Methods Three unilateral complete alveolar cleft patients were chosen in this study. Pa- tients were examined before and after alveolar bone grafting, after orthodontic treatment by dental CT. The alveolar bone shape changing after orthodontic teeth moving in bone graft area was evaluated. Results The orthodontic teeth could move in the bony graft area, and graft alveolar bone could reshape the morphology followed the teeth move in. Conclusion Alveolar bo
