The invention is a removal plastic oral appliance which includes sensors for detecting the position of a patients tongue and mandible. Pressure sensors in the appliance itself detect tongue contact and pressure against the palate or the lower teeth against the upper teeth. The sensors are connected electronically to an electronic processor which interprets the information against one or more contra-indicated tongue or jaw positions or activities, and selects an appropriate response from a pre-selected range of responses. The electronic processor sends a signal to a stimulus electrode to cause the patient to stop the contra indicated tongue position, jaw position, or activity.

A performance enhancing and force absorbing mouthguard adapted to fit the upper teeth of the mouth of an athlete wherein the mouthguard is of a composite material. The first internal layer is a nonsoftenable flexible framework which will permit the mouthguard to hold its shape during fitting as well as to absorb and dissipate significant impact conveyed to the upper teeth. The framework includes hard, durable bite plate wedges which lower the condyle from the temporomandibular joint in a fulcrum action to place the lower jaw in an optimum condition preventing impingement upon the nerves and arteries as well as spacing the upper and lower teeth apart. Elastomeric traction pads are on the bottom of the mouthguard and are grippingly engaged by the posterior teeth of the lower jaw. The elastomeric pads extend forwardly to form an anterior impact brace on the front of the mouthguard. While the framework and traction pads are mechanically interlocked, a softenable material is placed over the mouthguard excepting the contact portions of the traction pads and anterior impact brace to encapsulate the mouthguard and to permit custom fitting.
