Cephalometric laminagrams of T.M.J. under the mandibular movement were obtained “Sectograph”.
We researched the inclination on the condyle of the non-working side at the lateral movement.
At the lateral movement, the movement which the condyle of the non-working side was stipulated to the maximum eccentric position.
The subjects were one hundred temporomandibular joints of 50 adults with normal occlusion.
The results obtained were as follows.
1. The average of the horizontal condylar inclination at the lateral movement of the condylar top and center were between 45-47 degrees either mandibular lateral movement.
2. The correlation of the right and left side were not recognized at the small quantity of the lateral movement, but they were recognized strongly at the large quantity of the lateral movement.
3. Tendency of change in the translated inclination were divided four categories but, the condylar of the non-working side was engaged in bodily shift at the lateral movement.
