Canine eruption into grafted bone in maxillary alveolar cleft defects
The Cleft Palate Journal
|January 1, 1982
Summary
Alveolar bone grafting in cleft patients facilitates canine eruption, though most cases require surgical uncovering and orthodontic intervention. Optimal timing for grafting improves canine eruption prognosis.
Area of Science:
- Craniofacial Surgery
- Orthodontics
- Pediatric Dentistry
Background:
- Alveolar bone grafting (secondary osteoplasty) is a common procedure for patients with alveolar clefts.
- Canine eruption through grafted alveolar sites presents unique challenges in orthodontics and surgery.
Purpose of the Study:
- To evaluate the eruption status and outcomes of canine teeth in patients who underwent secondary alveolar osteoplasty.
- To determine factors influencing successful canine eruption through grafted alveolar cleft sites.
Main Methods:
- Retrospective study of 46 patients with alveolar clefts (7-14 years old) who received alveolar bone grafts.
- Analysis of 64 affected canines using follow-up orthopantomographs to assess root development and eruption.
- Observation period ranged from 2-8 years post-surgery.
Main Results:
- All studied canines successfully erupted through the grafted bone.
- Spontaneous eruption occurred in 27% of cases; 17% required surgical uncovering, and 56% needed surgical uncovering with orthodontic assistance.
- All patients required orthodontic treatment for arch alignment post-grafting.
Conclusions:
- Canine eruption through alveolar bone grafts is achievable but frequently requires intervention.
- Favorable prognosis for canine eruption is associated with grafting at 1/4-1/2 canine root formation and patient age of 9-12 years.
- Close collaboration between orthodontists and surgeons is crucial for optimal outcomes in post-grafting management.
