Outline of Final Research Achievements

The number of patients with temporomandibular joint (TMJ) disorder has increased in recent years. In this study we explored the parameters for accurate imaging of the mandibular motion trajectory using MR dynamic imaging. Moreover, we clarified the relationship between the articular disc displacement and the mechanical condition using finite element method (FEM) analysis and mandibular trajectory data. As a result of functional MRI, brain functional differences between mild TMJ disorder group and control group were revealed.
