Summary
This study evaluated mandibular sagittal split osteotomy (MSSO) for anterior open bite correction. Results showed MSSO is a viable option, but long-term stability requires further investigation.
Area of Science:
- Dentistry
- Orthognathic Surgery
- Oral and Maxillofacial Surgery
Background:
- Anterior open bite presents significant functional and aesthetic challenges.
- Treatment of skeletal anterior open bite remains complex with debated approaches and high relapse rates.
- Osteotomy type is a key factor influencing relapse after orthognathic surgery.
Purpose of the Study:
- To assess the efficacy and stability of mandibular sagittal split osteotomy (MSSO) in correcting anterior open bite.
- To evaluate immediate postoperative and 1-year outcomes following MSSO for anterior open bite.
Main Methods:
- Retrospective evaluation of patients undergoing MSSO for anterior open bite correction.
- Analysis of cephalometric changes immediately after surgery and at 1-year follow-up.
Main Results:
- Mandibular sagittal split osteotomy (MSSO) demonstrated immediate correction of anterior open bite.
- Further analysis is needed to determine the long-term stability and relapse rates associated with MSSO in this context.
Conclusions:
- Mandibular sagittal split osteotomy (MSSO) can effectively correct anterior open bite.
- Long-term stability and potential for relapse following MSSO warrant continued investigation in orthognathic surgery.
