Background: Although, dental implants have been a predictable option to support several types of restorations, mechanical problems are not uncommon. Retaining and abutment screw loosenings/fractures are one of the most common technical problems. Aim: To present a step-by-step technique in order to remove a broken locater abutment screw fragment. Materials and methods: A 56-year-old, edentulous man with a fractured locator abutment screw in an implant was referred to our clinic from a private practice. His dentist placed a narrow platform locator abutment onto a regular platform implant and the fracture occurred. Attempts to remove the fractured fragment using a periodontal probe and a manual screw removal driver were unsuccessful. Results: This clinical report presents a situation in which a fractured locater abutment screw fragment was successfully removed using an implant repair kit. Conclusion: A fractured locater abutment screw fragment was successfully removed using an implant repair kit including drills, drill guides and tapping instruments. To avoid similar complications, it is recommended to use appropriate manufacturer specified torque values in conjunction with compatible restorative components. Clinical significance: Retaining and abutment screw loosenings/fractures are one of the most common mechanical problems associated with the implant components. This clinical report showed how to remove a broken screw fragment using proper armamentarium and technique, which might help clinicians eliminate similar problems.
