摘要 |
The present invention relates to a bilayer mouthguard fabricated from a high impact thermoplastic polymer blend having the ability to absorb, attenuate, and dissipate shock forces and a method of fabricating a mouthguard. The present invention utilizes a polymer blend comprising ethylene vinyl acetate and a thermoplastic urethane. The bilayer mouthguard has a U-shape base and is defined by inner lingual and outer labial walls, a channel for receiving the upper jaw and teeth, cushion pads laying within the U-shape base, and in certain designs a transition support portion extending forward from the posterior cushion pads connecting with an anterior impact brace that extends into the outer labial wall.
