Summary
Mandibular anterior segmental subapical osteotomy (MASSO) effectively corrects mandibular incisor axis in orthodontic patients. This safe surgical procedure offers significant improvements without complications or relapse.
Area of Science:
- Orthodontics and Maxillofacial Surgery
- Dental and Craniofacial Mechanics
Background:
- Correcting mandibular incisor axis is complex in non-extraction orthodontics.
- Mandibular anterior segmental subapical osteotomy (MASSO) offers a surgical solution.
- MASSO can improve occlusal function and soft tissue profile.
Purpose of the Study:
- To evaluate the efficacy of MASSO for mandibular incisor axis correction.
- To assess the stability and safety of MASSO in orthognathic surgery.
Main Methods:
- Retrospective analysis of 28 patients undergoing MASSO for Class II deformity.
- Lateral cephalograms analyzed pre- and post-orthodontic treatment.
- Follow-up averaged 31 months post-treatment completion.
Main Results:
- Significant correction of mandibular incisor axis achieved (mean angle change from 109° to 95°).
- No dentoskeletal complications or relapse detected during follow-up.
- Mean patient age was 22.6 years.
Conclusions:
- MASSO is an efficient surgical technique for incisor axis correction.
- The procedure is safe and provides stable results.
