Abstract: Objective: To summarize the osteogenic effect of monocortical mandibular bone combined with calcium phosphate cement (CPC) powder containing recombinant human bone morphogenetic protein-2 (rhBMP-2) in alveolar bone graft. Methods: Patients with alveolar cleft treated by the above methods from December 2020 to November 2021 were reviewed, and the bone resorption and complications were analyzed. Results: A total of 8 cases were included, the average bone resorption rate was 28.88%. One case had wound dehiscence, and the curative effect was still good after treatment. One case suffered from wound dehiscence and infection 2 weeks after operation. The CT scan at 6 months after operation indicated that the graft bone was not continuous with the surrounding bone. At 8 months after operation, the bone block was discharged from the dehiscence. Conclusions: The effect of monocortical mandibular bone combined with CPC powder containing rhBMP-2 in repairing alveolar cleft was acceptable with lower bone absorption rate, higher new bone density, less trauma, and thus valuable clinical application.
