Summary
The intra-sinusal bone ring technique combined with Le Fort 1 osteotomy effectively corrects jaw discrepancies. This method ensures high primary retention and satisfactory osseointegration for dental implants in cases of tooth loss.
Area of Science:
- Oral and Maxillofacial Surgery
- Dental Implantology
- Orthognathic Surgery
Background:
- Le Fort 1 osteotomy is a common procedure for correcting midface hypoplasia and dental malocclusions.
- Rehabilitation of severe tooth loss often requires advanced bone augmentation techniques.
- Intra-sinusal bone grafting offers a solution for maxillary defects.
Observation:
- A 57-year-old male patient presented with severe tooth loss and skeletal malocclusion (Class III).
- Treatment involved Le Fort 1 osteotomy combined with the intra-sinusal bone ring technique for dental implant rehabilitation.
- The procedure was performed under general anesthesia.
Findings:
- High primary stability was achieved for both the dental implant and the bone graft.
- Radiographic evaluation confirmed successful graft healing and implant osseointegration.
- The combined technique demonstrated favorable outcomes in managing jaw discrepancy and facilitating implant placement.
Implications:
- The intra-sinusal bone ring technique is a viable option for correcting jaw discrepancies in conjunction with Le Fort 1 osteotomy.
- This approach is suitable for cases involving upper molar region tooth loss with adequate residual bone height (≥3mm).
- Successful osseointegration supports long-term dental implant stability and function.
