Summary
Corticotomy-assisted expansion (CAE) offers an effective solution for true unilateral posterior crossbite in adults. This novel technique successfully corrected asymmetry and improved function in treated patients.
Area of Science:
- Orthodontics
- Maxillofacial Surgery
Background:
- True unilateral posterior crossbite in adults presents significant treatment challenges.
- Conventional expansion methods often exhibit limitations in addressing this complex malocclusion.
Observation:
- This study introduces corticotomy-assisted expansion (CAE), a novel technique for treating adult unilateral posterior crossbite.
- Two adult patients with asymmetric maxillary constriction were treated using modified corticotomy techniques and fixed orthodontic appliances.
Findings:
- CAE facilitated effective asymmetrical expansion in both cases.
- The treatment successfully established functional occlusion.
Implications:
- Unilateral CAE demonstrates potential as an effective and reliable method for correcting true unilateral crossbite in adults.
- This approach may offer improved outcomes for patients with asymmetric maxillary constriction.
