ATHLETIC MOUTH PROTECTOR APPARATUS
Abstract
Apparatus for protecting the mouth area of athletes engaged in
contact sports. The apparatus includes a thermo-plastic base member
that is heated to receive a bite from the user whereby his dental
impressions are applied to such base member. The base member is
formed with breathing orifices. Plugs are removably disposed within
the breathing orifices to prevent collapse of such orifices while
the bite takes place.

Claims
I claim:
1. Athletic mouth protector apparatus, comprising:
a horizontal, generally U-shaped base member of thermo-plastic
flexible composition adapted to receive and retain dental
impressions consisting of a planar surface with vertically
extending buttress means;
a bridging member integral with the front portion of said base
member and extending forwardly thereof;
a vertical lip shield that curves rearwardly and is attached to the
front of said bridging member;
breathing orifice means extending from the mid-portion of said base
member forwardly through said bridging member and lip shield;
plug means of a material which is not thermo-plastic at the same
temperature range as the material of the U-shaped base member
snugly removably disposed within said breathing orifice means to
support said orifice means against collapse while said base member
is bitten so as to receive said dental impressions, with said plug
means being slidably removed from said orifice means after said
dental impressions have been formed; and
a helmet attachment strap attached to said lip shield and extending
forwardly thereof.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention:
The present invention relates to a dental appliance and more
particularly to an athletic mouth protector.
2. Description of the Prior Art:
Various types of athletic mouth protectors are known to the art.
The most effective of such protectors utilize a body formed of a
thermo-plastic flexible composition which is heated to a
temperature at which it can be bitten so as to receive and retain
dental impressions of the user. Such protectors are not formed with
breathing orifices since such orifices would be collapsed during
the taking of the dental impression. Typical protectors of this
type are shown in U. S. Pat. Nos. 2,705,492 and 3,124,129.
SUMMARY OF THE INVENTION
The athletic mouth protector apparatus of the present invention
permits the use of a thermo-plastic flexible base member which
receives and retains dental impressions, but is provided with
breathing orifice means. In order to prevent collapse of such
breathing orifices while the dental impressions are being made,
removable plugs are disposed within such orifices. After the dental
impressions have been made these plugs are removed so as to expose
the breathing orifices.

DESCRIPTION OF A PREFERRED EMBODIMENT
Referring to the drawings, a preferred form of athletic mouth
protector apparatus embodying the present invention includes a
generally U-shaped base member B that is adapted to receive and
retain dental impressions. A lip shield 12 of generally oval and
rearwardly curved configuration is connected to the base member B
by a bridging member 14. A conventional helmet attachment strap 16
extends forwardly of the bridging unit 14 and shield 12. A pair of
breathing orifices 18 and 20 extend from the mid-portion of the
base member B forwardly completely through the bridging member 14
and lip shield 12. In FIGS. 2-5, a pair of plugs 22 and 24 are
shown removably disposed within the breathing orifices 18 and
20.
More particularly, the base member B, lip shield 12, bridging
member 14 and strap 16 are preferably, though not necessarily, of
integral construction. Conveniently, the material from which these
parts are formed is a thermoplastic, flexible composition of a type
well-known to the art. By way of example, such compositions
includes polyvinyl chloride, polyvinyl acetate, ethylene vinyl
acetate, polyvinyl butyral, vinyl alkyld, polyvinyl formal,
vinylidene chloride, polyvinyl acetol, vinyl stearate, polyvinyl
alcohol, vinyl paraffins and mixtures of these various types of
synthetic plastics. The plastic chosen will be colored in any
well-known manner and compounded to the proper hardness.
The base member B has an upper dental impression - receiving
surface 26 and a lower dental impression-receiving surface 28.
Upper and lower tooth buttresses 30 and 32 may be integrally formed
along the inner periphery of these surfaces. The breathing orifices
18 and 20 are mirror images of one another and should be of
sufficient size to permit normal breathing when the user of the
mouth protector has his teeth engaged with the upper and lower
surfaces 26 and 28 during athletic endeavors. The plugs 22 and 24
are of like construction and may be formed of any material which is
not thermo-plastic at the same temperature range at which the base
member B is thermo-plastic. Various suitable synthetic plastics may
be used to form the plugs. The plugs should have a snug sliding
engagement within their respective breathing orifices. The plugs 22
and 24 will be positioned within their respective breathing
orifices 18 and 20 before the dental impressions are made in the
upper and lower surfaces 26 and 28 of the base member B, as
indicated in FIGS. 2-5.
To form the dental impressions the base member B is heated in any
suitable manner for a time sufficient to render the material from
which base member B is made thermo-plastic and yet not so hot as to
burn the mouth of the user. Conveniently, this heating may be
accomplished by supporting the base member B within a body of
boiling water 40, as indicated in FIG. 4. The strap 16 affords a
convenient handle for holding the base member B during this
operation. When the base member B has become properly
thermo-plastic, it is removed from the water 40 and inserted into
the mouth of the user of the mouth protector. Such user then bites
against the upper and lower surfaces 26 and 28 of base member B, as
indicated in FIG. 5. This will serve to form dental impressions in
the upper and lower portions of the base member 10 corresponding to
the tooth configuration of the user. It is important to note that
the plugs 22 and 24 prevent collapse of the breathing orifices 18
and 20 as the base member is receiving the user's bite. After the
dental impressions have been made, plugs 22 and 24 will be
withdrawn from their respective breathing orifices and the mouth
protector will have the appearance shown in FIG. 6. Referring
thereto it will be seen that the dental impressions 42 have been
taken and the plugs 22 and 24 removed. The mouth protecor is then
utilized in a conventional manner by the athlete.
Various modifications and changes may be made with respect to the
foregoing detailed description without departing from the spirit of
the invention.
