摘要 在临床种植修复后常出现固位螺丝松动的问题,为此学者们进行了大量的研究,认为螺丝预负荷、螺丝材质与形态、植体-基台界面间的密合度及其连接设计、咬合力大小是影响螺丝固位的重要因素。本文从以上几个方面,对螺丝固位的机械原理和引起松动原因的国内外相关研究进展进行综述。 The problem of retentive screw loosening often occurs after clinical restoration.There are many factors that affect the screw retention,such as the screw preload,screw material and morphology,the degree of cohesion between the implant-abutment interface and its connection design,and occlusion force.This article intends to discuss the mechanical principles and causes for the loosening of fixing screws and the latest relevant research progress.
