Abstract

Implant restorations can fail biologically or mechanically. Biological factors include unsuccessful osseointegration or presence of peri-implantitis. Mechanical failures include crown fracture, framework fracture, screw loosening, and screw fracture. Fracture of the implant abutment can be a serious problem as the fragment remaining inside the implant may prevent the implant from functioning efficiently. The procedure used for removal of the fractured screw portion is described in this clinical report.

摘要

种植体修复可能会出现生物学或机械性失败。生物学因素包括骨结合不成功或存在种植体周围炎。机械性失败包括牙冠折断、支架折断、螺钉松动和螺钉折断。种植体基台折断可能是一个严重问题，因为留在种植体内的碎片可能会妨碍种植体有效发挥功能。本临床报告描述了用于去除折断螺钉部分的操作过程。
