植體贋復物與植體周圍骨吸收之關聯：文獻回顧
The Relationship Between Implant Restoration and Peri-implant Bone Resorption: A Literature Review
摘要
牙科植體應用在全口或局部缺牙病患的重建已有多年歷史，臨床上已有相當高的長期成功率，但植體周圍骨吸收的發生也令臨床醫師困擾。目前文獻已經提出多種植體周圍骨吸收的風險因子，而植體贋復物與植體周圍骨吸收之關聯則是近幾年才開始被討論的議題。本文獻針對植體贋復物外型、贋復支柱體（abutment）或平滑領（smooth collar）高度與植體周圍骨吸收之關係進行回顧，結果顯示骨水平植體的贋復物輪廓角度（emergence angle） ≥ 30度、輪廓外型（emergence profile）為凸（convex）、贋復支柱體較短會有較高的植體周圍炎盛行率或骨頭吸收。然而這一部分的文章目前還偏少，未來還需要更多研究來驗證，但仍提供臨床醫師在治療計畫擬定及贋復物製作時做為參考。

Dental implants have been used as a treatment option for oral rehabilitation of fully or partially edentulous patients for many years; and the predictability and long-term success have been well documented. However, the occurrence of peri-implant bone resorption presents a challenge to clinicians. Although several risk factors for peri-implant bone resorption have been established, the relationship between peri-implant bone resorption and implant restoration design has only been discussed in recent years. This review article focuses on whether an implant restoration's contour, abutment height or smooth collar height is associated with peri-implant bone resorption. The results showed that a greater prevalence of bone resorption around an implant was observed when an implant restoration's emergence angle was ≥30 degree, emergence profile was convex, and abutment length was shorter in bone level implants. Although further studies are needed to verify these results, clinicians can be aware of such characteristics during treatment planning and prosthesis fabrication.
