AN ORAL APPLIANCE FOR PROTECTING THE TEETH OF A USER

摘要

An oral appliance has a generally U shaped body with a channel for receiving an upper or lower arch so that the front portion receives the incisors and canine teeth of a user and the arms extend into the occlusal plane and receive the molars and premolars. The base member has an outer wall and a base which defines a non-mouldable section having at least one void formed therein. The inner wall is formed from a material that softens and is mouldable at a temperature below 100°C and is compatible with the thermoplastic elastomer of the base member. The inner wall member is joined to the base by chemical adhesion and there is provided a frame member having a generally U shaped body formed from a thermoplastic material that is rigid and non-mouldable at temperatures below about 100°C that is encased within the body.
