10例种植体折裂病例的临床分析

doi:10.13591/j.cnki.kqyx.2024.01.011

摘要/Abstract

摘要：

随着口腔种植技术的不断提高,口腔种植修复已在临床上广泛应用,与此同时种植体失败的情况也逐渐增多。种植术后感染、骨结合不良以及机械并发症均可导致种植失败。虽然种植体折裂在临床中不多见,但引起种植体折裂的原因值得临床医生的重视。种植体折裂主要与种植体直径、种植体连接方式、修复体牙位及修复设计、种植体周围骨吸收等相关。本研究通过典型病例对种植体折裂的相关原因进行分析,为临床工作提供一定的指导。

Abstract:

With the continuous improvement of oral implant technology, oral implant restoration has been widely used in clinical practice. At the same time, cases of implant failure have also increased. Infection, bad osseointegration and mechanical complications after implantation may lead to implantation failure. Although implant fracture is rare in clinical practice, its causes deserve the attention of clinicians. Implant fracture is mainly related to the implant diameter, prosthetic implant design and bone resorption around the implant. In this study, the relevant causes of implant fracture were analyzed through typical cases to provide some guidance for clinical practice.
