  • Artificial bone implants, or bone grafts, of polymeric composites with bone forming properties
    Patent number: 9913932
    Abstract: The present invention relates to methods for providing polymeric composites with bone forming, such as with osteogenic and/or osteoinductive and/or osteoconductive, properties. The present invention further relates to polymeric composites provided by the present method and the use of thereof for bone implants, or grafts, specifically the use thereof for orbital floor reconstruction. Specifically, the present invention relates to methods for providing a composite with bone forming properties, the method comprises the steps of: a) providing a liquid, or liquefied, polymeric composition of homopolymers or copolymers of 1,3-trimethylene carbonate (TMC); b) adding to said liquid, or liquefied, polymeric composition one or more agents with osteogenic and/or osteoinductive and/or osteoconductive properties thereby providing a dispersion of said agents in said liquid or liquefied polymeric composition; and c) crosslinking the product obtained, thereby providing a composite with bone forming properties.
