We have developed a jaw tracking system with wireless resonated markers. The system consists of two resonated markers, driving coil, 40 pickup coils, DA converter, and AD converters. The two resonated markers were composed of a coil with NiZn ferrite and tip condenser. We attached to one marker on the incisor and the other on the forehead. Position accuracy of within 1 mm was achieved when the fabricated jaw model was moved about 40 mm. This system is available for tracking of reasonable jaw movement of normal subjects without disturbing the physiology.
