagement regions 134 are formed in the curved
upwardly facing surface 133 of the coupling portion 130, and
operate in a fashion similar to that described in the first form of
the invention 20. Although, it should be noted, that these
engagement regions are not accessible from either the mesial or
distal side of the bracket base.
[0065] The second form of the invention 120 includes a bracket body
140 which is similar to that which was earlier described. The
bracket body 140 is movably borne by the bracket base 121, and
further has a main body 141 which has an anterior facing surface
142, and an opposite, posterior facing surface 143. Additionally,
the bracket body 140 has a first or mesial side 144, and an
opposite, second, or distal side 145. Again, the bracket body has a
superior facing surface 146, and an inferior facing surface 147.
Again, as earlier described, the second form of the invention has a
movable gate 150 which is operable to reciprocally move along a
given path of travel in order to selectively occlude an arch wire
slot 160 which is defined, in part, by the bracket body 140. The
arch wire slot 160 has opposite first and second ends 161 and 162,
respectively, and top and bottom surfaces 163 and 164. The top and
bottom surfaces 163, 164 respectively are disposed in
predetermined, substantially parallel, spaced relation. Still
further, the main body 141 defines a supporting rear wall 165 which
extends between the top 163 and bottom 164 surfaces, and which
further is located within the main body 141 of the bracket body.
Additionally, the arch wire slot 160 has a central portion or
region 166. Located endwardly of the arch wire slot 160 are
individual passageways 170, here indicated in the drawings as first
and second passageways 171 and 172, and which individually extend
posteriorly, inwardly relative to the bracket body 140. The first
and second passageways are operable to individually, matingly
cooperate, at least in part, with a portion of the bracket body
insert as will be described, below. Again, as was described with
the first form of the invention 20, the second form 120 has a
complimentary substantially uniformly curved posterior facing
surface which is generally indicated by the numeral 180. Still
further, and made integral with the posterior surface 180 is a male
pin member 181 which is similar to that which was earlier described
with respect to the first form of the invention 20. The male pin
member 181 has a complimentary curved surface which is operable to
be received in interfitted mating, sliding relation within the
curved dove tailed shaped slot 131 which is defined by the coupling
portion 130 of the bracket base 121. Again, the arch wire slot 160
is operable to receive an arch wire 190 of traditional design.
Additionally, the second form of the invention 120 has a bracket
body insert which is generally indicated by the numeral 200, and
which is received within the arch wire slot 160 before the arch
wire 190 is inserted. The bracket body insert 200 has opposite
first and second ends 201 and 202, respectively. (FIGS. 11A-11D).
As will be noted, when comparing the bracket body insert 200 with
that of the bracket body insert 100, it will be seen that the main
body 203 of the bracket body insert 200 has a length dimension
which does not exceed the length of the arch wire slot 160 such
that the first and second ends 201, and 202 are substantially flush
or co-planar with the mesial and distal surfaces 144, and 145 of
the bracket body 140. Therefore, in this form of the invention, the
bracket body insert 200, working in combination with the bracket
body 140, provides a more aesthetically appealing exterior
appearance once the orthodontic bracket 10 is mounted on the
anterior facing surface 12 of the patient's tooth 11. The bracket
body insert 200, as illustrated, includes a top or superior facing
surface 204, and an opposite, bottom or inferior facing surface
205. The distance, as measured between the top and bottom surfaces
204 and 205, represent a height dimension which is less than about
the dimension as measured between the top and bottom surfaces 163
and 164 of the arch wire slot 160. Again, as was described with the
first form of the invention 20, the main body 203 of the bracket
body insert 200 includes an anterior facing surface 206 which forms
a supporting rear wall of the arch wire slot 160. Still further,
the main body 203 has a posterior facing surface 207 which rests in
juxtaposed relation thereagainst the supporting rear wall 165 which
is defined by the main body 141 of the bracket body 140. Again, as
was discussed with the first form of the bracket body insert 100,
the relative thickness dimension as measured between the anterior
and posterior facing surfaces 206 and 207 may be, on the one hand
uniform, or on the other hand may be variable. Because of the
variation in the thickness dimension of the bracket body insert
200, the resulting arch wire slot 160 can have a variable
cross-sectional dimension. This variable cross-sectional dimension
permits a clinician to readily and easily adjust the torquing
couples applied to given patient's teeth 11 to achieve the clinical
objectives they have predetermined for a patient's orthodontic
treatment plan.
[0066] The bracket body insert 200 as used in the second form of
the invention 120 again includes a first, and longer dimensioned
engagement member 211 which is mounted on the first end 201, and
which is further positioned substantially perpendicular relative
thereto. Additionally, the bracket body insert 200 includes a
second engagement member 212 which extends normally downwardly
relative to the second end 202. The first and second engagement
members 211, 212 are dimensioned to be slideably received within
the individual passageways 171 and 172, which are formed endwardly
of the arch wire slot 160. The first, and longer of the engagement
members 211 has a distal end 213 which is operable to be
releasably, and matingly received within one of the multiplicity of
engagement regions 134, and which are formed in the coupling
portion 130 of the bracket base 121. When received in one of these
engagement regions 134, the bracket body insert 200 is operable to
substantially releasably and rotatably fix the movable bracket body
140 relative to the bracket base 121, thereby achieving the
orthodontic benefits as earlier described. Again, the dimensions of
the bracket body insert 200 are such that it provides a much more
appealing and aesthetically pleasing orthodontic bracket which can
be used on a patient's teeth 11.
Third Form of the Invention
[0067] The third form of the invention is generally indicated by
the numeral 230 and is best seen in FIGS. 12 and 13A, 13B and 13C,
respectively. In the third form of the invention 230, the structure
and function is somewhat similar to that described with respect to
the first 20 and second 120 forms. Various features of the third
form of the invention 230 are therefore not illustrated in the
attached drawings so as to expedite an understanding of the present
form of the invention. Although it will be understood that
structures previously disclosed would be present in a final,
completed product. The third form of the invention 230 is similar
to the first and second forms 20 and 120, respectively, and has a
bracket base including a coupling portion similar to that earlier
described. Therefore, repetition of that structure is unwarranted.
The third form of the invention 230 as seen in FIG. 12 includes a
movable bracket body 240 which is borne on the bracket base (not
shown). The bracket body 240 similarly would include a movable gate
(not shown) for selectively occluding an arch wire slot 260 as will
be described, below. However, the gate is removed to show the
structure thereunder. The bracket body 240 includes a main body 241
which has an anterior facing surface 242 which is seen in FIG. 12.
The bracket body 240 also has a first or mesial side 244, and a
second or distal side 245. Again, the main body 241 has a superior
facing surface 246, and an opposite inferior facing surface 247.
The main body 241 defines, in part, an arch wire slot 260 which is
similar to that which is earlier described. The arch wire slot 260
has opposite first and second ends 261 and 262, respectively, and
further defines a top and bottom surface 263 and 264 respectively.
The top 263 and bottom 264 surfaces are again located in
predetermined substantially parallel spaced relation one relative
to the other. Again, the main body 241 defines a supporting rear
wall 265 which extends between the top and bottom surfaces 263 and
264, respectively. As seen in FIG. 12, a pair of passageways 266
are formed through the supporting rear wall 265, and communicate
with the posterior facing surface of the bracket body 240. The
respective passageways 266 are operable to be substantially
coaxially aligned with one of the multiplicity of engagement
regions which are formed in the bracket base (not shown), and which
allow a bracket body insert, as will be described, below, to engage
the supporting bracket base, thereby releasably, rotatably fixing
the movable bracket body 240 relative to the bracket base as was
described with the first and second forms of the invention 20 and
120, respectively. As further seen in FIG. 12, it will be noted
that individual recessed regions 267 are formed in the main body
241, and are positioned endwardly relative to the arch wire slot
260. Further,the arch wire slot 260 has a central portion or region
268.
[0068] Referring now to FIGS. 13A, B and C, respectively, it will
be seen that the third form of the invention 230 includes a bracket
body insert 300. The bracket body insert 300 has first and second
ends 301 and 302, respectively. As will be recognized from the
drawings, and as was discussed previously with the second form of
the invention 120, the main body 303 of the bracket body insert 300
has a length dimension which is less than about the distance as
measured between the opposite first or mesial side 244, and the
second or distal side 245 of the bracket body 240. Therefore, the
main body 303 may be received within and form a portion of the arch
wire slot 260, but will not typically extend beyond the opposite
sides of the bracket body 240 thereby providing an aesthetically
appealing appearance to the orthodontic bracket 10. The bracket
body insert 300 further has a top or superior facing surface 304,
and a bottom or inferior facing surface 305. Again, the main body
303 has an anterior facing surface 306 which forms a rear wall of
the arch wire slot 260. Again, the thickness dimension of the main
body 303 as measured between the anterior facing surface 306, and
an opposite posterior facing surface 307 provides a convenient
means whereby the bracket body insert 300, once received in the
arch wire slot 260, can conveniently, adjustably alter or change
the cross-sectional dimension of the arch wire slot so as to
provide a convenient means for a clinician to provide selective
torquing couples to an arch wire, and thereby provide the many
clinical benefits to a patient as was discussed earlier in this
application. Similar to the previously described other forms of the
invention, the bracket body insert 300 includes a first, and longer
engagement member 311 which extends normally downwardly from a
location near the first end 301. The first, or longer, engagement
member 311 is dimensioned so as to be received in one of the
passageways 266 which are formed in the supporting rear wall 265 of
the main body 241. The bracket body insert 300 further has a
second, or shorter, engagement member 312. Again, this second
shorter member 312 is located at a position near the second end
302, and which extends normally downwardly therefrom. Again, the
second, shorter engagement member 312 is dimensioned to be received
in one of the passageways 266 as earlier described. In this form of
the invention 230, the bracket body insert 300 further includes
individual movement restraining members 313 which extend normally
downwardly from the opposite first and second ends 301 and 302,
respectively. The individual movement restraining members 313 are
sized so as to be matingly received within the recessed regions 267
which are formed in the main body 241 of the bracket body 240, and
which are respectfully located endwardly relative to the arch wire
slot 260. As will be recognized from reviewing the drawings, the
individual movement restraining members 313 have a cavity 314
formed therein. This cavity 314 provides a convenient means whereby
a clinician may use a tool such as tweezers, and the like to
forcibly engage the bracket body insert 300 and remove it from the
bracket body 240. As will be recognized, the thickness dimension of
the main body 303 may be varied so as to provide the various
torquing couples necessary for appropriate orthodontic treatment.
Still further, the bracket body insert 300 may be taken from the
bracket body 240 and reversed in direction and then reinserted back
in the arch wire slot 260 so as to provide a convenient means
whereby the clinician may have a bracket body insert which performs
and is able to achieve assorted torquing couples for effective
orthodontic treatment of a patent. This feature is common to all
the bracket body inserts described in this patent application.
Fourth Form of the Invention
[0069] The fourth form of the invention is generally indicated by
the numeral 400 and is best seen in FIGS. 14-19, respectively. In
the fourth form of the invention 400, the orthodontic bracket 10,
as will be described, includes a bracket base 401 similar to that
which was earlier described with the other forms of the invention
20, 120, and 230, respectively. The bracket base 401 has an
anterior facing surface 402, and an opposite, posterior facing
surface 403 which is suitably adhesively affixed to the anterior
facing surface 12 of a patient's tooth 11 to achieve the
orthodontic benefits as described in this application. The bracket
base 401 further is defined by a peripheral edge 404. As seen in
FIG. 14, and following, the fourth form of the invention 400
includes an immovable bracket body 410 which is affixed to, or
otherwise made integral with, the bracket base 401. The bracket
body 410 has an anterior facing surface 411, and an opposite
posterior facing surface 412 which is made integral with the
bracket base 401. Still further, the immovable bracket body 410 has
a first or mesial side 413, and an opposite or distal side 414.
Again, the bracket body 410 includes a superior facing surface 415,
and an opposite inferior facing surface 416. The superior and
inferior facing surfaces define respective tie wings 417 which are
operable to be engaged by a suitable ligature 418 as seen in FIG.
15. The ligature 418 as illustrated is not drawn to scale so as to
allow an illustration of the present invention.
[0070] The fourth form of the invention 400, and more specifically
the immovable bracket body 410, thereof, includes or otherwise
defines a transversely disposed, and substantially cylindrically
shaped cavity 420 which extends between the first, mesial side 413,
and the second, distal side 414. The transversely disposed cavity
420 has opposite first and second ends 421 and 422, respectively.
Further, and as best seen in FIG. 17, a curved elongated male pin
member which is generally indicated by the numeral 423, is
positioned substantially between the first and second ends 421 and
422, and further extends generally radially, inwardly relative to
the transversely disposed cavity 420. The curved elongated male pin
member is similar in its overall construction, and function, to the
male pin member 81 as was described in the first form of the
invention 20. In this regard, the curved elongated male pin member
423 is defined by a main body 424 which is made integral with the
immovable bracket body 410. The main body 424 further includes a
substantially centrally disposed supporting portion or member 425,
and further an enlarged flange member 426 is mounted on, or made
integral with, the supporting member 425, and extends normally
outwardly therefrom to form a substantially T-shaped structure. The
enlarged flange member 426 has a curved, upwardly facing surface
427. The curved, elongated male pin member 423 is operable to
matingly interfit, and slideably cooperate with a dove tail shaped
slot which is made integral with an arch wire insert. This
structure will be discussed in greater detail in the paragraphs
below. As seen in FIG. 17, a multiplicity of engagement regions 430
are formed in the immovable bracket body 410 and communicate with
the transversely disposed substantially cylindrically shaped cavity
420. Again, the multiplicity of engagement regions 430 operate in a
similar fashion to that earlier described with respect to the
earlier forms of the invention. As will be seen in the drawings,
the immovable bracket body 410 defines an aperture 428 which is
formed in the anterior facing surface 411 of the immovable bracket
body 410. The aperture communicates with the transversely disposed
cavity 420, and further has a predetermined cross-sectional
dimension. This feature will also be discussed in greater detail
below.
[0071] The fourth form of the invention 400 further includes an
arch wire insert which is generally indicated by the numeral 440,
and which is best understood by a study of FIG. 18. The arch wire
insert 440 has opposite ends 441 and 442. The distance between the
opposite first and second ends 441 and 442 is equal to or less than
the distance as measured between the first, mesial side 413, and
the second or distal side 414 of the immovable bracket body 410.
Still further, the arch wire insert 440 has a main body 443 which
is defined by a longitudinal axis 444. The main body is dimensioned
such that it may not pass out through the aperture 428. However, a
portion of the main body 443 extends anteriorly outwardly relative
to the aperture 428. The main body 443 is selectively rotatable
about the longitudinal axis 444 when the arch wire insert 440 is
telescopingly and rotatably received within the transversely
disposed cavity 420 as described below. The main body 443 further
has an anterior facing surface 445, and an opposite posterior
facing surface 446. The main body 443 also has an exterior facing
surface 447 which is substantially cylindrically shaped, and which
is further dimensioned for rotatable, telescoping receipt within
the transversely disposed and substantially cylindrically shaped
cavity 420.
[0072] As seen in FIG. 18, a curved dove tailed shaped slot 450 is
formed in the exterior facing surface 447, and operates in a manner
similar to the curved, dove tailed shaped slot 31 as earlier
described in the first form of the invention 20. The curved dove
tailed shaped slot 450 has a complimentary, curved, bottom surface
451 which slideably, and matingly cooperates with the curved
upwardly facing surface 427 of the elongated male pin member 423
which was earlier described. The curved dove tailed shaped slot 450
has individual flange members 452 which extend towards one another,
and which respectively cause the curved dove tailed slot 450 to
assume a T-shaped configuration. However, it will be recognized
that other shapes can work with equal success. Still further, it
should be understood that the structure disclosed herein, that
being, the curved elongated male pin member 423 and the curved dove
tailed slot 450 may be exchanged, or otherwise substituted, one for
the other, and the invention will operate with the same degree of
success. The main body 443 of the arch wire insert 440 further
defines an arch wire slot 460. The arch wire slot has opposite
first and second ends 461 and 462, respectfully. The arch wire slot
460 is further defined by a top surface 463, and a bottom surface
464. As was earlier described, the arch wire slot 460 has top and
bottom surfaces 463 and 464, and which are disposed in
predetermined, substantially parallel, spaced relation one relative
to the other. The main body 443 of the arch wire insert 440 further
defines a supporting rear surface 465 which connects the top 463
and bottom 464 surfaces together. As will be seen in FIG. 18, a
pair of passageways 466 are formed through the supporting rear
surface 465, and further allow the arch wire slot 460 to
communicate with the multiplicity of engagement regions 430 which
are formed in the immovable bracket body 410. This feature will be
discussed in greater detail, below. As will be seen from a study of
FIG. 18, it will be recognized that the supporting rear surface
465, in combination with the top and bottom surfaces 463 and 464
respectively define individual recessed regions 467 which are
located near the first and second ends 441 and 442 of the arch wire
insert 440. These recessed regions 467 have a predetermined
cross-sectional dimension which facilitates the receipt of a
bracket body insert which will be received within the arch wire
slot 460, and which is discussed in greater in the paragraphs,
which follow.
[0073] The fourth form of the invention 400 further includes a
bracket body insert which is generally indicated by the numeral
480, and which is best understood by a study of FIGS. 19A, 19B and
19C, respectively. In this regard, the bracket body insert 480 has
opposite first and second ends 481 and 482, respectively. The
distance between the opposite first and second ends 481 and 482 is
substantially equal to, or less than the distance as measured
between the opposite ends 441 and 442 of the arch wire insert 440.
As will be recognized, the bracket body insert 480, as depicted,
typically does not extend beyond the first and second sides 413 and
414 of the immovable bracket body 410. However, it will be
recognized that the bracket body insert 480 may be made longer so
as to extend outwardly relative to the opposite sides of the
immovable bracket body 410 in order to facilitate the use of the
bracket body 410 by being easier to see, or grasp by the clinician
as the bracket body insert 480 is inserted or withdrawn from the
arch wire slot 460. The bracket body insert 480 includes a main
body 483 which has an anterior facing surface 484, and which forms
a supporting rear wall that defines, in part, the arch wire slot
460. Still further, the main body 483 has an opposite, posterior
facing surface 485 which lies in rested, juxtaposed relation,
thereagainst, the supporting rear surface 465 as defined by the
arch wire insert 440. The bracket body insert 480 further defines
top and bottom surfaces 486 and 487, respectively. The top and
bottom surfaces are disposed in substantially parallel, spaced
relation, one relative to the other. The distance between the top
and bottom surfaces 486 and 487, respectively, is less than about
the distance as defined between the top and bottom surfaces 463 and
464, and which define, in part, the arch wire slot 460. Therefore,
it will be recognized that that bracket body insert 480 may be
received within the arch wire slot 460 and further cooperates with
same. As was the case with the other forms of the invention, the
bracket body insert 480 includes a first, elongated, and longer
dimensioned engagement member 491 which extends normally downwardly
from a location near the first end 481. Still further, the bracket
body insert 480 includes a second, and smaller engagement member
492 which extends from a location near the second end 482. The
first and second engagement members 491 and 492, respectively, have
a predetermined shape such that they may be matingly received and
pass through the respective passageways 466 which are formed in the
supporting rear surface 465 of the arch wire insert 440, as was
earlier described. The first and the longer of the engagement
members 491, has a distal end 493 which is operable to be received
within one of the multiplicity of engagement regions 430 which are
formed in the immovable bracket body 410. Similar to that which was
discussed with the other forms of the invention, the receipt of the
distal end 493 in one of the multiplicity of engagement regions 430
is effective in fixedly, adjustably positioning the arch wire
insert 440 in a given predetermined rotational orientation relative
to the immovable bracket body 410 to achieve the benefits of the
present invention. As will be seen by comparing the views of FIGS.
19A, 19B and 19C, respectively, the main body 483 may have a
variable thickness dimension as measured between the anterior
facing surface 484, and the posterior facing surface 485. As noted
above, the anterior facing surface 484 forms a part of the arch
wire slot 460. Because of the variable thickness dimension as
provided by the arch wire insert 440, the arch wire insert 440 is
able to variably adjust the cross-sectional dimension of the arch
wire slot 460 which is defined between the surfaces 463, 464 and
the anterior facing surface 484 of the bracket body insert 440
which forms the supporting rear wall of the arch wire slot 460. As
seen in FIGS. 19A, 19B and 19C, respectively, the bracket body
insert 480 further includes movement restraining members 494 which
extend normally downwardly from the opposite first and second ends
481 and 482. These movement restraining members 494 are sized so as
to be appropriately matingly received within the recessed regions
467 which are positioned endwardly of the arch wire slot 460 as
earlier disclosed. Still further, as seen in FIGS. 19A, 19B and 19C
respectively, a cavity 495 is formed in the movement restraining
members 494, and which facilitate the gripping of the bracket body
insert 480 by the clinician, or by the use of a tool employed by
the clinician, in order to remove or place the bracket body insert
480, in an appropriate orientation within the arch wire slot
460.
Fifth Form of the Invention
[0074] The fifth form of the invention is best understood by FIGS.
20A, 20B, 20C and 200, respectfully. In the fifth form of the
invention it will be understood that the invention relates to a
variation in the bracket body insert 500 which may be employed and
utilized in the various forms of the invention discussed in this
application. In this regard, it will be understood that the bracket
body insert 500 as seen in FIGS. 20A, 20B, 20C and 200,
respectively, can be received in the previously described arch wire
slots, of the several forms of the invention previously described.
Again, the bracket body insert 500 may be utilized, on the one
hand, to fix a selectively rotatably movable bracket body as seen
in the first form of the invention 20, or further it may be
employed to selectively rotatably fix an arch wire insert as seen
in the fourth form of the invention 400. Again, the bracket body
insert 500 is received within an arch wire slot as defined by a
bracket body as employed on the orthodontic bracket 10. Again, the
bracket body insert 500 has first and second ends 501 and 502,
respectively, and a main body 503, which has a height dimension
which allows it to be readily received within the arch wire slot.
Again, the length of the bracket body insert 500 as measured
between the first 501 and second 502 ends may be the same length as
the arch wire slot, or may further extend outwardly therefrom so as
to provide a convenient means for grasping the bracket body insert
500 by the clinician as the bracket body insert 500 is placed into,
or removed from the arch wire slot. The bracket body insert 500 has
an anterior facing surface 504 which forms a portion of the
corresponding arch wire slot. Again, the thickness dimension of the
main body 503 can either be uniform, or non-uniform, depending upon
the clinical situation being addressed on a patient's tooth 11.
Again, the main body 503 has a posterior facing surface 505 which
is located within the movable or immovable bracket body depending
upon the form of the invention being employed. The main body 503
also has top and bottom surfaces 506 and 507, respectively. Again,
the distance as measured between the top 506 and bottom 507
surfaces is less than about the distance as measured between the
top and bottom surfaces which define, in part, the arch wire slot
into which the bracket body insert 480 is being placed. In the
fifth form of the invention 500, a pair of rigid planar surfaces
510 extend substantially normally outwardly relative to the
anterior facing surface 504, and in a substantially coplanar
orientation relative to the top and bottom surfaces 506 and 507,
respectively of the main body 503. The pair of planar surfaces 510
include first and second planar surfaces 511 and 512, respectively.
The first 511 and second 512 planar surfaces are substantially
parallel to each other, and are further attached to the main body
503 at a weakened joint which is generally indicated by the numeral
dotted line 513. The first 511 and second 512 planar surfaces
define a reduced dimensioned predetermined cross-sectional region
514. This region 514 would, of course, be oriented within the
existing arch wire slot as defined either by the bracket body, or
the arch wire insert depending on the form of the invention as
shown. However, this reduced dimension cross-sectional region 514
provides a clinician with yet another way of using smaller
dimensioned arch wires in order to finely adjust the position of a
patient's teeth 11 in order to provide a completed orthodontic
treatment which puts all teeth of the patient in an appropriate
orientation.
[0075] The first 511 and second 512 planar surfaces, as illustrated
in FIGS. 20B and 20C, respectively, can be individually removed by
the application of force which is applied to the individual planar
surfaces 511 and 512, respectively. This is accomplished by
breaking the first 511 or second 512 planar surfaces away at the
weakened joint 513. In this manner, the clinician can adjust the
relative orientation of the predetermined cross-sectional region
514 in the arch wire slot which receives the arch wire. This
feature provides a multitude of treatment options and allows a
clinician to use variously sized and dimensioned arch wires to
finely adjust the final position of an individual patient's teeth
11 in a manner not possible, heretofore. The main body 503 further
includes a first and longer engagement member 521 which extends
from a position at or near the first end 501. Still further, and as
earlier discussed the main body 503 has a second, shorter
engagement member 522 which extends from a position near the second
end 502. Again, the first, and longer engagement member 521 has a
distal end 523 which is operable to be received in one of the
earlier described engagement regions formed in the bracket base, or
in the bracket body depending upon the form of the invention in
which the bracket body insert 500 is employed. Again, this same
bracket body insert 500 has opposing movement restraining members
524 which are mounted on the opposite first and second ends 501 and
502, respectively. The movement restraining members 524 each have a
cavity 525 which is formed therein, and which further gives a
clinician an opportunity to easily grasp or otherwise engage the
bracket body insert 500 to easily place it, or remove it, from the
arch wire slot of the bracket body upon which it is employed.
[0076] In its broadest aspect therefore, the present invention
includes an orthodontic bracket 400 which includes a bracket base
401 which is releasably affixed to an anterior facing surface 12 of
a patient's tooth 11, and a bracket body 410 is mounted on the
bracket base 401, and which further has an anterior facing surface
411 which defines a transversely disposed, and substantially
cylindrically shaped cavity 420. In the invention as disclosed, an
arch wire insert 440 having a main body 443 is defined, in part, by
a longitudinal axis 444, and which is further received within the
transversely disposed and substantially cylindrically shaped cavity
420. The main body 443 of the arch wire insert 440 further defines,
at least in part, a transversely disposed arch wire slot 460 having
a selectively adjustable cross-sectional dimension. The arch wire
insert 460 is selectively rotatable about the longitudinal axis 444
thereof. In one form of the invention, as disclosed, a bracket body
insert 480 is provided, and which is releasably received within the
transversely disposed arch wire slot 460, and which further has a
main body 483 which forms, at least in part, a portion of the arch
wire slot 460. The bracket body insert 480 substantially releasably
fixes the rotatable orientation of the arch wire slot 480 relative
to the bracket body 410, and further selectively adjusts the
cross-sectional dimension of the transversely disposed arch wire
slot 460 while the bracket base 401 is releasably attached to the
anterior facing surface 12 of the patient's tooth 11. In one form
of the invention as disclosed, an arch wire 435 is received within
the transversely disposed arch wire slot 460 and which, acting in
combination with the arch wire insert 440 provides a multiplicity
of selective torque expressions which individually forcibly act
upon the patient's tooth 11. These individual torque expressions
achieve predetermined first, second and third orders of movement
13, 14 and 15, respectively of the patient's tooth 11.
Sixth Form of the Invention
[0077] The sixth form of the invention is generally indicated in
FIGS. 21 through 24, respectively. The sixth form of the invention
600 includes a bracket base which is generally indicated by the
numeral 601. The bracket base, which is quite similar to that which
was earlier disclosed with the other forms of the invention,
includes a pad 602, which is defined by a peripheral edge 603. The
pad 602 has an anterior facing surface 604, and an opposite,
posterior facing surface 605. A coupling portion 610 Is made
integral with the anterior facing surface 604. The coupling portion
610 defines a curved, dove tail shaped slot, which is indicated by
the numeral 611 The coupling portion 610 is similar to that which
was earlier described with respect to the first form of the
invention 20. The curved dove tail slot 611 is further defined by a
pair of spaced, and angled sidewalls 612, as illustrated in the
drawings, and which forms a resulting truncated shaped passageway
or channel, which is operable to receive a feature of the
invention, which is made integral with the bracket body, as will be
described below. The respective sidewalls 612 define, in part, an
elevated, central region 613 of the coupling portion 610. The
elevated central region 613 has a curved upwardly facing surface
614, having a curvature similar to the posterior facing surface of
the bracket body, as will be described in the paragraph, below.
Additionally, as will be seen in the drawings, a pair of curved
guide channels 615 are formed on opposite sides of the curved dove
tail shaped slot 611 and are operable to matingly couple with
similar individual, curve-shaped rib structures which are formed in
the posterior facing surface of the bracket body as described in
the paragraph, below. As was described in the other forms of the
invention, a multiplicity of engagement regions 616, are formed in
the coupling portion 610, and are operable to be engaged by the
distal end of a bracket body insert, as will also be described,
below.
[0078] The sixth form of the invention 600 includes a bracket body
620, as seen in FIG. 21, and following. More specifically, the
bracket body 620, as seen in the drawings, includes a main body
621, which has an anterior facing surface 622 and an opposite,
posterior facing surface 623. In this regard the bracket body 620
has a superior facing surface 624, and an opposite inferior facing
surface 625. The superior and inferior facing surfaces 624 and 625,
respectively, define individual tie wings 626 which can be engaged
by a ligature, and which may be utilized when employing the bracket
body 620, which is illustrated in FIG. 23. With respect to the
bracket body as illustrated in FIG. 21, it will be understood that
the bracket body 620, as illustrated therein, is operable to
cooperate with a movable gate 627, and whose operation is well
known in the art. The bracket body 620, as seen in FIG. 23,
represents a bracket body upon which a ligature of conventional
design 627a can engage the aforementioned tie wings 626 in order to
secure the arch wire 628 therein. In this regard, the bracket body
620 defines an arch wire slot which is generally indicated by the
numeral 640. The arch wire slot 640, similar to that earlier
described, includes a top surface 641, and an opposite bottom
surface 642. Still further as seen in FIG. 24, a pair of
passageways 643 (only one of which is shown), is formed in the main
body 621 of the bracket body 620 and which are individually located
endwardly relative to the arch wire slot 640. The respective
passageways 643 are operable to matingly cooperate with individual
engagement members which are made integral with a bracket body
insert, as will be described, below. As further seen in FIG. 24,
the bracket body 620 defines a supporting rear wall 644, upon which
a bracket body insert may rest in juxtaposed mating relation. The
supporting rear wall 644 extends between the top and bottom
surfaces 641 and 642, respectively.
[0079] The sixth form of the invention 600, as seen in FIG. 21, and
following, includes a complimentary, uniformly curved surface 650,
which is made integral with the posterior facing surface 623. This
complimentary, uniformly curved surface 650 represents a male pin
member 651, which is sized so as to matingly, and movably coupled
with the coupling portion 610, and which is made integral with the
bracket base 601. The male pin member 651 is defined, in part, by
sidewall 652, which have an inclination similar to that of the
respective sidewalls 612, which form a portion of the curved dove
tail shaped slot 611. As seen in FIG. 24, it should be understood
that the male pin member 651 has a somewhat truncated shape when
viewed in cross-section, and which is dimensioned to be matingly
received within the curved, dove-tail shaped slot 611, which forms
a part of the coupling portion 610. Again, the male pin member 651
includes a complimentary curved surface 653 (FIG. 24), having a
curvature similar to the curved dove-tail shaped slot 611. Still
further, and as seen in FIG. 22, and adjacent to, and on the
opposite sides of the male pin member 651, are a pair of elongated,
and curved guide members 654, which are dimensioned to be received
within the pair of curved guide channels 615, as seen in FIG. 22.
The respective elongated guide members 654 are individually
operable to guide or otherwise direct the bracket body 620 along a
curved path of travel as it rotates within the coupling portion
610. As will be appreciated, and while the curved dove-tail shaped
slot 611 is shown having a concave-like shape, and the male pin
member 651, and more specifically the complimentary curved surface
653, is shown as being convexly shaped, it be recognized that these
respective shapes could be reversed, and positioned on the opposite
structure, and thus achieve the same benefits as provided for in
the present invention.
[0080] As illustrated in FIGS. 21 and 23, respectively, the sixth
form of the invention 600 works, in combination, with a bracket
body insert 660, and which is generally indicated by the numeral
660. The bracket body insert is similar in structure to that seen
in FIG. 6. The bracket body insert has a main body 661, which is
dimensioned to be received within an arch wire slot 640. Again, the
main body 661 has a top or superior facing surface 662, and an
opposite, bottom facing surface 663. The main body 661 is received,
and is positioned between, the top and bottom surfaces 641 and 642
of the arch wire slot 640. The bracket body insert 660 includes an
anterior facing surface 664, which forms the supporting rear wall
of the arch wire slot 640, and which further extends between the
top and bottom surfaces 641 and 642. Still further, the bracket
body insert 660 has a posterior facing surface (not shown) and
which rests in juxtaposed relation thereagainst the supporting rear
wall 644. Again, the thickness dimension as measured between the
anterior facing surface 664, and posterior facing surface can be
varied so as to allow the bracket body insert 660 to define an
adjustable arch wire slot 640, which has a variable, pre-determined
cross-sectional dimension which allows a clinician to apply varying
amounts of torque to the arch wire 628, and which is positioned
within the arch wire slot 640. Again, the bracket body insert 660
includes a pair of elongated engagement members 670, only one of
which is shown, (FIG. 21). One of the elongated engagement members
670, includes a distal end 671, which is operable to be received in
one of the multiplicity of engagement regions 616. Again, the
distal end 671 is operable to releasably, rotatably fix the
orientation of the bracket body 620, in a given orientation
relative to the bracket base 601. To adjust the sixth form of the
invention 600, the bracket body insert 660 may be grasped at the
respective recessed regions 672, which is formed in the main body
661, and moved anteriorly, outwardly relative to the arch wire slot
640. Thereafter, the bracket body 620 may be adjusted,
appropriately, and then the bracket body insert 660, and more
specifically the elongated engagement member 670, may be received
in one of the multiplicity of engagement regions 616. Thereafter,
the arch wire 628 may be placed back in the arch wire slot 640 and
either the gate 627 closed, or in the alternative, the arch wire
628 may be secured in the arch wire slot 640, by means of a
suitable ligature 627A, as seen in FIG. 23. The ligature as
illustrated is not drawn to an appropriate size so as to allow an
illustration of the inventive concepts.
[0081] The advantages of the sixth form of the invention should be
readily apparent to those skilled in the art. With regard to the
form of the invention, as seen in FIG. 21 and following, it will be
recognized that the same bracket base 601, including the coupling
portion 610, may be utilized for either, on the one hand, a
self-ligating bracket arrangement, as seen in FIG. 21, or further
an active self ligation bracket arrangement, as seen in FIG. 23.
The sixth form of the invention 600 further allows the same bracket
body insert 660 to be employed to affect either the use of the
bracket body with a passive self-ligating arrangement (FIG. 21), or
an active self-ligating arrangement (FIG. 23), or a conventional
tied bracket. This particular form of the invention is quite
desirable from a manufacturing standpoint inasmuch as the cost of
manufacturing is substantially reduced and provides a range of
passive and active self-ligating brackets, which may be useful in a
wide range of clinical settings in a manner not possible,
heretofore.
Operation
[0082] In its broadest aspect, the present invention relates to an
orthodontic bracket, which is generally indicated by the numeral
10, and which includes a bracket base 21, which is releasably
affixed to an anterior facing surface 12 of a patient's tooth 11.
The orthodontic bracket 10 further includes a bracket body 40,
which is borne on the bracket base 21, and which has an anterior
facing surface 42, which defines a transversely disposed arch wire
slot 60. The arch wire slot 60 further has opposite, first and
second ends 61 and 62, respectively. The arch wire slot 60 has a
selectively adjustable cross-sectional dimension, and further
includes a central region or portion which is generally indicated
by the numeral 66. As illustrated in the drawings, the arch wire
slot 60 is movable in both the vertical and horizontal planes, and
has a central region, as earlier described. Still further, the arch
wire slot 60 as noted above, has a selectively adjustable
cross-sectional dimension. Further, the orthodontic bracket 10
includes an arch wire 90, which is received within the transversely
disposed arch wire slot 60. The bracket body 40, acting in
combination with the arch wire 90, is selectively adjustable so as
to provide a multiplicity of selective torque expressions 13, 14
and 15, respectively, and which individually, forcibly act on the
patients tooth 11. These first, second and third orders of movement
of the patient's tooth occur without a clinically predetermined
manipulation of the arch wire 90, which is received in the
transversely disposed arch wire slot 60. Further, rotation of the
arch wire slot 60 in either of the vertical or horizontal planes is
maintained about the central region 66 of the arch wire slot 60.
This is a significant advancement in the way in which a clinician
can address orthodontic maladies inasmuch as the fine adjustment of
a tooth position can now be performed in a manner which
substantially prevents any adverse vertical movement component or
force vector being unduly applied to the patient's tooth 11.
[0083] More specifically, the present invention relates to an
orthodontic bracket which is generally indicated by the numeral
600, and which is seen in FIG. 21, and following. The orthodontic
bracket 600 includes a bracket base 601, having a pad 602, which is
releasably affixed to an anterior facing surface 12 of a patient's
tooth 11. The bracket base 601, as illustrated, has an anterior
facing surface 604, which defines a coupling portion 610. The
coupling portion further has a curved, anterior or upwardly facing
surface 614. As seen in the drawings, a multiplicity of engagement
regions 616 are formed in a predetermined spatial pattern in the
curved anterior facing surface 614 of the coupling portion 610. As
further illustrated in the drawings, a bracket body 620 is provided
and which matingly, and movably cooperates with the bracket base
601, and which further has an anterior facing surface 622 which
defines an aperture which communicates with an arch wire slot 640.
The arch wire slot 640 has spaced, top and bottom surfaces 641 and
642, respectively, and a given cross-sectional dimension. The
transversely disposed arch wire slot 640 communicates with the
aperture 629 which is defined by the anterior facing surface 622 of
the bracket body 620. Still further, the transversely disposed arch
wire slot 640 is further accessible from the anterior facing
surface 622 of the bracket body 620. The bracket body 620 has a
complimentary, curved, posterior facing surface 650, which matingly
and movably engages the curved anterior facing surface 614 of the
coupling portion 610 of the bracket base 601. The present invention
also includes a bracket body insert 660, which is releasably
received within the transversely disposed arch wire slot 640, and
which further has a main body 661, which forms a supporting back
wall 664 of the transversely disposed arch wire slot 640. The
supporting back wall 664 extends between the top and bottom
surfaces 641 and 642, respectively, of the arch wire slot 640. The
bracket body insert 660 further has a main body 661, which has a
predetermined length, height and thickness dimension. The bracket
body insert 660 selectively adjusts the cross-sectional dimension
of the transversely disposed arch wire slot 640. The bracket body
insert 660 further includes an elongated engagement member 670,
which is oriented substantially perpendicularly relative to the
main body 661 thereof, and which further has a distal end 671,
which is operable to be received in one of the engagement regions
616 that are formed in the bracket base 601 The engagement member
670 of the bracket body insert 660 is effective in selectively
fixing the rotatable orientation of the movable bracket body 620
relative to the bracket base 601. The orthodontic bracket 600
further includes an arch wire 628, which is received within the
transversely disposed arch wire slot 640. The movable bracket body
640, acting in combination with the bracket body insert 660,
selectively provides first, second and third order torque couples
13, 14 and 15, respectively, to a patient's tooth 11, to achieve a
clinically desired positional correction of the patient's tooth 11,
without the replacement of the orthodontic bracket base and/or the
arch wire 628 during a predetermined clinical treatment regimen.
Still further, the orthodontic bracket 600, in one form, and as
seen in FIG. 21, further includes a movable gate, which is
positioned on the anterior facing surface 622, of the bracket body
620, and which further selectively occludes the aperture 629, which
is defined by the anterior facing surface 622 of the bracket body
620. As seen in FIG. 23, and in an alternative possible variation
or form of the invention, an active self ligating bracket is shown,
and which does not include such a gate assembly. As will be
recognized from the drawings, the transversely disposed arch wire
slot 640 is movable in both the vertical and horizontal planes and
has a central region 645. As will be recognized, and as was
discussed earlier, during rotation of the arch wire slot 640, in
either the vertical nor horizontal planes, the arch wire slot is
substantially vertically maintained about the central region of the
arch wire slot 645, thereby providing numerous benefits to the
clinician which have not been available in other prior orthodontic
assemblies which have been utilized heretofore. The orthodontic
bracket 600, as seen, can achieve first, second and third orders of
movement of the patient's tooth 11 without a clinically
predetermined manipulation of the arch wire, and which is received
in the transversely disposed arch wire slot. These features, in
combination, are novel, and not found in a single prior art
reference known to the inventors named in this patent
application.
[0084] Therefore, it will be seen that the orthodontic bracket, in
its various forms, as shown, in the present application, provides
numerous means for readily, and easily treating a variety of
orthodontic maladies in a manner not possible, heretofore. The
present device is easy to employ; allows a clinician to use a
single arch wire for the vast majority of clinical applications;
allows a clinician to use lighter force arch wires, which provides
greater comfort for patients; and additionally allows clinicians to
rotate and move a patient's teeth in a manner which can achieve
superior results, in shorter treatment times, and with greatly
improved clinical results.
[0085] In compliance with the statute, the invention has been
described in language more or less specific as to structural and
methodical features. It is to be understood, however, that the
invention is not limited to the specific features shown and
described, since the means herein disclosed comprise preferred
forms of putting the invention into effect. The invention is,
therefore, claimed in any of its forms or modifications within the
proper scope of the appended claims appropriately interpreted in
accordance with the Doctrine of Equivalents.
