Abstract：BACKGROUND: In alveolar cleft patients, the amount of bone stock after alveolar bone grafting is mostly measured and analyzed by two-dimensional imaging, which can result in a large error. OBJECTIVE: To evaluate the 6-month osteogenesis of alveolar bone graft in alveolar cleft patients using cone beam CT. METHODS:Alveolar bone grafting was performed in 25 patients with unilateral complete alveolar cleft. The patients were folowed up for 6 months after surgery and the osteogenesis of the bone graft was evaluated by CBCT. RESULTS AND CONCLUSION:After the surgery, the labial bone support was better than the palatal one. There were significant differences in the alveolar bone thickness of the cleft region and the normal region of the central incisor as wel as the alveolar bone thickness of the cleft region and the normal region of the canine tooth 0 mm distant to the alveolar crest. These findings indicate that the palatal bone support is less than the labial one, and the bone support of the central incisor is not satisfactory, which provide the basis for the tooth movement in the alveolar bone grafting and the orthodontics treatment.
