Fabrication of Porous β-Tricalcium Phosphate with Collagen Composite Materials

Biomaterials have been developed and used for bone grafting. Here, we study a fabrication of composite for bone tissue engineering by combining tricalcium phosphate and collagen. This tricalcium phosphate and collagen composite material may be applicable for use as a bone substitute. The β-tricalcium phosphate (β-TCP) is the one of the most investigated biomaterials due to its biocompatibility and good bioactivity. The β-TCP is used in a filling purpose to the bone defect region such as bone fractures. It is known that β-TCP substitutes it for a self bone in the body. The ingredient of the real bone is made of hydroxyapatite and collagen. In this study, the purpose was at giving the mechanical property and biological property which were near to a bone with β-TCP and collagen this time. We evaluate what kind of action collagen addition.
