Abstract

A microlocking implant prosthetic system has recently been developed to address the limitations of conventional screw- and cement-retained implant-supported fixed dental prostheses. This prosthesis system consists of a precision-machined abutment and an attachment that includes zirconia balls and a nickel-titanium spring, thus providing retrievability and constant retention of the prosthesis. In addition, screw-related complications are avoided because there is no retention screw. The occlusal access hole is of a smaller diameter than that of conventional screw-retained prostheses, which is beneficial for esthetics and occlusion. It also prevents common complications of cement-retained prostheses because residual cement around the prosthesis can be removed extraorally. This article presents a clinical treatment with this new prosthetic system.

摘要

一种微锁植入物修复系统最近被开发出来，以解决传统螺丝和水泥固位的种植体支持固定义齿的局限性。该修复系统由精密加工的基台和一个附件组成，该附件包括氧化锆球和镍钛弹簧，从而提供了修复体的可摘性和持续的固位力。此外，由于没有固位螺丝，因此避免了与螺丝相关的并发症。与传统的螺丝固位修复体相比，该修复体的牙合面接入孔的直径更小，这有利于美观和咬合。它还可以防止水泥固位修复体的常见并发症，因为可以将修复体周围的残余水泥从口腔外清除。本文介绍了使用这种新的修复系统进行的临床治疗。
