碩士 === 國立中央大學 === 機械工程研究所 === 95 === This study is based on the resonant frequency response to specify criteria for examining the defect severity in the bone of dental implant. Both the finite element analysis and the experimental modal analysis are applied to compare the differences between experiment and simulation. By reviewing relevant literatures, it is known that the design model is similar to the cantilever beam structure. Furthermore, the study applied the given formula to generalize a relation between resonant frequency response and model size. In this article, three modals were designed to test and verify whether the resonant frequency response is related to model defected depth. Then, we collated those data and defined a criterion to detect the defect bone depth with dental implant. The five detection steps include to defect the horizontal positions, to detect the entire defect, to detect the defect depth and quantity in vertical section, to detect the whole defect, and to analyze etc. In the end, we applied the method in the third model to verify its effectiveness.
