초록

The purpose of this study was to investigate the effects of the posterior slope of articular eminence on internal derangement of temporomandibular joint. The author had taken transcranial oblique lateral projections of both TMJs in 30 normal subjects and 40 internal derangement patients who had 54 affected sides and 26 unaffected sides, and then analyzed the films. The results were as follows : In normal subjects, there was no significant difference between in the males and females, and between in the right and left sides. The posterior slope of articular eminence of affected sides in patients was stiffer than that of unaffected sides in patients and also stiffer than that of normal subjects. Therefore, the author concluded that stiffer posterior slope of articular eminence was, the more susceptibility to internal derangement would be.
