Summary
Malaligned osseointegrated implants after facial trauma can be successfully corrected using segmental osteotomy. This procedure preserves implants and bone support, offering a viable solution for complex dental reconstructions.
Area of Science:
- Oral and Maxillofacial Surgery
- Dental Implantology
- Reconstructive Surgery
Background:
- Facial trauma can lead to significant tooth and alveolar bone loss, necessitating complex reconstructive procedures.
- Osseointegrated implants are crucial for restoring function and aesthetics, but malpositioning can occur.
- Bone grafting is often required to reconstruct alveolar defects before implant placement.
Observation:
- A healthy teenage girl experienced facial trauma resulting in tooth and alveolar bone loss.
- Brånemark implants were placed simultaneously with a bone graft for reconstruction.
- Initial implant positions and inclinations were deemed unfavorable for optimal prosthetic rehabilitation.
Findings:
- A segmental osteotomy procedure was performed to correct the malaligned osseointegrated implants.
- The segmental osteotomy successfully repositioned the implants without compromising their osseointegration or bone support.
- No implants were lost, and the surrounding bone remained stable throughout the correction process.
Implications:
- Segmental osteotomy is a viable technique for correcting malpositioned osseointegrated implants in complex cases.
- This approach can salvage implants and avoid the need for explantation and reoperation.
- It offers a predictable method for improving implant positioning, enhancing prosthetic outcomes in reconstructive dentistry.
