Summary
Patient age and cleft type significantly influence secondary alveolar bone grafting (SABG) success in cleft lip and palate patients. Younger patients (10-12 years) and those with unilateral clefts show better outcomes.
Area of Science:
- Oral and Maxillofacial Surgery
- Pediatric Dentistry
- Craniofacial Anomalies
Background:
- Secondary alveolar bone grafting (SABG) is crucial for repairing alveolar defects in cleft lip and palate patients.
- Current assessment methods like 2D radiography are practical but may not fully capture factors influencing graft success, sometimes requiring revision surgeries.
Purpose of the Study:
- To identify clinical variables affecting SABG outcomes in cleft patients using 2D radiographic analysis.
- To enhance the understanding of factors predicting successful bone grafting in this population.
Main Methods:
- Retrospective analysis of 63 patients who underwent SABG between 2013-2023.
- Evaluation of variables including age, cleft type/size, surgical techniques, graft materials, and orthodontic timing.
- Assessment of graft efficacy using the Chelsea scale for bone bridging and ImageJ for bone density on conventional and digital 2D radiographs.
Main Results:
- Patient age and cleft type were significant predictors of SABG success (ORs 10.46 and 5.19, respectively).
- In conventional radiography, post-surgical orthodontic timing was key; in digital radiography, cleft type was the primary factor.
- Patients aged 10-12 years and those with unilateral clefts demonstrated higher success rates.
Conclusions:
- Patient age and cleft type are significant determinants of SABG success.
- Optimizing surgical timing and considering cleft characteristics can improve graft outcomes in cleft lip and palate patients.
