Summary
A fractured implant abutment, initially presenting as a loose screw, was successfully retrieved. A novel technique using modified scissors provided an economical solution for this challenging dental implant complication.
Area of Science:
- Dental Implantology
- Biomaterials Science
Background:
- Implant abutment fractures can compromise dental restoration stability.
- Internal conical connection systems present unique challenges for retrieval of fractured components due to limited access.
Purpose of the Study:
- To describe a clinical case of a fractured implant abutment.
- To present a simple, economical retrieval technique for a fractured titanium abutment in a bone-level internal conical connection implant.
Main Methods:
- Clinical evaluation of a loose abutment screw.
- Identification of a fractured hexagonal abutment wedged within the implant body.
- Utilization of modified round-tip scissors for fractured abutment retrieval.
Main Results:
- The fractured titanium abutment was successfully retrieved using the modified scissor technique.
- The technique proved to be simple and economical, overcoming limited access in the internal conical connection implant.
Conclusions:
- Fractured implant abutments are a complication that can be managed effectively.
- Modified instruments can offer practical solutions for retrieving fractured components in challenging implant scenarios.
