Abstract:
1. A bone graft biomaterial comprised of a scaffold consisting of a biocompatible polymer and a bioceramic composite in a ratio of about 1:2 to about 2:1 wherein the bioceramic particles are less than 1.0 μm in diameter and wherein the scaffolds contain interconnected pores made via a gas foaming or a particulate leaching process, wherein the bioceramic particles are exposed on the surface of the biomaterial and wherein the biomaterial is impregnated with collagen after the pores are formed by forcing the collagen into the pores by placing the scaffold into a collagen solution and the solution is placed under a vacuum until the temperature is just above the freezing point of the collagen solution, the solution allowed to warm before being subjected to repeated cycles of vacuum and warming.
