Abstract:
It is the purpose of this article to determine various normal anatomic measurements of temporomandibular joint and normal range of condylar movement using relatively simple X-ray equipment and radiographic technique in consideration of popular clinical application. Author's cases condisted of 100 clinically normal adult males and temporomandibular joint radiographs of 3 serial position so condylar head were taken by transcranial obliquelateral pojection in each case. The serial positions are centric occlusion, 1 inch opening and maximal opening position. The results were as follows; 1. In cetric occlusion, the length between the condylar head and glenoidfossa was 2.23±0.58mm in anterior part, 3.55±0.80mm in upper part and 2.76±0.72mm in posterior part. 2. Incentric occlusion, the angle (alpha) between the horizontal standard line(AB) and anterior slope (BC) was 37.22±3.87 degrees. 3. In 1 inch opening position, the distance between the summit of condylar head from thestandard point of articular eminence (B) was
