[Evaluation of the normal adults' condylar position in the fossa].
44 normal adults were strictly selected from 450 subjects. Fully corrected lateral tomograms and individual corrected transcranial radiograms were taken in the intercuspid position. The area and linear measurements of the joint space were performed with the aid of a computer. 70 TMJs of the fully corrected lateral tomograms were included in the present study. The measurements of joint space area showed that the normal condylar position is in the center of the fossa basically. However, obvious variations of the condylar position could be seen. Therefore, the concentric position was not the only normal physiological position of the condyle.
