Method and apparatus for sensing and treating bruxism

摘要

An intraoral acrylic splint having incorporated into the interior of the splint a strip of piezoelectric film which emits a small electrical current when deformed by the compression of the teeth. The piezoelectric film is connected by conductors to a small battery powered radio transmitter contained in the splint. The transmitter generates and broadcasts a radio frequency signal when current is received from the piezoelectric film. The radio frequency signal is received by a remote receiver unit. The receiver unit emits an audible alarm upon receiving a signal from the radio transmitter of the splint. The audible alarm alerts the patient of his action, allowing him to consciously resist bruxing.
