| dc.description.abstract | 本研究以非接觸式檢測技術進行術後牙科植體界面骨缺損評估，設計各類體外骨缺損模型，並改變模型周圍邊界條件，以聲能激振-位移響應方式測得結構共振頻率，再與有限元素分析和市售穩固度檢測儀測試結果作比較，探討共振頻率與骨缺損深度和方位之關係，建立術後骨整合評估與骨缺損方位檢測技術，並驗證其準確性與可行性，結果顯示此檢測方式可成功辨識出各類缺損型態及方位，較穩固度檢測儀精確。預期本研究成果將可用於人工牙根植入初期及骨整合期間頻率監測，期能提供客觀量化結果作為骨整合檢測依據，協助醫師評估與預測術後植體界面及骨缺損狀況，適時予以修復治療，降低病患植牙手術失敗之可能性。

| dc.description.abstract | The aim of this study is applied the noncontact detection technique to assess interfacial bone defects after the dental implantation. A series of in-vitro bone defect models were designed as well as made, and their surrounding boundary conditions were also changed. The structural resonance frequency (RF) was first measured by the acoustic excitation-displacement response procedure, and then this result was applied to compare with the outcome of the commercial implant stability instrument measurement and the finite element analysis (FEA). Therefore, the correlation between the RF difference and the bone defect orientation/location can be determined, and the postoperative assessment can also be established. This technique promises to assist the dentist in diagnosing and decreases the failure of the dental surgery.
