Summary
This study introduces a novel surgical approach for correcting severe anterior protrusion in adults with thin alveolar bone. The technique offers an effective alternative to traditional orthognathic surgery, improving outcomes for complex cases.
Area of Science:
- Oral and Maxillofacial Surgery
- Orthodontics
- Skeletal Anchorage
Background:
- Severe anterior protrusion in adults with extremely thin alveolus presents a surgical challenge.
- Conventional orthognathic surgery may not be suitable for all patients.
- An alternative surgical treatment is needed to address this specific patient demographic.
Observation:
- A novel surgical technique involving wide linear corticotomy and a palatal bone-borne retractor was employed in the maxilla.
- Skeletal anchorage facilitated orthopedic force application for bony block movement.
- Anterior segmental osteotomy (ASO) and premolar extraction were performed in the mandible.
Findings:
- Maxillary bony block movement via corticotomy and bone-borne retractors was successful without complications.
- Biocreative orthodontics strategy (BOS) effectively closed residual extraction spaces.
- Mandibular anterior segmental retraction was efficiently achieved using ASO.
Implications:
- This combined surgical approach offers an effective alternative to orthognathic surgery for adults with protrusion and thin alveolus.
- Biocreative orthodontics strategy (BOS) provides a simple and effective method for anterior teeth retraction.
- The technique expands treatment options for complex dentofacial deformities.
