  • Direct-formed mouthguard, a blank for use in making the mouthguard and a method of making the mouthguard
    Patent number: 5031638
    Abstract: A direct-formed mouthguard is provided. The mouthguard is formed from a blank which includes an inner layer, a rigid core disposed adjacent to and coextensively with the inner layer and an outer layer disposed adjacent to and coextensively with the core. Impressions of the user's intra-oral structures are made in the inner and outer layers by heating the blank to a predetermined temperature range and subjecting the blank to bite pressure. The impressions are set and the finished mouthguard is formed by cooling the blank below the predetermined temperature range. The core is formed from a material having a softening temperature above the predetermined temperature range and therefore provides structural support for the inner and outer layers when the blank is heated to the predetermined temperature range and after the blank is cooled to form the finished mouthguard.
