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
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
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.
