Abstract: The conventional treatment for alveolar cleft is cancellous iliac bone grafting. However it is difficult to transfer and suture mucosal flaps and reconstruct blood supply in patients with wide alveolar cleft, and the success rate of bone grafts is lower. Alveolar bone distraction osteogenesis can effectively close or narrow the wide alveolar cleft, which is beneficial to improve the effect of bone grafting. This article reported a case of alveolar bone distraction osteogenesis for the treatment of congenital bilateral severe alveolar cleft. The osteotomy line we placed in the mesial aspect of the cleft and micro-implants and posterior teeth were used as anchorage, and power chains were applied to pull the bone back, narrowing the alveolar cleft and ameliorating the maxillary protrusion at the same time.

Key words: Alveolar cleft, Distraction osteogenesis, Bone grafting
