Abstract

This case report discusses the approach and considerations involved in retrieving a fractured implant abutment screw. A 69-year-old male patient presented with a dislodged implant prosthesis caused by a fractured abutment screw. The fracture occurred at the most apical portion of the screw, specifically in the threaded region, making its retrieval particularly challenging. The screw was successfully removed using a commercially available retrieval kit. The effectiveness of the kit was attributed to a guide that allowed the retrieval instrument to align precisely with the long axis of the implant. Without such a guide, a risk of damaging the internal threads of the implant fixture exists, potentially leading to the need for implant removal. Therefore, using a retrieval kit with a guide or fabricating a custom-made guide is crucial for preventing implant damage and ensuring proper alignment during the procedure.
