Outline of Final Research Achievements

We investigated data calibration method for jaw tracking device. The primary coil unit (transmitter) and the secondary coil unit (sensor) were set 100mm apart from each other. The sensor was fixed at the 125 locations (10mm grids throughout the calibration volume (40x40x40mm)), and the positions of the sensor were recorded for 1 sec at 100 Hz. The calibration study revealed that the absolute position were 9.92+/-0.05mm for x-direction, 9.91+/-0.03mm for y-direction, and 9.93+/-0.03 mm for z-direction, respectively. Our jaw tracking device could allow to record jaw movement with sufficient accuracy. Regarding the registration between the coordinate system of the CT image and that of the jaw tracking device, we developed new registration technique that was used very small metal spheres (diameter: 0.4mm). Furthermore, we developed a software to automatically detect and classify bruxism events during awake and sleep based on jaw movement and masseter muscle activity patterns.
