Abstract
The objective of this study was to compare the condylar path and the anterior angle of articular fossa and to analyze the pattern of condylar path in edentulus patients. Nineteen male and female edentulous patients with normal masticatory system ranging in age 42 to 78, without present symptoms and any history of TMJ disturbance were selected for this study. On the computer analysis on the transcranial radiographs of the TMJ, the angle of slope of articular eminance and condylar path to the Frankfort Horizontal Plane and the height of glenoid fossa was measured respectively, and stuied their
interrelationship comparatively. @ES Obtained results were asfollows: @EN 1. The angle of the slope of articular eminence averaged 37.28 degree, and there was no significant difference between the right and left side. 2. The condylar path angle averaged 29.05 degree and there was no significant difference between the right and left side. 3. The height of the glenoid fossa averaged 8.11 mm and there was no significant difference between the right and left side. 4. The sequence of the frequency of condylar movement patterns were concavex curve(39.5%). "S" shape curve(34.2%), reverse "S" shape(15.8%) and convex curve(10.5%) 5. The horizontal distance of the point of the changed curve of the condylar path averaged 2.91 mm. 6. The height of glenoid fossa was highly correlated to the slope of articular eminence and relatively highly correlated to the condylar path and the condylar path was closely correlated to the slop of articular eminence.
