The purpose of the present study is to measure and analyze mandibular movements of temporomandibular dysfunctioned patients, who have an increasing tendency every year. And this study is trying for dental diagnoses and treatments of this patients.We have mainly conducted research on the measurements and analyses of mandibular movements of normal subjects in the past twenty years, and besides have obtained many interesting information through mandibular dysfunctioned patients. The many of this patients reveal to disoder of mandibular movements. This disoder of mandibular movements are reflected the cause of dysfunction and the alteration of that can easily understand the process of treatments.The many of this patients have pain and a little change of occlusion have an effect on the gnathostomatic system. Thus specifications of mandibular measuring apparatus must be non-contact, three dimensional measurement and high accuracy as application to everyday clinical treatment.As an accomplish … More ment of this study, the necessary conditions are as follows;1) mandibular movements are three dimensional movements and moreover at that time the head move, thus it is necessary to measure simultaneously each others the minimum three or more points of maxillary and mandibular movements.2) As the face and head containing maxilla and mandibula are complicated and minute movements, the measuring apparatus must be non-contact for understanding physiological movements.3) Occulusal heights of a little quantity (10 <mu> m) influence on the gnathostomatic system, especially chewing and tapping movements are very fast phenomenon, thus the recording of high speed and high accuracy are necessary for the measurement of mandibular movements.Selspot system is certainly satisfied with conditions of this sort. We have developed many softwares and a revised program of crookedness in cameras and sensors, for the purpose of improving softprogram of Selspot system as usual into our analyzing program of mandibular movement. Therefore, we have developed to apply to the measurements of articulator and subjects. Less

本研究的目的是测量和分析颞下颌关节功能障碍患者的下颌运动，有逐年增加的趋势。在过去的二十年里，我们主要对正常人下颌运动进行了测量和分析，并从下颌功能障碍患者中获得了许多有趣的信息。多数患者表现为下颌运动障碍。这种下颌运动障碍反映了功能障碍的原因和改变，可以很容易地了解治疗过程，许多患者有疼痛，咬合的微小变化会影响颌口系统。因此，下颌骨测量仪的技术指标必须是非接触式的、三维测量的、高精度的，才能应用于日常的临床治疗。 ...更多信息 研究的必要条件如下：1）下颌运动是三维运动，而且此时头部运动，因此需要同时测量上颌骨和下颌运动的最少三个或更多点。2）由于包含上颌骨和下颌骨的面部和头部是复杂和微小的运动，测量装置必须是非接触式的，以便理解生理运动。3）少量（10米）的掩蔽高度对颌口系统的影响，特别是咀嚼和敲击运动是非常快的现象<mu>，因此，下颌运动的测量需要高速度、高精度的记录，Selspot系统在这方面是完全可以满足的。为了将Selspot系统的软件程序改进为我们的下颌运动分析程序，我们开发了许多软件，并修改了摄像机和传感器的弯曲程序。因此，我们开发了适用于牙合架和受试者的测量。少
