Abstract

The author obtained 120 oblique-lateral transcranial radiograms by two projection methods from 30 subjects with clinically normal TMJ. The relative position of the condyle within the articular fossa and the quality of the radiographic images were compared in the standardized and individualized radiographic groups. The results were as follows: 1. The condylar position in the individualized radiographic group was more posterior than that in the standardized radiographic group (P<0.001). 2. The horizontal angle between the long axis of condyle and intermeatal line in the individualized group ranged from 0° to 31° (14.38°±7.55°), and the highest prevalence was found between 15 and 19° 3. The individualized group showed prominent radiopaque shadow of the anterior condylar border; the image detail was superior in the standardized group to that of the individualized group (P<0.05).
