抄録

A six-degree-of-freedom jaw tracking digital device, TRIMET was developed. In total, eight small LEDs are set on upper and lower facebows which are attached to the buccal surfaces of the dental arches. The weight of a complete facebow for the upper and lower jaws is just 40 g. The motion of the LEDs is registered with six high-resolution linear CCD cameras set around the subject's head. The TRIMET is a no-contact measuring device that allows precise six-degree-of-freedom jaw tracking without fixation of head or jaws or causing intercuspal obstructions that could alter oral function. Using these outstanding features it was attempted to determine whether there is coordination between head and mandibular movements in normal subjects and in TMD patients. It was found that, during jaw tapping movements, the head and the lower jaw have a functional synergy characterized by opposite trajectories of the upper and lower incisor point traces ; the incidence of such coordination was lower in TMD patients. A rotation-like head movement was also found in the sagittal plane during tapping whose center was located above the cervical vertebrae region.
