Outline of Final Research Achievements |
We investigated the development of an objective evaluation method for comfortable occlusion and mastication by analyzing jaw movements. The jaw movements in six degrees of freedom and masticatory muscle activities were recorded simultaneously. At the start of the burst activity of the masseter muscle on the working side during biting on the dental stopping, the working kinematic condylar point reached its rearmost position significantly before the balancing kinematic condylar point reached its intercuspal position. At the peak of the burst, both kinematic condylar points reached their intercuspal positions more closely, however, the balancing kinematic condylar point reached a more superior position than its intercuspal position. At the peak of the burst during all chewing periods of a piece of bread, the working kinematic condylar points reached their intercuspal positions more closely, compared with at the start of burst activity of the working masseter muscle.
