项目摘要

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.

正确诊断下颌运动和牙齿接触关系，必须掌握相关信息。在我们的项目中，进行了以下实验。在第一年中，开发了用于咬合平衡的软件程序，该程序是通过T-Scan系统（Tekscan，U。S. A.）本研究利用SGG/AS（Siemens，德国）下颌运动分析系统进行下颌运动的咬合诊断，从而实现了在IBM PC XT的CRT上显示上下牙的早期接触和下颌运动的可视化信息。在一项实验中，它成为可能显示的个人运动领域的牙齿闪烁在参考内Posselt的图尖交错位置。本研究所开发的一套完整的系统，可同时使用T-Scan系统与SGG/AS系统来显示咬合接触与下颌运动。然而，T-Scan中传感器框架的测量精度仅为1.25mm，建议与咬合纸同时使用进行咬合评估。
