Effect of pore size in bone regeneration using polydopamine-laced hydroxyapatite collagen calcium silicate scaffolds fabricated by 3D mould printing technology.

Based on our results, which demonstrated improved new bone formation in 500 μm pores scaffold, we can conclude that effective scaffold pore size that induces osteointegration and bone regeneration is around 500 μm for HCCS-PDA nanocomposite scaffold.
