Developing of Condylar Traces of Kinematic Center Recording System
下颌髁突运动中心轨迹测量分析系统

Since condylar movement includes both translatory and rotatory components, each condylar reference point moves in different path. Therefore, the choice of condylar reference point is important for the interpretation of condylar movement traces. Kinematic center was originally suggested by Kohno. It's like a translating rotational center of the condyle disk complex in condylar movements. Its movement traces are mainly determined by the contour of the articular eminence, and independent of additional rotatory component of condylar movements. To date, commercial comdylar traces of kinematic center recording system if not available in market. There are rare explorations in this field. Therefore, the aim of this study was to develop condylar traces of kinematic center recording system. A condylar movement traces of kinematic center recording system has been developed with the combinations of computer graphic, mathematics and oral physiology. The movement traces of any point on the mandible can be reconstructed by this system. Furthmore, the kinematic center of condylar can be located and its traces can be analyzed by this system.
