ABSTRACT:
The mouth and cheek protector is designed for use by persons undergoing orthodontal or orthognathic procedures requiring braces on the teeth. The protector consists of a thin strip of sponge-like cellular material formed to fit into the mouth and lie between the braces and the line of joinder between the gum and inner cheek. The cells of the sponge-like material have a generally uniform diameter of from 1/64th to 1/32nd of an inch. The major portion of the strip is approximately 1/8th of an inch thick with its opposite ends tapered to a thickness of 1/16th of an inch. One edge of the strip is straight and the opposite ends of the other edge are curved. The height of the strip is approximately 3/8ths of an inch and its length varies from one to two inches. In use, the curved edge of one or more of the strips rests against the braces and the straight edge lies close to and parallel with the line of joinder between the gum and inner cheek.
