碩士 === 國立臺灣科技大學 === 機械工程系 === 96 === This thesis mainly fabricates an alveolus bone of two-material model to simulate the loading situation of the alveolus bone after implantation, and measures strain of the model under loading to verify the Finite Element Method analysis. According to the real alveolus bone which contains the cortical bone and the cancellous bone, we establish a two-material model. In the model 3M Z100 light curing was used to replace the cortical bone and quartz powder and epoxy were used to replace the cancellous bone. The material constants (Modulus of Elasticity and Poisson’s Ration) of the model were determined experimentally. An implant was installed in the model as well as an abutment and a crown to simulate a real oral implantation. The complete model under occlusion was simulated by FEM. At the surface of the real model of the selected points were bonded bi-axes strain gages. After the experiment, the measured axial strains which under occlusion were found agree well with those results from FEM.
