Abstract

Abstract : Objectives: To investigate the osteogenic effect of allograft bone (BIO-GENE) and autologous iliac crest bone graft in the alveolar cleft repair. Materials and Methods: A total of 131 patients with congenital unilateral alveolar cleft who consulted in our hospital from January 2016 to May 2021 were selected and divided into 3 groups according to the different bone restoration materials used. Group A totaling 43 cases was the autologous bone group; group B totaling 41 cases was the BIO-GENE group; and group C totaling 47 cases was the BMP-2+BIO-GENE group. The preoperative and postoperative cone beam CT data of the same patient were imported into MIMICS 21.0 in DICOM format. The preoperative cleft volume and newly formed bone volume were calculated by 3-dimensional reconstruction to measure their osteogenic rate. Results: The differences in osteogenesis rates were not statistically significant in the group B compared with the group A, and in the group C compared with the group B ( P >0.05 for both). The differences in osteogenesis rates were statistically significant in the group C compared with the group A ( P =0.003). Conclusions: Comparative studies found the allograft bone with an ideal artificial material to repair alveolar clefts has become possible. Meanwhile, the addition of BMP-2 in the allograft bone significantly increased the osteogenic rate.
