Implant-supported prostheses consist of three components: the osseointegrated implant body, an abutment connected via an abutment screw and the prosthesis. One of the most common complications associated with implant-supported prostheses is the loosening and subsequent fracture of the implant abutment screw, often due to faulty prosthesis design, occlusal overload or biomechanical failures.
Materials and MethodsThis technical note presents a novel technique for retrieval of broken implant abutment screw using straight surgical handpiece, micromotor and a 701 surgical carbide flat fissure bur. The flat fissure surgical carbide bur is driven at very low speed (5000 RPM) in an anticlockwise direction, gently touching the outer surface the broken abutment screw to unthread it from the osseointegrated implant without damaging the implant internal hex design.
ResultsThe technique is safe, effective and economical for retrieving broken abutment screws from osseointegrated dental implants without compromising the integrity of the implant–abutment connection.
ConclusionThe technique’s feasibility and minimal complication rate makes it a valuable addition to implant dentistry, allowing for the preservation of existing implants and facilitating continued prosthetic rehabilitation.
