ABSTRACT:
The present invention provides an intraoral sensing device which generates a pressure change in cavities positioned between the upper and lower dental surfaces. This signal is used to provide a therapeutic apparatus and method for treatment of temporomandibular joint dysfunction and bruxism. An audible signal is generated to wake the patient from a nocturnal eqisode of abnormal jaw muscle activity. Control means are provided to establish a threshold value below which no audio signal is generated.
