Abstract |
Introduction |
Mandibular incisor axis correction can be challenging in non-extraction orthodontic treatment planning. Mandibular anterior segmental subapical osteotomy (MASSO) is a surgical approach, which can be used to reposition incisor axis, improve occlusal function and enhance the soft tissue profile.
Methods |
Twenty-eight patients, mean age 22.6 years (16–39, SD=6.69), were treated for MASSO for correction of Class II dentoskeletal deformity, in addition to other orthognathic procedures. Retrospective analysis was performed on lateral cephalogram measurements, at the end of presurgical orthodontics and 6 months after completion of post-surgical orthodontics.
Results |
Mandibular incisor axis was corrected from a presurgical incisor to mandibular plane angle group mean of 109° (94–122, SD=7.97) to 95° (88–105, SD=3.79). Patients were followed for an average of 31 months after treatment completion, with no detected dentoskeletal complication or relapse.
Conclusion |
MASSO is an efficient and safe surgical procedure for incisor axis correction.
