Research Abstract

We focused on finite element method(FEM) to clarify biomechanical role of cancellous bone architecture. The precise FE-model contained trabecular bone structure was made from micro-CT images and we carried out 3D-FEM to visualize load transfer paths. In addition, we put in the data of alignment and texture of biological apatite(BAp) crystallites for jaw bone simulator, so we could demonstrate high-quality analysis with multi-sclae simulator.
