    Abstract: 對於牙科植體骨整合檢測,本研究延續非接觸式電磁激振感應的方法於人工植牙手
    驗設計及流程,並且與市售檢測裝置Osstell® ISQ 及電容式位移計量測植體的共振頻率
    效果。;For dental implant osseointegration detection, this study continues a non-contact
    electromagnetic excitation in artificial implant surgery stable detection. Electromagnetic (EM)
    detection is used of interactive changing current signal, which input the inductor, and produce
    an interactive electromagnetic force to excite structures. Then linear Hall-effect sensor detects
    the resonance frequency (RF) of the dental implant structure. The thesis consists of two parts.
    First, the principle of inductive excitation source, selection criteria, the principle of Hall-effect
    sensors, and the schema electromagnetic detection device are briefly introduced. Then EM
    device will be fed with Morlet wavelet to verify the feasibility of the electromagnetic device.
    The second section describes in-vitro experimental processes, and the RF results obtained from
    measurement will be compared with Osstell® ISQ, and capacitive displacement sensor.
    Natural frequency depends on stiffness, and is affected by mass. If mass increases more
    than stiffness, natural frequency of the 1st mode shape decreases. Therefore, although the
    stiffness of structural bone blocks are increased by enlarging thickness of cortical bone, the
    RFs decreased. Increasing the Young’s modulus of cencellous bone will increase the structural
    stiffness. In order to correspond the clinical condition, bone block is attached the cortical shell
    in Buccal Lingual (BL) direction, it can increase the stiffness of bone block. As the thickness
    of cortical shell increase, RF is more difficult to measure. The results show that the
    non-contact electromagnetic detection device is reliable, but still need improvement to make
    the device more compact. Moreover, in-vivo experimental of animal- tibia is required to verify
    the devices applied in clinical condition.
