Purpose
To evaluate the effect of cleft width and the pre-surgical position of the permanent cuspid, on the success of secondary alveolar bone grafts, using preoperative and post-operative radiographs.
Methodology
A total of 20 cases treated with secondary alveolar bone grafting for alveolar clefts were included in the study. Pre-surgical maxillary occlusal radiograph was used to determine the cleft width. Canine position was assessed by marking 6 points on a pre-surgical intra oral periapical radiograph. Alveolar bone contour and the success of bone grafts were determined using 11 points marked on post-operative periapical radiographs taken after a minimum follow-up of 6 months.
Results
Linear regression analysis of pre-operative cleft width and pre-operative position of the permanent cuspid were carried out on the bone graft success which was determined using post-surgical periapical radiographs. P < 0.05 was set. The results obtained had weak correlations and were statistically not significant.
Conclusion
We concluded that the success of the alveolar bone graft has minimal or no relation to the pre-operative width of the cleft or the position of the permanent cuspid at the time of grafting.
