Incorrect management of a broken abutment screw

Objective: The aim of the present article is to present the incorrect management of a fractured abutment screw by a classic surtex post. Methods: Implant abutment screw fracture is an uncommon though challenging complication. A fractured abutment screw should be removed without damaging the threads of the screw channel to reuse the prosthesis. Results: To retrieve the fractured part without severing the threads, various procedures have been proposed, such as to try to unscrew the fractured part using a strong, straight and pointed probe, or to prepare a small dent into the center of the fractured part using a small round diamond burr or a fissure burr in a counter clockwise motion. Various screw removal kits have been introduced to this aim, but with inconsistent results. Conclusion: The use of classic surtex posts is not recommended.
