Summary
Distraction osteogenesis effectively lengthens the alveolar process vertically, offering a reliable alternative to traditional reconstructive methods. This technique minimizes donor site morbidity and blood loss, enhancing soft tissue outcomes in maxillofacial surgery.
Area of Science:
- Maxillofacial Surgery
- Orthodontics
- Regenerative Medicine
Background:
- Distraction osteogenesis has become a vital tool in maxillofacial reconstruction since 1992.
- It offers advantages over conventional bone grafting, including reduced donor site morbidity and blood loss.
- Vertical lengthening of the alveolar process is now a clinically established application.
Observation:
- A 16-year-old patient with ankylosed incisors and underdeveloped alveolar process due to childhood trauma was treated.
- A custom tooth-borne distraction device was used for vertical alveolar distraction osteogenesis.
- The distraction device facilitated gradual bone lengthening, followed by fixation and a 6-week retention period.
Findings:
- The treatment successfully achieved vertical lengthening of the alveolar process.
- The patient exhibited stable results 1.5 years post-treatment, with good bone consolidation.
- A physiologically shaped gingivobuccal sulcus was restored.
Implications:
- Vertical alveolar distraction osteogenesis using tooth-borne devices is a viable option for specific cases.
- This technique avoids a second surgical procedure for bone grafting.
- It reduces the risk of dental root injury associated with fixation screws.
