植牙之機械性併發症:植體螺絲斷裂之處理-病例報告

Mechanical Complication Related to a Dental Implant: Management of an Implant Screw Fracture-Case Reports

摘要


植牙螺絲斷裂常造成臨床上的困擾,學者們提出各式取出斷裂螺絲的方法,但仍有些斷片無法被移出,而必須採取其他治療方式來解決此困境。本病例報告探討如何預防螺絲斷裂及取出斷片。病例一有二支植牙螺絲斷裂,兩螺絲都成功取出改以新的螺絲重建完成,而第二例以同一方式嘗試處理但卻失敗,最後手術將整支人工植體取出。

The fracture of an implant abutment screw can be a serious problem. Failing to remove the fractured screw fragment still occurs even after many different procedures that can be used for the removal of fractured screw fragments have been reported in the literature. This report presents one case where two fractured implant abutment screws were successfully removed as well as the other case where the same technique failed resulting in the removal of the implant fixture instead.
