dc.description.abstract本論文針對牙科植體術後骨整合程度差異,所造成不同骨缺損型態,發展非侵入式檢測評估技術,探討並定量植體/齒槽骨之骨整合與植牙結構特性之關聯。透過所發展測量技術,期能改善臨床常用X光二維影像判讀之不足與僅以量測結構共振頻率呈現整體現象之限制,協助醫生監測病患植體與齒槽骨之整合情形,以提高植牙的成功率。為建立相關檢測評估技術,研究中設計兩類植牙放大實驗模型,進行實驗模態測試和有限元素模態分析,相互驗證並歸納結構共振頻率和骨整合狀態之關係。從研究中獲知,植體裸露無包覆時,其頻率為最低;隨著模型包覆高度的減少,結構共振頻率出現降低趨勢,此說明骨缺損會影響植體/齒槽骨結構,降低植體穩固度,由於剛性較小,以致結構共振頻率降低。為有助進行後續臨床研究,進行不規則骨缺損實驗及利用等比例條件進行植牙模擬分析,並提出後續研究方法。zh_TW
dc.description.abstractThis thesis aims at developing a technique to detect the differences of osseointergration on dental implants after surgery. Different osseointegration conditions cause variant bone defects. The developed noninvasive test distinguishes structure variations between implant/alveolus and osseointegration. Then, it makes the fixation quality analysis to create a measurement method, helps doctors monitor the developed implant conditions of patients and increases the success of embedding teeth. Therefore, this study designs two amplified experimental models to proceed the experimental modal testing and the finite element modal analysis. It induces the mutually relation of resonance frequency and mode shape. As a result, implants no coating and have lowest frequency. The decrease of models height and the frequency pattern is lower. These outcomes prove bone defects to affect the structure of implant/alveolus and reduce the stability of implants. This investigate provides simultaneously follow up research methods for the experiment of irregular bony defects and actual size implant/alveolus models.en_US
