| Outline of Final Research Achievements |
This study was planned to visualize and quantitatively analyze the functional load of masticatory muscles and temporomandibular joint. However, the masticatory activities were analyzed under the various scclusal support conditions with the total muscle T2 shift as a new index using a novel bite force gauge, due to the problem in the MR imaging of temporomandibular joint.
The novel bite force gauge provided reliable real-time measurements of the bite force in the strong magnetic field of an MRI scanner. The index of total muscle activity was found to be a stronger correlation than the traditional index to the real bite force in the inter-subject study.
