[Bone graft healing]. / La cicatrisation des greffes osseuses.

ABSTRACT

Bone graft healing involves an invasive process where vessels and cells penetrate the graft material to enable neoformation of bone. The origin of the material and its intrinsic properties and morphology are factors which affect its resorption and replacement. The first step involve formation of bone via the osteoconductive properties of the graft. For autologous bone, graft resorption enables secondarly release of preserved bone proteins, favoring a process of osteo-induction which contributes to remodelling and graft replacement by neoformed bone.
