Multiple sensors in an extremely light weight (four ounce) spectacle-like array, track the motion of a tiny magnet attached to the lower incisal gingiva with adhesive material. The configuration is totally non-invasive and, unlike clutches, does not interfere with patient function. The opposing sensors are wide apart permitting unobstructed access to the oral cavity for taking bite registrations and other clinical procedures, and the system is virtually immune from effects of slight head motion or nearby metallic or electronic interference. A patient education mode is included to simplify patient understanding and staff training.
An assembly of mains electricity (AC-powered) devices designed to record parameters for mandibular and muscles of mastication function, primarily to aid in the diagnosis and treatment of temperomandibular joint (TMJ) and myofascial pain dysfunction (MPD) disorders, and for orthodontic, denture, and reconstruction patient evaluation. It typically uses surface electromyography to evaluate muscle groups at rest or in function; sonography to detect sounds/vibrations from the TMJ joint and/or other computer-based system to non-invasively track the mandible in function or identify its position in space relative to the skull.
