[Evaluation of the effect of bone nail and artificial periosteum combined with iliac cancellous bone grafting in repairing cleft lip and palate with alveolar cleft during dental replacement].

Purpose: To evaluate the effect of bone nail and artificial periosteum combined with iliac cancellous bone grafting in repairing cleft lip and palate with alveolar cleft during dental replacement.

Methods: The clinical data of 82 children with cleft lip and palate with alveolar cleft during dental replacement period were retrospectively analyzed from January 2020 to December 2023, and were divided into control group (iliac cancellous bone grafting alone, n=42) and experimental group (combined iliac cancellous bone grafting with bone nail and artificial periosteum, n=40) according to the operation method. The viable bone volume in bone graft area, absorption rate of whole bone graft and different bone graft areas, success rate of bone graft, survival rate of bone graft and complications were compared between the two groups.
