Evaluation of bone formation and residual graft maintenance in calvarial augmentation model. (A) Representative microcomputed tomography images of calvarial bone-graft sites at 3 and 5 weeks after surgery in the DBBM-Cb and DBBM-NCp groups. Yellow dotted lines indicate the boundaries of the guide tube, and red dotted lines represent the boundary between newly formed bone and residual graft material. (B) Bone volume fraction (BV/TV, %) of the augmented regions at 3 and 5 weeks. The DBBM-Cb group demonstrates significantly higher BV/TV than DBBM-NCp at 3 weeks (P < 0.05). (C) Vertical change in residual graft (RG) height (%) at 3 and 5 weeks. The DBBM-Cb group shows significantly less vertical reduction compared to DBBM-NCp at both time points (P < 0.05). BV bone volume, TV total volume of bone tissue, DBBM-NCp deproteinized bovine bone mineral with non-crosslinked porcine collagen (Bio-Oss Collagen, Geistlich Pharma, Switzerland), DBBM-Cb deproteinized bovine bone mineral with crosslinked bovine collagen (A-Oss Collagen, Osstem, Republic of Korea).
