种植支持式固定修复体两种固位方式的研究进展

Research progress on two ways of retention for implant-supported fixed prosthesis

种植支持式固定修复体的固位方式主要分为粘接固位与螺丝固位,学者们对于二者的选择一直存有争议,本文从这个问题出发,就其各自在种植修复体加工难易度及成本、修复体被动就位、取戴便利性、咬合负载应力、修复体固位力、美观效果、对周围组织健康的影响、种植体及修复体成功率八个方面,对最新研究进展做一综述,以期为临床应用提供参考。

There are two ways of retention for implant-supported fixed prosthesis, including cemented and screwed re- tained prosthesis. It＇s a controversial issue that which way is better among scholars. This article discusses the research progress on two ways of retention for implant-supported fixed restoration from eight aspects, including processing diffi- culty and cost of implant prosthesis, passive fit, retrievability, occlusal load, retention of prosthesis, esthetics, effects on the surrounding tissues, success rate of implant and prostheses, in order to provide a reference for clinical application
