    摘要: The invention relates to growth-inhibited hydroxyapatite for improving bone healing. It differs from the apatites employed to date in that it releases calcium ions and phosphate ions in physiological solutions, which, unlike traditional hydroxyapatites, it does not bind. It thereby promotes bone regeneration and bone growth. The growth-inhibited hydroxyapatite contains in agglomerates of prestructured collagen templates on which hydroxyapatite crystals with a crystallite growth of below its critical nucleus radius are formed epitactically. It is prepared by the steps a) mineralization of prestructured collagen templates in supersaturated Ca- and phosphate-ion-containing solutions, where the prestructured collagen templates are capable of diffusion and/or migration, so that HAP crystallites grow epitactically on the collagen templates and the collagen templates grown together with HAP crystallites agglomerate due to their capability of diffusion and/or migration, b) separating off the agglomerates.

    摘要: The invention relates to novel composite materials based on a collagen matrix mineralised with silicate and calcium phosphate phases, to a method for the production thereof and use thereof as an implant material which can be shaped in a plurality of ways, a biological coating or active substance carrier. The claimed composite material comprises a collagen matrix which is mineralised with silicate and a calcium phosphate phase, said collagen being a recombinate collagen, collagen from Eumetazoa, sponge collagen from a sponge of the Demospongia class (horn sponges) or Calcarea (calcareous sponges), a synthetic collage analogue, a collagen derivative or a mixture of said collagens.
