AbstractA grafting material comprising milled bone which has an initial coating of guanidine-extracted bone proteins which are dialyzed from solution. Unbound bone proteins are removed and this augmented milled bone is lyophized. A subsequent coat of anti-coagulated plasma containing plasma proteins is applied to the augmented milled bone. The unbound plasma proteins are removed from the coating by rinsing.
