ARCHWIRE ASSEMBLY WITH STOPS
Abstract
An archwire assembly comprises an archwire with a crimpable
sleeve adapted to slidably move along the archwire so as to be
positioned between two adjacent brackets of orthodontic braces. The
archwire assembly further includes a stop applied to the archwire
and adapted to limit the movement of the sleeve along the archwire.
The stop may include removable stops where the sleeve is movable
along the archwire between the stops. The removable stops may be
movable along the archwire with the application of a sufficient
force. The stop may also include a friction-creating substance
applied to either the sleeve or the archwire such that it takes a
sufficient force to move the sleeve along the archwire. The stop
may also include a partially crimped sleeve applied to the archwire
such that it takes a sufficient force to move the sleeve along the
archwire.

Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application is a divisional application of pending U.S.
patent application Ser. No. 11/566,395, which is a divisional
application of U.S. Pat. No. 7,160,106, issued on Jan. 9, 2007.
FIELD OF THE INVENTION
[0002] The invention relates to orthodontic devices, and more
particularly, to a device used in conjunction with archwires
employed in orthodontic procedures.
BACKGROUND OF THE INVENTION
[0003] Orthodontic treatment normally involves the application of
mechanical forces to urge improperly positioned teeth into correct
alignment. One common form of orthodontic treatment includes the
use of orthodontic brackets that are fixed to teeth such as by a
band around individual teeth or, perhaps more commonly, by adhering
the brackets directly to the teeth. A resilient curved archwire is
then seated in the archwire slots of the brackets. The archwires
are generally attached to the brackets by ligature wires or elastic
bands. In some cases, however, self-ligating brackets are used that
include a movable cover that selectively closes the labial side of
the archwire slot of the brackets. The movable cover is opened for
inserting the archwire and then closed for retaining the archwire
within the archwire slot. When a patient's teeth are incorrectly
leveled and aligned, the archwire elastically deforms to engage the
brackets, thereby introducing a force that urges the teeth to move
to the correct position over time.
[0004] A frequent problem observed during orthodontic treatment is
that the archwire tends to move mesially-distally relative to the
brackets. The archwire engaged with the bracket slots flexes under
forces applied in the oral environment, such as forces applied for
chewing and tongue, musculature actions, or orthodontic forces.
These unbalanced forces have a tendency to move the archwire
through the archwire slots of the brackets in a mesial-distal
direction. This movement may cause a free end of the archwire to
protrude from one of the brackets attached to the distalmost molars
and contact gum or cheek tissue. As a result of the movement, the
opposite free end of the archwire may also become disengaged from
the bracket that is mounted to the distalmost molar on the opposite
side of the mouth cavity. The contact leads to irritation of the
gum or cheek tissue. Self-ligating brackets by definition lack
structures, such as ligatures and elastic bands, that might limit
the mesial-distal movement. Therefore, the mesial-distal movement
of the archwire is more pronounced in both active and passive
self-ligating brackets.
[0005] Several conventional techniques are used to limit the
mesial-distal movement of the archwire in the bracket slots. One
such technique, for example, is to insert the archwire through a
crimpable sleeve, such as a small diameter tube, then position the
archwire within the archwire slots with the sleeve located between
two adjacent brackets. The sleeve is eventually secured to the
archwire at a fixed position by crimping the sleeve to the
archwire. The sleeve is configured such that the sleeve cannot pass
through or move beyond an archwire slot as the archwire moves in
the mesial-distal direction. In this manner, the maximum
mesial-distal movement of the archwire is limited to the distance
between the adjacent brackets. If the distance between adjacent
brackets is sufficiently small, then the free ends of the archwire
do not either become disengaged from the bracket or protrude from
the bracket for irritating gum or cheek tissue.
[0006] A major shortcoming of the conventional technique described
above is that the crimpable sleeve is mounted to the archwire in
the field, such as a doctor's office, and usually by the dentist or
a dental assistant. This field assembly process is often time
consuming and may prove frustrating. An archwire has a small
cross-sectional profile and a crimpable sleeve has a very small
passageway for threading the archwire through the sleeve. Because
of the small sizes, the sleeve is difficult to thread onto the
archwire. Moreover, during handling of the archwire, such as during
its installation into the patient's mouth, the sleeve often slides
off one free end of the archwire and onto the floor, or is possibly
lost into the patient's mouth. It is often difficult to find a
sleeve on the floor after it has fallen off the end of the
archwire.
[0007] There is thus a need for an improved archwire assembly that
eliminates the field assembly and further limits the movement of
the sleeve once positioned on the archwire.
SUMMARY OF THE INVENTION
[0008] The invention provides an improved archwire assembly without
the drawbacks of existing archwire orthodontic devices. In one
embodiment of the invention, the archwire assembly comprises an
archwire, a crimpable sleeve adapted to slidably move along the
archwire, and two removable stops positioned on opposed sides of
the sleeve and adapted to limit the movement of the sleeve along
the archwire. The removable stops may be placed adjacent the ends
of the sleeve to substantially prevent the sleeve from moving along
the archwire or may be placed adjacent to the ends of the archwire
to prevent the sleeve from falling off the archwire. Furthermore,
the removable stops may be movable along the length of the archwire
when exposed to a sufficient force, such as a force greater than
the weight of the sleeve. In this manner, the sleeve can be
repositioned along the archwire to properly position it between
adjacent brackets. The sleeve is eventually crimped to secure the
sleeve to the archwire at a fixed position and the removable stops
are then removed.
[0009] In another embodiment of the invention, the archwire
assembly includes an archwire, a crimpable sleeve adapted to
slidably move along the archwire, and a friction-creating substance
applied to either the crimpable sleeve or to the archwire and
adapted to limit movement of the sleeve along the archwire. The
friction-creating substance creates friction between the sleeve and
archwire such that it takes a sufficient force, such as a force
greater than the weight of the sleeve, to move the sleeve along the
archwire. Otherwise, the position of the sleeve remains stationary.
In this manner, the sleeve can be repositioned along the archwire
to properly position it between adjacent brackets. The sleeve is
eventually crimped to secure the sleeve to the archwire at a fixed
position. The friction-creating substance may be removable, such as
by being water soluble, and removed after the sleeve is secured to
the archwire.
[0010] In yet another embodiment of the invention, the archwire
assembly includes an archwire and a crimpable sleeve that has been
partially crimped so as to limit movement of the sleeve along the
archwire. The sleeve is crimped just enough such that it takes a
sufficient force, such as a force greater than the weight of the
sleeve, to move the sleeve along the archwire. Otherwise, the
position of the sleeve remains stationary. In this manner, the
sleeve can be repositioned along the archwire to properly position
it between adjacent brackets. The sleeve is eventually completely
crimped so as to secure the sleeve to the archwire at a fixed
position.
[0011] By virtue of the foregoing, there is thus provided an
archwire assembly that eliminates field assembly and further limits
movement of the crimpable sleeve along the archwire. These and
other advantages of the invention shall be made apparent from the
accompanying drawings and the description thereof.

DETAILED DESCRIPTION
[0027] With reference to FIGS. 1-2, orthodontic braces 10 are
provided or applied on the upper teeth 12 and lower teeth 14. The
braces 10 generally comprise brackets 16 typically adhered to the
upper and lower teeth 12, 14. Archwires 18, which may be formed of
NiTi alloys, Ti based alloys or stainless steel, are attached to
brackets 16 along archwire slots 20 by, for example, ligature wires
or elastic bands 22 or brackets 16 may be self-ligating. Braces 10
further include crimpable sleeves 24 positioned between adjacent
brackets 16. Once positioned between adjacent brackets, sleeves 24
are crimped to secure sleeves 24 to the archwire 18 at a fixed
position. Sleeves 24 are configured such that sleeves 24 cannot
slide past archwire slots 20 of brackets 16 when the archwire 18
moves in a mesial-distal direction. The mesial-distal movement of
the archwire 18 is then limited to the distance between adjacent
brackets 16. When sleeves 24 contact brackets 16, any further
movement of the archwire 18 is then prevented.
[0028] With reference to FIG. 3, an archwire assembly, shown
generally at 26, comprises an archwire 28 having a crimpable sleeve
30 applied in an uncrimped condition to archwire 28. The sleeve 30
is adapted to freely slide along the archwire 28 so as to be easily
positioned at desired locations along the archwire 28, such as
between a chosen pair of brackets 16 (FIG. 2). The archwire
assembly 26 further includes removable stops 32 applied to the
archwire 28 at opposed ends 34, 36 of sleeve 30 such that sleeve 30
is movable along the archwire 28 between removable stops 32. Stops
32 may be positioned immediately adjacent ends 34, 36 of sleeve 30
to substantially prevent sleeve 30 from moving along archwire 28.
Alternatively, stops 32 may be positioned adjacent the ends 38, 40
of archwire 28. Sleeve 30 is then free to slide along substantially
the entire length of archwire 28 but is prevented from sliding off
ends 38, 40 of archwire 28 due to stops 32. It is to be understood,
however, that stops 32 may be placed at any location along the
archwire 28 that bound sleeve 30 between stops 32. The archwire
assembly 26 may be pre-assembled and packaged for delivery to a
doctor's office with the sleeve 30 and stops 32 already mounted on
the archwire 28. This advantageously eliminates the frustrating and
time consuming field assembly required to apply the sleeve 30 onto
archwire 28 and limits its movement along archwire 28.
[0029] A wide range of removable stops 32 may be used in the
invention. For example, FIG. 3A shows a pair of elastic O-rings 42
on archwire 28 and bounding sleeve 30 between the O-rings 42. FIG.
3B shows a pair of removable stops in the form of slotted collars
44 having a hole 46 therein to engage archwire 28 and further
having a radial slot 48 such that stops 44 may be positioned on the
archwire 28 by sliding archwire 28 through the radial slot 48 and
into hole 46. Slotted collars 44 may be a resilient plastic
material that engages archwire 28 or may be metallic stops that are
crimped to engage archwire 28. FIG. 3C shows a spring loaded stop
50 comprising a spring 52 and arm 54 such that spring 52 engages
arm 54 against archwire 28. FIG. 3D shows an archwire 28 having a
sleeve 30 and further having discrete amounts 55 of a substance,
such as an organic material, a polymeric material or a wax,
situated at ends 38, 40 of archwire 28 that operate as removable
stops 32 so that sleeve 30 cannot come off ends 38, 40 of the
archwire 28.
[0030] It is to be understood that multiple sleeves and multiple
stops may be used in an archwire assembly. For instance, and as
shown in FIG. 3E, the archwire assembly 26 may have a second
crimpable sleeve 31 between stops 32. Additionally, a third stop 33
(shown in phantom) may be positioned between stops 30, 31.
Alternatively, an archwire assembly may provide several pre-applied
sleeves with stops located only at the ends of the archwire. Those
skilled in the art will recognize a wide range of configurations
possible with the invention.
[0031] Stops 32 may be advantageously movable along archwire 28.
This allows the dentist, or other clinician, to reposition sleeve
30 to a particular position along archwire 28 and then temporarily
fix the location of the sleeve with removable stops 32. This might
occur, for example, in positioning sleeve 30 between adjacent
brackets 16. Removable stops 32 that are movable, such as for
example, O-rings 42, slotted collars 44 and spring loaded stops 50
are adapted to move along archwire 28 only upon the application of
a large enough force. Otherwise, the position of removable stops 32
remains stationary. To prevent the unintentional movement of
removable stops 32 along archwire 28, the force required to move
removable stops 32 should be greater than the weight of sleeve 30.
For example, removable stops 32 may be adapted to move on the
application of a force of approximately one half pound. This
prevents the movement of removable stops 32 under the weight of
sleeve 30 but allows removable stops 32 to be easily repositioned
along archwire 28. Once sleeve 30 has been properly positioned
along archwire 28, such as between adjacent brackets 16, sleeve 30
is eventually crimped to secure sleeve 30 to archwire 28 at a fixed
position. Removable stops 32 are then removed from archwire 28.
[0032] With reference to FIGS. 4-6 and in another embodiment of the
invention, an archwire assembly 56 comprises an archwire 58 having
a crimpable sleeve 60 applied in an uncrimped condition to archwire
58. Archwire assembly 56 further includes a friction-creating
substance 62 adapted to limit movement of sleeve 60 along archwire
58. As shown in FIG. 4, the friction-creating substance 62 may be
applied to archwire 58 by either partially or completely coating
archwire 58. Alternatively, and as shown in FIG. 5, the friction
creating substance may be applied to the inside of sleeve 60, such
as for example, by partially or completely filling sleeve 60 with
the friction-creating substance 62.
[0033] In either case, and as shown in FIG. 6, the archwire
assembly 56 includes a friction-creating substance 62 between the
sleeve 60 and archwire 58. Sleeve 60, however, remains movable
along archwire 58 upon the application of a large enough force.
Otherwise, the position of sleeve 60 remains stationary. To prevent
the unintentional movement of sleeve 60 along archwire 58, the
force required to move sleeve 60 should be greater than the weight
of sleeve 60. For example, sleeve 60 may be adapted to move on the
application of a force of approximately one half pound. This
prevents the movement of sleeve 60 under its own weight but allows
sleeve 60 to be easily repositioned along archwire 58.
Additionally, archwire assembly 56 may further include removable
stops 64 as an additional feature to, for example, prevent sleeve
60 from coming off the archwire 58. The archwire assembly 56 may be
pre-assembled and packaged for delivery to a doctor's office with
the sleeve 60 and friction-creating substance 62 already on the
archwire 58 and/or sleeve 60. This advantageously eliminates the
frustrating and time consuming field assembly required to apply the
sleeve 60 onto archwire 58 and limits its movement along archwire
58.
[0034] A wide range of friction-creating substances 62 may be used
in the invention to increase the sliding resistance of the sleeve
60 along archwire 58. For example, the friction-creating substance
may be selected from waxes, sugar compounds, starches, elastomeric
materials, organic materials, and polymeric materials. Moreover,
these friction-creating materials may advantageously be removable,
such as by being water soluble. In this manner, after sleeve 60 is
properly positioned and crimped to secure sleeve 60 to archwire 58
in a fixed position, the removable friction-creating substance 62
may be removed by simply washing the archwire 58 or allowing the
patient=s saliva to remove the friction-creating substance 62 over
time.
[0035] FIG. 7 shows yet another embodiment of the invention. FIG. 7
shows an archwire assembly 66 comprising an archwire 68 having a
crimpable sleeve 70 partially crimped to limit movement of sleeve
70 along archwire 68. Although archwire assembly 66 includes a
partially crimped sleeve 70, the sleeve 70 remains movable along
archwire 68 upon the application of a large enough force.
Otherwise, the position of sleeve 70 remains stationary. To prevent
the unintentional movement of sleeve 70, the force required to move
sleeve 70 should be greater than the weight of sleeve 70. For
example, sleeve 70 may be adapted to move on the application of a
force of approximately one half pound. This prevents the movement
of sleeve 70 under its own weight but allows sleeve 70 to be easily
repositioned along archwire 68. In this manner, after partially
crimped sleeve 70 is properly positioned, sleeve 70 is completely
crimped to secure sleeve 70 to archwire 68 in a fixed position.
Additionally, archwire assembly 66 may further include removable
stops as an additional feature to, for example, prevent sleeve 70
from coming off the archwire 68. A friction-creating substance as
described above may also be used in combination with archwire 68
and sleeve 70. The archwire assembly 66 may be pre-assembled and
packaged for delivery to a doctor's office with the partially
crimped sleeve 70 already mounted on the archwire 68. This
advantageously eliminates the frustrating and time consuming field
assembly required to apply the sleeve 70 onto archwire 68 and
limits its movement along archwire 68.
[0036] With reference to FIGS. 8 and 9, an archwire assembly,
indicated generally by reference numeral 78, includes a pair of
crimpable sleeves 80, 82 each applied in an uncrimped condition to
archwire 28 (FIGS. 1-3). Each of the sleeves 80, 82, of which only
crimpable sleeve 80 is shown for purposes of description in FIG. 9,
features a ball hook 84 with a post 86 projecting from a tubular
body 88, a head 90 located at the free end of the post 86, and a
lumen 92, through which the archwire 28 is threaded, that is
slightly larger in diameter than archwire 28. The sleeves 80, 82
are positioned on the archwire 28 proximate to the free ends 38, 40
of the archwire 28 with the ball hook 84 on each sleeve 80, 82
remote from the corresponding free end 38, 40.
[0037] Each of the sleeves 80, 82 is coupled by a removable stop
94, in the form of an endless resilient or elastomeric band, with a
corresponding one of the free ends 38, 40 of archwire 28. The head
90 assists in securing the removable stop 94 to each ball hook 94
as the removable stop 94 is looped over the post 86. The elastic
force applied by the removable stop 94 to the ball hook 84 creates
a torque because the diameter of lumen 93 is larger than the
diameter than archwire 28, the elastic force is not parallel to the
centerline of the tubular body 88 but spaced radially by post 86,
and the ball hook 84 is off-center of the tubular body 88 in a
mesial-distal direction. The torque causes the tubular body 88 to
rotate, cock or cant relative to the archwire 28, in a direction
generally indicated by arrow 96, for securing the tubular body 88
to the archwire 28 in a temporarily position by a frictional
engagement between the tubular body 88 and the outer surface of the
archwire 28.
[0038] The archwire assembly 78 is pre-assembled and packaged for
delivery to a doctor's office with the sleeves 80, 82 already
mounted and self-locked by one of the removable stops 94 on the
archwire 28. The invention contemplates that the archwire assembly
78 may be positioned in association with the braces 10 on one or
both of the upper teeth 12 and the lower teeth 14. After the braces
10 are deployed in the patient=s mouth, the removable stops 94 are
removed to release the sleeves 80, 82. The sleeves 80, 82 are then
freely movable along the archwire 28 until crimped to establish a
fixed position. If at least one sleeve 80, 82 is crimped on the
braces 10 of the upper teeth 12 in, for example, the upper left
quadrant and on the braces 10 of the lower teeth 14 in, for
example, the lower left quadrant, a ligature or other resilient
member (not shown) may be used to interconnect the ball hooks 84
for applying an orthodontic correction or, alternatively, to
achieve intermaxillary fixation following orthognathic surgery. It
is contemplated that each of the sleeves 80, 82 may include other
types of attachments (not shown).
[0039] While the invention has been illustrated by the description
of embodiments thereof, and while the embodiments have been
described in considerable detail, it is not intended to restrict or
in any way limit the scope of the appended claims to such detail.
Additional advantages and modifications will readily appear to
those skilled in the art. The invention in its broader aspects is,
therefore, not limited to the specific details, representative
apparatus, and illustrative examples shown and described.
Accordingly, departures may be made from such details without
departing from the spirit or scope of the general inventive
concept.
