Recently there are many patients who complain of pain in the TMJs and in the head and neck muscles as well as of jaw movement disturbances. Some of these patients exhibit the occlusal interferences in the molar region on the balancing side of the dentitions. The causative mechanism of the occurrence of the occlusal interferences on the balancing side were surveyed in the 26 cases of TMJ patients with the occlusal interferences on the balancing side of the dentitions, who were treated effectively by the occlusal adjustment.The occlusal interferences on the balancing side have been shown only in the molar region, particularly in the farthest rearward teeth in the dentitions. The occlusal interferences on the balancing side were caused by the following factors : 1. The defect of continuity and the difference in level on the occlusal plane caused by the tooth malalignment. 2. The steepness of the curve of the occlusion. 3. The tooth malalignment was caused by the missing, the extrusion, and the tilting of the adjacent teeth, and by the malalignment of canines and premolars.
