The aim of this study was to clarify the factors which influenced the successful of bony bridging following bone grafts into the alveolar cleft with autogenous particulate cancellous bone harvested from iliac bone.<BR>The bone bridge build up in the alveolar cleft was assessed by periapical radiographs taken before and 18-23 months after the operation. Successful bony bridging defined as a bone bridge with a vertical height of greater than about 11mm, was observed in 123 of all 202 clefts. The frequency of successful bony bridging decreased with increasing severity of cleft type. Successful bony bridging was achieved in 81.8% of unilateral cleft lip and alveolus patients and in only 45.2% of bilateral cleft lip and palate patients. Moreover, the frequency of successful bony bridging was significantly negatively correlated with the width of the cleft. The present study has clearly shown at least two major determinants of successful bony bridging: 1) the cleft type, and 2) the width of the cleft.
