Abstract
A synthetic bone graft is described which is adapted to be received within a bone defect and which is structurally load-bearing. The bone graft comprises an entirely synthetic graft body corresponding in shape and size to the bone defect. The graft body is composed of a plurality of superimposed multilayered structures, each of the multilayered structures having a biopolymer layer joined to a biomineral layer to define an interface therebetween. The biomineral layer has a stiffness that is greater than that of the biopolymer layer, and the biopolymer layer has a toughness that is less than that of the biomineral layer.
