  • Patent number: 9265861
    Abstract: The invention relates to novel composite materials based on a collagen matrix mineralized 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 mineralized 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 analog, a collagen derivative or a mixture of said collagens.
    Type: Grant

  • Publication number: 20150104490
    Abstract: A growth-inhibited hydroxyapatite is contained in agglomerates of prestructured collagen templates, wherein the prestructured collagen templates are denatured or broken up so that fibrillogenesis of the prestructured collagen templates is inhibited. Epitactic hydroxyapatite crystallites with a crystallite size below a critical nucleus radius are formed on the prestructured collagen templates.

  • Patent number: 8916690
    Abstract: 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.
