Abstract
It was clinically important to substitute the physiologic centric relation to the therapeutic position of the patients who needed the oral rehabilitation or occlusal treatment. There were several methods for recording the centric relation. One of the known methods was to use the gothic arch tracer. However the existing intraoral device was difficult to adjust the three dimensional angulation of the recording plate and recording stylus depending on the hinge movement arch of the individual. The purpose of this study was to develop new intraoral tracer which had adjustable stylus within hinge movement arch for the record of centric relation and to evaluate the clinical application of this device. The results were as follow; 1. A stylus of new developed intraoral tracer was so adjustable that the recording of mandibular positions could be reproducible within the hinge movement arc. 2. A record plate of new developed intraoral tracer was so adjustable to parallel with the occlusal plane that lateral recording of mandibular position was able to obtain stably. This study showed that new developed intraoral tracer allowed the determination of the treatment position which can be used in the full mouth rehabilitation and occlusal treatments.
