Outline of Final Research Achievements

Square mandible (Masticatory muscle tendon-aponeurosis hyperplasia:MMTAH)is characterized by painless limitation of mouth opening and square mandible configuration. We have clinically applied the 4-dimentional muscle model to explore the pathology of MMTAH.
In this study, we examined the relationship of the stress distribution of the mandibular body with the pathology of MMTAH. Concretely, it was analyzed by integration of the data of the patients’ mandibular movements into the individual finite element model reconstructed using the patients’ CT data. As a result, the maximum stress was concentrated on the coronoid process and the mandibular angle during mouth opening and mouth closing in the MMTAH patients. It is interesting to note that the portion of stress concentration was in accordance with that of the mandibular hyperplasia in the MMTAH patients.
