Background: Bone grafting of the cleft maxilla before eruption of the permanent cuspid has become an accepted part of the management of patients with clefts involving the maxillary alveolus. The reasons for performing a bone graft are to stabilize the maxillary segments and provide bony support for the teeth adjacent to the cleft. Objective: The aim of the present study is clinical and radiographic evaluation of the outcome and efficacy of sticky bone (mixture of autologous fibrin glue (AFG) and bovine bone graft) as a bone substitute for the treatment of alveolar cleft. Patients and Methods: 41 patients with a total of 58 alveolar clefts, 17 bilateral and 24 unilateral clefts, treated by alveolar bone grafts using sticky bone. Their age ranged from 6 to 18 years with a mean of 11.6. The follow-up was up to one year. Results: From a total number of 58 alveolar clefts. Adequate healing was resented in 47 of them [30 of them were class I (51.7%) and 17 were class II (17%)]. Inadequate bone healing occurred in 11 clefts [6 of them were class III (10.3%) and 5 were class IV (8.6%)]. Conclusions: Bone grafting of alveolar clefts is a mandatory step in the management of cleft lip and palate patients, sticky bone could be considered as promising and effective bony substitute and could be used efficiently for the treatment of cleft alveolus as an alternative to autogenous bone grafts to avoid harvesting bone of the patient and its complications and the earlier the grafting producers are done, the better quality of grafted bone.
