Abstract:
During ideal physiologic occlusion in the intercuspal position, all molars are occluded simultaneously and each occlusal contact evenly transmits similar pressure. The purpose of this study is to analyze the occlusion in the mandibular bone fracture patients treated by open reduction. This patients were selected according to the following criteria: 1) complete dentition without any missing teeth, 2) relatively normal occlusion without original TMJ disorder. Occlusal analysis using T-scan system were performed in 22 patients and 20 normal subjects. Our results were followed: 1. The number of occlusal contacts and the magnitude or occlusal force were increased with time. (p<0.05). 2. In the unilateral mandibular fracture patients, occlusal force and occlusal contacts were increased with time on the both sides. 3. There was significant difference in the number of occlusal contacts and occlusal force between postoperative 1 month and normal group(P<0.05), but there was no significant difference in the number of occlusal contacts and occlusal force between postoperative 6 month and normal group(p>0.05).
