We measured the mandibular displacement by the jaw tracking machine with six degree of freedom (MMJI-II ; SHOFU Co.) and occlusal force by thin force sensitive films with computerized analyzing system at the same time (Occiuser ; Fuji Co.).We tried to analyze how the decision making to the prosthetic intervention whether to proceed prosthetic treatment or not in the partially loss of posterior teeth in premolar and molar region in the form of distal extension denture or shortened dental arch (SDA) without prosthesis.Our decision making were consisted of two parts: first one was the subjective assessment by the patients with verbal inspections, direct inquiry about the loss of posterior teeth, second one was the objective assessment by the inspectors with oral examinations, comparative analysis of the condylar morphology in the edentulous and dentulous side by the three dimensional X-ray micro tomography and newly developed light weight jaw tracking machine with six-degree of freedom.We conducted a pilot analytical methods to diagnose whether man should proceed into the prosthetic treatment or not, taking strategy in the shortened dental arch concept according to the data obtained in this study.

采用六自由度下颌运动跟踪仪（MMJI-II ; SHOFU Co.）同时用薄力敏片和计算机分析系统（Occiuser ; Fuji Co.）测定咬合力。本文分析了前磨牙和磨牙区后牙部分缺失患者在无修复体的情况下，是否进行修复治疗的决策过程，包括两个部分：第一种是患者的主观评估，包括口头检查，直接询问后牙缺失情况，二是检查员通过口试进行客观评价，应用三维X线微断层扫描技术和新研制的轻型下颌骨跟踪仪对无牙侧和有牙侧髁突形态进行了对比分析。我们进行了一个试点的分析方法，以诊断人是否应该进行修复治疗或不，根据本研究中获得的数据，在缩短牙弓的概念采取战略。
