Summary
This study introduces a hybrid technique for maxillary advancement in severe skeletal class III malocclusion, combining distraction osteogenesis with rigid internal fixation. The novel method effectively advances the maxilla with no relapse, improving outcomes for patients.
Area of Science:
- Craniofacial surgery
- Orthognathic surgery
- Regenerative medicine
Background:
- Distraction osteogenesis enhances traditional craniofacial surgery but external devices have drawbacks.
- A hybrid technique combining maxillary distraction with rigid internal fixation is proposed to overcome these limitations.
Observation:
- The study involved five patients with severe skeletal class III malocclusion, undergoing a hybrid technique for maxillary advancement.
- The average age was 17 years, with a latency period of 1-5 days and distraction at 1 mm/day.
Findings:
- The hybrid technique achieved an average maxillary advancement of 11.6 mm (range: 10-13 mm).
- No relapse was observed at an average follow-up of 25 months (range: 5-40 months).
Implications:
- This hybrid technique offers a viable alternative for significant maxillary advancement, potentially unattainable with traditional methods.
- It reduces the need for prolonged external hardware and optimizes dental occlusion, improving patient outcomes in complex malocclusions.
