Characterization of porous scaffold from chitosan-gelatin/hydroxyapatite for bone grafting
Bone tissue engineering is a new treatment technique for bone grafting. This procedure can regenerate damaged bone by implanting scaffolding to provide mechanical support in gap areas. The scaffold acts as a temporary matrix for cell proliferation until new bone tissue is completely regenerated. Thi...
