Patent ID: 8859008

Claim:
A synthetic material comprising: an organic phase (I); and a mineral phase (II), wherein the organic phase (I) comprises striated collagen fibrils constituted of collagen I triple helices and in which the periodicity of the striations is 67 nm, said fibrils being organized over a large distance according to a 3D geometry associating aligned domains and cholesteric domains, and also isotropic domains where they are not organized; the mineral phase (II) comprises apatite crystals having a hexagonal crystalline structure, space group 6/m, said crystals comprising at least calcium ions and at least phosphate ions; the axis c of the apatite crystals of the mineral phase is coaligned with the longitudinal axis of the striated collagen fibrils of the organic phase; the collagen content in said material is at least 75 mg/cm 3 .
