The main purpose of the present study was to compare the revision rates of alveolar bone grafting in cleft lip and palate (CLP) patients with and without orthodontic preparation. The dental record of 101 patients with unilateral cleft lip and palate were examined. Details were recorded of general characteristic, the need for revision, intraoral condition prior to surgery, surgical procedure and the cause of revision. The revision rates were 11.9% and 20.6% in orthodontic preparation and non-orthodontic preparation groups, respectively. The Fisher’s exact test showed that there was no difference in the revision rate between both groups. Intraoral conditions prior to grafting and different surgical procedures did not affect the success of alveolar bone grafting.
