Abstract
The author obtained the transcranial-oblique lateral radiograms from 78 patients(26 male, 52 female) with temporomandibular dysfunction problem. And then, the author analyzed the dimensional changes of the TMJ space on centric occlusion, horizontal condylar movement and antero-posterior positional relationship of condyle to the articular eminence on 2.54㎝ mouth opening with clicking, TMJ pain and mouth opening limitation repectively, which were the symptoms of the temporomandibular joint pain dysfunction problem, and compared these data with control group. The results were as follows: 1. In centric occlusion, anterior and posterior TMJ space of experimental group was slightly lesser than those of the control group, also superior TMJ space of experimental group was significantly lesser than that of the control group. (p<0.01) 2. In 2.54㎝ mouth opening, the condylar horizontal movement and the antero-posterior positional relationship to the articular eminence were significantly lesser than those of the control group. (p<0.01) 3. Examined experimental group, the degree of condylar horizontal movement of affected ide was lesser than that of the normal side in 2.54㎝ mouth opening.
