ABSTRACT:
A molded mouthguard is shaped in the configuration of a maxillary arch. The mouthguard includes a trough which is channel shaped in transverse cross section and a moldable upper fill which extends higher than the channel at least at the front, rear and buccal walls of the trough. The fill comprises a low softening temperature thermoplastic such as a suitable EVA and the trough is formed of a higher softening temperature thermoplastic. The mouthguard is suitable for do-it-yourself custom molding and is heated by emersion in water to a glass transition temperature which is below boiling temperature, e.g. within a range of 140.degree. F. to 180.degree. F., for approximately two minutes. The mouthguard is then inserted into the mouth, and centered against the teeth of the maxillary arch. The user then bites, causing the fill to extrude over the labial and buccal front, sides and rear of the trough as the fill conforms to the impression of the upper teeth. The extruded fill is forced against the gums and pallet for added protection and retention of the mouthguard.
