<p>There is a need for synthetic, restorable bone grafts with improved handling, which are flexible, compression resistant, bioactive or osteoactive, osteostimulative, osteoconductive and osteoinductive, and highly porous and have interconnected macro-, meso-, and microporosity for promoting capillary action of fluids, recruitment of cells for bone formation, and permitting angiogenesis. Further, there is a need for bone grafts with fluid wicking and retention properties capable of delivering cells and molecules to the body and which are bioactive flowable or moldable, shapeable graft materials that can occupy voids of varying shapes for restoring bone defects. The invention relates to biocomopatible bone grafts for repairing bone defects and a kit for the preparation of a bone graft comprising a bone graft material comprising a blend of resorbable collagen and resorbable calcium phosphate; and a separate container of bioactive glasses.</p> |
