Mouthpiece and method for producing the same
First Claim
1. A method for producing a mouthpiece comprising the steps of:
- preparing a thermoplastic elastic sheet material formed to be increased in thickness from one end to the other end, said elastic sheet material comprising an ethylene-vinyl acetate copolymer having a vinyl acetate content of from 12-33 wt %;
preparing a teeth impression cast of a user who is going to use a mouthpiece to be produced; and
pressing said teeth impression cast against said thermoplastic elastic sheet material in a softened state, in such a position so that the thicker portion of said thermoplastic sheet material is at the front teeth position, so as to transfer a shape of said teeth of said user onto said thermoplastic elastic sheet material to thereby obtain a mouthpiece which is set to be thicker at a portion corresponding to a front teeth position than at a portion corresponding to a molar teeth position.
