Classification of disk configuration for 96 joints (89 patients) of internal derangement with closed lock of the temporomandibular joint was performed by means of double-spacing contrast arthrotomography. The results of the classification were presented in the first report of this series. The disk shape was divided into 3 types; the first type-prolonged shape maintaining the main parts of the disk, the second type-folded disk, and the third type-massed disk. In this article, the authors tried to clarify the correlation of disk configuration with the duration of illness and with the interincisal opening distance at the first presentation. In the results, the average duration of clicking and locking was statistically longer in the joints of the third type. The interincisal opening distance was statistically smaller in the joints of the first type. These results indicate that the severity of the disk deformation is closely related to the duration of illness and to the joint function.
采用双重间距对比关节造影术对96个关节（89例患者）的颞下颌关节内紊乱伴闭锁进行盘状结构分类。分类结果在本系列的第一篇报告中呈现。盘状形态分为3种类型：第一种为保持盘主要部分的延长型，第二种为折叠盘型，第三种为团块状盘型。在本文中，作者试图阐明盘状结构与病程以及首次就诊时切牙间开口距离之间的相关性。结果显示，第三型关节中弹响和闭锁的平均病程在统计学上更长。第一型关节的切牙间开口距离在统计学上更小。这些结果表明，盘状变形的严重程度与病程以及关节功能密切相关。
