A Developmental Study for Occlusal Diagnosis System in Reference to Intercuspal Position

所获得的有关下颌和髁突运动功能评估的相关信息不仅对口腔生理和功能障碍的检查和诊断有用，而且适用于假体矫治器的构建。因此，我系在过去几年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，资助方式如下：1: 1987-1988（普通研究B）课题编号：62480399,2:1990-1991（普通研究C）课题编号：02670879,3:1989（推广研究A），课题编号：01771683,4:1993（推广研究A）课题编号：05771744。本研究是对上述课题的继续研究，目的是阐明由下颌和髁突运动产生的前路引导信息和后路引导信息的相关性。因此，三个主要的…更多的研究进行如下。HR型SGG分析系统的开发。先前的系统III可以三维显示牙齿滑动表面，但由于磁铁附着在受试者下门牙上的特点，也会产生一些畸变。初步研究表明，新型传感器具有更好的稳定性和改进的传感器框架，以减少齿面滑动变形。CADIAX系统的基础研究。CADIAX可以记录髁突的三维运动，有助于客观评估口颌系统的功能诊断。然而，实际上没有与CADIAX系统相关的计算机Axiograph测量精度的信息。实验结果表明：1 .电子旗的测量精度随位置的不同而变化，其测量值在3mm范围内近似可得；2 .电子针在0.07mm范围内，无论收缩程度如何，其测量精度都是均匀的。本研究使信号分析系统作为前导信息与CADIAX系统作为后导信息的应用相结合成为可能。少

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.
