Description
Summary:碩士 === 國立臺灣科技大學 === 機械工程系 === 95 === In order to increase the probability of successful oral implantation computer simulation can be employed to analyze the loading situation of the alveolus bone after implantation. Finite Element Method is the most important computer software used to analyze the stress distribution over the alveolus under occlusion. However, during the FEM analysis, many conditions are simplified, the outcome of the analysis is needed to be verified by some experimental works. In this thesis, the alveolus bone was approached as a two-material model. The simulation model was fabricated by using various compositions of quartz powder and resin. The material constants (Modulus of Elasticity and Poisson’s Ration) of the model were determined experimentally. An implant was put 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 which had maximum stress was bonded a bi-axes strain gage. After the experiment, the measured strains were found agree well with those results from FEM.
