Summary
This study found that 91% of alveolar bone grafting procedures were successful in creating a bony bridge. Preoperative cleft width did not significantly correlate with the eventual success of the graft.
Area of Science:
- Craniofacial Surgery
- Orthodontics
- Oral and Maxillofacial Surgery
Background:
- Alveolar bone grafting is a critical procedure for cleft palate patients.
- Presurgical orthodontics is commonly employed to prepare the maxillary arch for grafting.
Purpose of the Study:
- To evaluate the success rate of alveolar bone grafting.
- To determine the correlation between preoperative cleft width and graft success.
Main Methods:
- Review of 56 cleft sites with pre- and post-operative assessments.
- Utilized study models and radiographs for measurements.
- Employed distortion correction techniques for accurate cleft width and alveolar contour assessment.
Main Results:
- Achieved a 91% success rate for bony bridge formation across the cleft.
- Iliac crest grafts were used in 95% of cases.
- No significant correlation was found between preoperative cleft width and graft success.
Conclusions:
- Alveolar bone grafting demonstrates a high success rate in achieving bony union.
- Presurgical orthodontic expansion is a standard preparatory step.
- Preoperative cleft width is not a predictor of graft outcome.
