| Outline of Final Research Achievements |
In recent years, static finite element analysis has been performed using three-dimensional morphology and CT values obtained from dental cone-beam CT in the maxillofacial field. On the other hand, because mastication is in an unsteady state and loading conditions change with time, dynamic analysis is necessary. Therefore, in this study, we developed an image-based, large- and multi-scale dynamic analysis of the mandible in consideration of cancellous bone.
Based on the results, the utility of the analysis was established. It is expected that new findings will be obtained by dynamic analysis of the relationship between stress waves during mastication and growth and development, and the jaw bone morphology.
