摘要
为研究髁突的运动度，用曲面断层张、闭口片对１４４例颞下颌关节紊乱综合征（ｔｅｍｐｏｒｏ－ｍａｎｄｉｂｕｌａｒｊｏｉｎｔｄｉｓｔｕｒｂａｎｃｅｓｙｎｄｒｏｍｅ，ＴＭＪＤＳ）患者的髁突与关节结节之间的位置关系进行分析。根据髁突与关节结节的关系及双侧运动是否一致将髁突的运动度分为６型，并对各型的性别与年龄组成、张口度与张口型、弹响与疼痛情况、病程及骨质改变进行了分析。结果说明下颌过大运动所造成的关节结构及下颌肌肉、韧带的急性损伤是产生ＴＭＪＤＳ的主要原因之一。
The abnormal movement of mandible is one of the three chief symptoms of TMJDS, it is described usually by the degree and type of mouth opening. We use close and open mouth position panoramic radiographs of 144 cases with TMJDS to observe the relationship between the head of condyle and the articular eminence. It can show the different degrees of movement of condyle and the degree of movement of both sides to see they are in balance or not. We classified the movement of the condyle in to six types, and measure the degree of mouth opening on the same film. The rela tionship between the result of them and the climnical symptoms are then analysed. We concluded that the supermovement of the condyle, which cause the acute and chronic trauma to the structures of TMJ and related muscles and ligaments, is one of the chief etiologic factors of TMJDS. The method and advantages of using panoramic radiography to observe movement of condyle are discussed.
