摘要:	『研究目的』本研究主要目的是探討人工牙根外接合、內接合和莫氏錐狀接合三種植體-支台齒不同接合型態的植體，在假牙裝置前、後分析比較臨床上植體周圍骨質流失與植體-支台齒接合型態之間的關係。『材料和方法』第一階段先收集中國醫藥大學附設醫院牙科部2002年~2010年間既有的根尖X光片資料，並將影像資料數位化及標準化之後做歸類處理。第二階段使用影像處理分析軟體Image J，量測手術後植體裝置假牙前、後，亦即受力前、受力後骨?流失的情形。本篇研究使用的植體，分為1.外六角、2.內八角與3.莫氏錐狀接合系統，此三種植體系統都種植在bone level。以三個手術時期(time phase)，區分為手術後4個月左右(Biological phase)、植體承受咬合力後3個月(Loading phase I)與6個月(Loading phase II)，比較三種不同接合形態的植體周圍骨流失的情形。本研究統計分析使用廣義估計方程式(GEE)做資料的建置並通過中國醫藥大學附設醫院人體試驗委員會審查。『結果』三種不同接合型態的植體於Biological phase、Loading phase I與的Loading phase II ，其骨質流失量沒有統計上顯著差異。不同time phase之間的骨質流失量，具有統計上顯著差異，且三種不同接合型態人工牙根於Biological phase的bone loss數值都比 Loading phase I 、 II的 bone loss高。此外下顎分析，Loading phase II和Biological phase沒有統計上顯著差異。『結論』基於既有的研究限制下，所得之結論為外接合、內接合及莫氏錐狀接合三種植體-支台齒接合型態，對於植體周圍骨的影響並沒有差異。 Purpose: The primary objective of this study was to investigate the impact of external, internal, and Morse taper implant-abutment connections on peri-implant bone levels prior to and after implant placement, by conducting a clinical analysis and comparison. Materials and Methods: In the first phase of this study, we collected, digitized, standardized, and classified the periapical x-ray data that was archived by the China Medical University Hospital Dental Department during the period of 2002 to 2010. In the second phase, we used Image J, a bio-image processing and analysis software to measure the bone loss prior to and after the loading of dental implant. Implants used in this study including external hex, Internal octagon and Morse taper implant-abutment connections. Three types of implant systems were placed at the bone level. Observation of the bone loss during time phases containing the periods of biological phase( 4 months after surgery) and the periods of Loading phase I ( 3 months after loading ) and loading phase II ( 6 months after loading. This study using the GEE (the generalized estimating equation) method to obtain the analysis data. Additionally, the protocol was reviewed and approved by the Institutional Review Board of China Medical University Hospital. Results: The comparisons of the bone loss of three types of implant-abutment connections show no statistical significance among the biological phase, Loading phase I, and Loading phase II. For the bone loss in each time phase, the values of ΔVBD (bone loss) obtained during the biological phase are greater than those obtained while Loading phases I and II for all three types of implant-abutment connections. In the lower arch analysis between biological phase and Loading phase II, the analysis results also show that no statistical significance. The analysis results show that statistical significance exists in every time phase pair. Conclusions: Within limitations of this study, the following conclusions can be drawn, the implant-abutment connection design appears to have no significant impact on peri-implant bone levels.
