Abstract

The aughor has studied roentgenographic images of temporomandibular articulation using various conventional roentgenographies.
The roentgenographic images have obtained by application of the contrast media on the glenoid fossa and condylar head in human dry skull. comparing the various roentgenograms by Modified Transcranial projection, A-P T.M. articulatin projection, Reverse Towne projection, Mayer projection and Bregma-Menton projection.
The uthor has drawn following results.
1. The sharp radiogaphic details were obtained by all technics used except the Bregma-Menton projection, which seemed to be impractical to the sutdy of T.M.J. because of to be shortened the image of condylar head.
2. The best inage of the condyle-fossa relationship was appeared by Modified Transcranial projection and better image was acquired by Orbito-Ramus projection, but there were all inferior in Reverse Towne projection, mayer projection and Bregma-menton projection.
3. In all the above techniques, the radiographic images of condylar head were clear and were apperared to be the convex type in Modified Transcranial projection, the angled type in Orbito-Ramus and Reverse Town projection, the flat type in Mayer projection and the distorted angled type in Bregma-Menton projection.
4. The radiographic image of condylar head was shortened in Bregma-Menton projection only and was magnified somewhat in other projection.
