This clinical report describes the fractured hexagonal part of an implant abutment. The initial clinical sign was a loose abutment screw. Upon further clinical evaluation, the abutment was seen to have fractured and had wedged inside the implant body. Because the implant was a bone-level internal conical connection system, access and visibility were limited. A simple and economical technique with modified round-tip scissors was used to retrieve the fractured titanium abutment.
本临床报告描述了种植体基台六边形部分的骨折情况。最初的临床症状是基台螺丝松动。进一步临床评估发现，基台已发生骨折并楔入种植体内部。由于该种植体是骨水平内部锥形连接系统，操作通道和视野受限。采用一种使用改良圆头剪刀的简单且经济的技术取出了骨折的钛基台。
