A Developmental Study of Occlusal Examination System

相关的信息是正确诊断下颌运动和牙齿接触关系的必要条件。在我们的项目中，进行了以下实验。第一年，通过T-Scan系统（Tekscan，美国）开发了咬合平衡的软件程序，并通过siroathograph analysis system（SGG/AS, Siemens，德国）开发了下颌运动的咬合诊断软件程序，从而可以显示上、下牙过早接触，也可以在IBM PCXT的CRT上进行下颌运动，以获得视觉信息。第二年，通过改进的接口开发T-Scan和SGG/AS的信息同时显示。在一个实验中，在Posselt的图形中，可以根据齿间位置显示牙齿闪烁的单个运动区域。作为结论，可以得出以下结论。我们开发了一个完整的系统，通过同时使用T-Scan系统和SGG/AS系统来显示咬合接触和下颌运动。但是，T-Scan中传感器框架的测量精度受限于1.25mm，建议与遮挡纸同时使用进行咬合评估。

Pertinent information is mandatory for correct diagnosis of mandibular movement and tooth contact relation. In our project, the following experiments were performed. During 1st year, developments of soft ware programs for a purpose of occlusal equilibration by means of T-Scan system(Tekscan, U. S. A.)and also for a purpose of occlusal diagnosis of mandibular movement by means of Sirognathograph Analyzing System(SGG/AS, Siemens, Germany), As a result, it became possible to display premature contacts in upper and lower teeth and also to do mandibular movement on CRT of IBM PCXT for visual information.During 2nd year, development of simultaneous displays of the informations both from T-Scan and SGG/AS through modified interface. In an experiment, it became possible to display the individual movement areas of tooth glinding in reference to intercuspal position within Posselt's figure. As a conclusion, the following statement can be made.A total system we developed, became to display the occlusal contacts and mandibular movement by simultaneous usage of T-Scan system and SGG/AS. However, the measuring accuracy of sensor frame in T-Scan is limited by 1.25mm, and the simultaneous usage with occlusion paper is suggested for occlusal evaluation.
