Introduction: Autogenous bone grafting is often required in the reconstruction of extensive calvarial bone defects; however, it comes with limitations that may potentially cause patient morbidity. Recombinant human Bone Morphogenetic Protein-2 (rhBMP-2) has been widely developed for clinical use as a potent osteoblast inductors. The study aimed to prove using a chitosan scaffold combination to accelerate craniofacial bone regeneration, measured by increased osteocalcin expression, number of osteoblasts, formation of woven bone, and PDGF expression.

Method: The study used an experimental post-test-only control group design. Twenty-four male Wistar rats with calvarial bone defects were randomized into four treatment groups (control, rhBMP-2, chitosan scaffold, combination of rhBMP-2, and chitosan scaffold) and observed for four weeks. The resulting data was analyzed using an analytical Package for the Social Sciences (SPSS) software to test the hypothesis.

Result: The results showed the administration of chitosan scaffold, rhBMP-2, and a combination of rhBMP-2 and chitosan scaffold significantly increased osteocalcin expression, the number of osteoblasts, woven bone area formation, and PDGF expression compared to the control group (p<0.05). Significantly higher values (p<0.05) in all parameters were shown in the rhBMP-2 and chitosan scaffold combination group compared to those using chitosan scaffold or rhBMP-2 alone.

Conclusion: This study concluded that administering rhBMP-2 and chitosan scaffold combination accelerated the regeneration of calvarial bone defects in Wistar rats.
