Alternative Method to Salvage an Internally Damaged Implant using Cast Post

다국어 초록 (Multilingual Abstract)

Screw loosening and consequent screw fracturing are the main causes of mechanical complications of implants. When an abutment screw is fractured, the screw has to be removed and replaced without damaging the implant fixture thread for the new abutment. However, if the internal threads of the implant are unexpectedly deformed, implant removal may be required. Here, we introduce an alternative technique for salvaging an internally damaged implant using the custom cast post as an implant abutment without removing the implant.
