中文摘要 | 本篇系統性文獻回顧目的為比較不同的植體支臺齒連接之設計對於植體支臺齒的穩定度所造成之影響。透過PubMed、Medline(Ovid)、Cochrane Library、Web of Science、Google Scholar等電子資料庫作系統性搜尋。此外還有針對引用文獻做進一步手動搜尋。結果共有53篇文獻被篩選引用於本篇文獻回顧內。所有文獻皆為體外實驗。根據實驗方法以及觀察目標可以進一步分類為(1)密合度(2)疲勞測試之機械性質表現(3)抗彎曲及最大力量乘載(4)螺絲扭力變化(5)壓力分佈等五大類。其結論為:(1)錐形連接有較好之密合度。(2)錐形連接於承受疲勞測試後機械表現較好。(3)對於何種植體支臺齒連接可減少較多螺絲扭力喪失尚無定論。(4)外六角連接易使壓力集中於植體-支臺齒交接處,內六角連接把壓力傳導至植體根尖處,錐形連接把壓力較均勻的分布於植體內。 |
英文摘要 | The current review aimed to investigate the stability of implant abutment complex with different implant-abutment connection designs. Systematic review was conducted by online search of database PubMed, Medline (Ovid), Cochrane Library, Web of Science, and Google Scholar up to June 10, 2015. Besides, manual search was based on searching references in articles about related studies. There are 53 studies included in this review article. The included studies could be further categorized into 5 groups according to the test objectives (1) sealing ability, (2) fatigue loading test performance, (3) bending moment and maximum load resistance, (4) torque value of screw and preload, (5) stress and strain distribution over implant abutment interface. The conclusions are the following. First of all, internal cone connection seems to have superior sealing ability and minimal micro-gap because of the large surface area between implant fixture and abutment. Secondly, internal cone connection have better mechanical performance under fatigue loading and bending force. Thirdly, performance of torque values and preload in different connection design are still inconclusive. Fourthly, external hex connection tends to have stress concentration over coronal area whereas internal hex connection tends to spread force down to fixture tip. Internal cone connection showed more uniformly distributed stresses. |
