The pertinent informations obtained for functional evaluation of the mnadibular and condylar movements are not only useful for examination and diagnosis of stomatognathic physiology and dysfunction but also applicabable to the construction of prosthetic appliances. Therefore, our department has been conducted in this primary subject during past years and these studies were supported by Grant-in-Aids from Ministry of Education, Science and Culture of Japan as in the following manner ; 1 : 1987-1988 (General Study B) Subject No.62480399,2 : 1990-1991 (General Study C) Subject No.02670879,3 : 1989 (Promotion Study A), Subject No.01771683,4 : 1993 (Promotion Study A) Subject No.05771744.Present study is a continued research project from above subjects and it's objective is to clarify the correlation of informations from the Sirognathograph Analyzing System for anterior guidance, whereas CADIAX for posterior guidance resulting from mandibular and condylar movements. Consequently, three majo … More r studies were conducted as follows.1. Developement of SGG Analyzing System with HR type.Previous system III could be displayd tooth gliding surfaces in three dimensionally, but some distortions were also occured due to the characteristics of magnet attached to subjects lower incisors. Pilot study proved that a new type HR showed better stability and improved sensor frame in order to reduce the distortions on the tooth gliding surfaces.2. Fundamental study of CADIAX system.CADIAX makes it possible record the three dimentional movements of condyles which contribute to the objective assesment for functional diagnosis in stomatognathic system. However, there were practically no informations on the measurement accuracy of the computerized Axiograph related to CADIAX system.Our experiments conclude 1 : Measurement accuracy of the electronic flag varied depending on its site and its values were recouded approximately within 3mm. 2 : Measurement accuracy of the electronic stylus was homogenous regardless of the degree of contraction within 0.07mm.3 : Establishment of Occlusal Diagnosis System.Present study made possible to connect the application of Sirognathograph Analyzing System and as anterior guidance information, and CADIAX system as posterior guidance one.

所获得的有关下颌和髁突运动的功能评价信息，不仅对口腔颌面生理和功能障碍的检查和诊断有重要意义，而且可用于修复体的制作。因此，我们部门在过去几年中一直在进行这一主要课题的研究，这些研究得到了日本文部科学省的资助，具体方式如下：1：1987-1988（一般研究B）受试者编号62480399，2：1990-1991（一般研究C）受试者编号02670879，3：1989（推广研究A），受试者编号01771683.4：1993（推广研究A）课题编号05771744本研究是上述课题的延续性研究，目的是阐明信息的相关性从Sirognathograph分析系统用于前引导，而CADIAX用于由下颌和髁突运动引起的后引导。因此，三大 ...更多信息 研究内容如下：1. HR型SGG分析系统的研制以前的系统Ⅲ能三维显示牙齿滑动面，但由于受试者下切牙上附着磁体的特点，也会产生一定的失真。初步研究证明，新型HR具有更好的稳定性，并改进了传感器框架，以减少齿面的变形. CADIAX系统的基础研究：CADIAX系统能够记录髁突的三维运动，为口颌系统功能诊断提供客观的评价。实验结果表明：（1）电子旗的测量精度随其位置的不同而变化，其测量值的误差在3 mm以内;第二章：3.咬合诊断系统的建立本研究将Sirognathograph分析系统作为前牙引导信息，将CADIAX系统作为后牙引导信息，两者的结合应用成为可能。少
