Abstract

A dental guard and tray, includes a thermoplastic dental guard, and a generally rigid tray fittingly receiving the dental guard during heating and fitting of the dental guard to teeth of the user. The dental guard includes a pair of bite pads positionable below rear teeth of the user and a connection band that connects between the bite pads and is positionable behind upper or lower front teeth of the user. The rigid tray includes a pair of bite pad supports and a connecting arc, the bite pad supports each providing a planar depression or well for receiving one of the bite pads, the connecting arc spanning between the bite pads and having fingers located proximate a midpoint of the arc and configured to angle rearwardly and upwardly from the connecting arc so as to underlie and receive the band when the dental guard is received onto the tray.

Claims (8)

1 . A method of reforming a dental guard comprising the steps of:

(A) providing a thermoplastic dental guard having a pair of bite pads adapted to be positionable upon teeth of a user;

(B) providing a pair of bite pad supports configured to receive the pair of bite pads of the dental guard, wherein each of the pair of bite pad supports has a tooth occlusal contacting surface, a recessed well extending from the tooth occlusal contacting surface and configured to receive at least a portion of one of the pair of bite pads therein;

(C) warming the thermoplastic dental guard to a temperature wherein the thermoplastic dental guard is malleable, thereby forming a warm thermoplastic dental guard;

(D) positioning the warm thermoplastic dental guard upon select teeth of the user; and

(E) having the user bite down upon the warm thermoplastic dental guard and the pair of bite pad supports to a position wherein the user's teeth contact each tooth occlusal contacting surface to prevent the teeth from contacting the respective recessed well, thereby allowing a portion of the warm thermoplastic dental guard to pass between the user's teeth and the pair of bite pad supports and allowing another portion of the warm thermoplastic dental guard to remain within the recessed well to form a post-procedure grinding wall.

2 . The method of claim 1 wherein in step (B) the pair of bite pad supports are part of a tray that includes a connecting arc extending between the pair of bite pad supports, and at least one support member extending from the connecting arc, and wherein in step (D) the at least one support member is positioned to contact the front teeth of the user to aid in positioning the tray.

3 . The method of claim 1 wherein the recessed wells include a flat floor to from a flat surface on the corresponding bite pad.
