Abstract

The number of occlusal contact points and he occlusal relation were investigated in dental students who were selected on the basis of normal occlusion and normal function of stomatognathic system. Silicone-Black Bites obtained from fifty subjects were analyzed on their white models and occlusal contacts were traced on models directly. The results were as follows; 1. There was no evident difference in the number of occlusal contact points between right and left sides 2. In the retruded position the numbers of occlusal contact points were 5.96pm3.35 in the upper jaws and 6.12pm3.52 in the lower jaws. 3. In the retruded position no occlusal contact point was found on the central and lateral incisors of upper and lower jaws. 4. Occlusal contact points were found almost on second molars of upper and lower jaws in the retruded position.
