Abstract: The present invention provides an improved mouth guard (10) for braces having a U-shaped base portion (30) made from EVA or similar plastic having a melting point less than the boiling point of water, and an upper portion (20) extending generally upwardly from the outer perimeter of the base potion with an inner surface (21) made from PVC or similar material having a melting point greater than the boiling point of water, whereby a partially custom-fitted mouth guard is provided for users with braces.

Abstract: The present invention provides a hand shield (10) adapted for use with a hockey stick. The hand shield includes a flexible shield portion (11) having a convex outer surface (12) and an opening configured to accommodate a portion of a hockey stick. The hand shield further comprises an interior grip portion extending away from the shield portion and configured so as to slidably embrace a hockey stick. In one aspect, the interior grip portion includes four generally parallel flexible tabs (15, 16, 17, 19) which align with the four sides of a rectangular hockey stick.

Abstract: A mouthguard (10) has a U-shaped base (11) having an upper surface (16) and a lower surface (18). An inner wall (19) extends upwardly from an inner margin of the base upper surface. An outer wall (21) extends upwardly from an outer margin of the base upper surface. The inner and outer walls defined with the base upper surface a trough adapted to receive a person's upper teeth. The improvement comprises a recess (24) that extends into at least one of the inner wall and base proximate the wearer's front or incisor teeth, and extends between the base upper and lower surfaces. The recess is so positioned, configured and arranged as to enable the wearer to suck fluids from the trough through the recess when the mouthguard is installed such that the mouthguard will fit more closely then if such fluids were present in the trough.

Abstract: A tooth bleaching tray (20) broadly includes a U-shaped trough-like member (21) having a central arcuate portion (22) and having an extension portion (23, 24) continuing from either end thereof and terminating in a distal end (25, 26). The tray has an outer wall (28) adapted to face toward the outer surface of a person's teeth, an inner wall (29) adapted to face toward the inner surface of such person's teeth, and a bottom surface (30) joining the lower margins of the inner and outer walls. A thin flexible wall (31, 32) is located at each extension portion distal end (25, 26) and joins the margins of the inner and outer walls and the bottom surface. This flexible portion is adapted to conform to the shape of such person's rearwardmost molar without deformation of the trough-like member, and functions as a dam to prevent bleaching composition from flowing out of the trough-like member through the distal ends.
