| Outline of Final Research Achievements |
The finite element models of the skull with deviated occlusion were constructed using CT images, and then the loading conditions were set depending on the direction and cross sectional area of the masticatory muscles. As a result, the model showed imbalanced stress distribution in both maxilla and mandible. Furthermore, alveolar bones also showed imbalanced stress distribution. Then, to elucidate the effects of the treatment changes on the deviated occlusion, treatment models were created using the original deviated skull. The loading conditions were set based on the patient's original loading conditions. As a result, the imbalanced stress distribution was reduced in the maxilla. However, the imbalanced stress distribution showed little change in the mandibular body and alveolar bones.
These results of this study suggested that the loading conditions for the treatment model should be considered the changes of the masticatory muscles and surrounding tissues during the treatment.
