摘要：The invention relates to a material that can be used as a bone substitute and to a method for the preparation thereof. The material comprises an organic phase (I) comprising striated collagen fibrils constituted of collagen I triple helices, 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; and a mineral phase (II) comprising apatite crystals having a hexagonal crystalline structure, space group 6/m, comprising at least calcium ions and phosphate ions; the axis
