A Developmental Study of Occlusal Examination System

为了正确诊断下颌运动和牙齿接触关系，必须提供相关信息。在我们的项目中，进行了以下实验。在第一年，通过T-SCAN系统(美国Tekcan)开发了用于咬合平衡的软件程序，并通过Sirognathograph分析系统(SGG/AS，德国西门子)开发了用于下颌运动咬合诊断的软件程序，因此，有可能在IBM PCXT的CRT上显示上、下牙的早熟接触，并在CRT上进行下颌运动的视觉信息。第二年，通过改进的界面，同时显示T-SCAN和SGG/AS的信息。在一项实验中，可以根据波塞尔特图形中的牙尖间隙位置来显示牙齿闪烁的各个运动区。综上所述，我们开发了一套完整的系统，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。然而，T型扫描传感器框架的测量精度受限于1.25 mm，建议与咬合纸联用来评估咬合情况。

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.
