应用计算机轴位测量仪，对32例下颌关节盘移位患者下颌骨开合位时的水平平面内的髁状突轨迹进行了分析。开放时的水平髁状突痕迹可分为15种类型。各型与临床症状之间无明显关系。左右关节之间存在特定的类型对应关系。在32例患者中，21例患者一侧髁突偏向内侧，而对侧髁突在最大张开时偏向外侧。在大多数在最大开口处表现为内外侧偏斜的患者中，观察到从最大开口处到闭合滴答声前的位置有一条笔直的髁状突路径。在一些患者中，打开时的水平髁状突轨迹的类型与磁共振成像(MRI)评估的椎间盘移位模式有关。
In 32 patients with disk displacement with reduction, the condylar path in the horizontal plane during opening and closing movements of the mandible were analyzed with a computerized axiograph. The horizontal condylar tracings during opening were divided into 15 types. There was no clear relationship between the types and clinical symptoms. The specific correspondence of the types were revealed between the right and left joint. In 21 of 32 patients, the condyle on one side deviated medially, while the contralateral condyle deviated laterally at maximum opening. In most of the patients showing medio-lateral condylar deviation at maximum opening, a straight condylar path was observed from the maximum opening to the position just before the closing click. In some of the patients, the type of horizontal condylar tracing during opening was related to the displacement pattern of the disk assessed by magnetic resonance imaging (MRI).
