    摘要: A composition suitable for bone replacement is provided. The composition is a nanocomposite matrix, resembling both the structure and the properties of natural bone, including morphology, composition and mechanical characteristics. The nanocomposite is preferably porous and comprises: (1) micro or nano scale cellulose crystals or fibres; (2) hydroxyapatite nanoparticles; (3) Poly L-Lactide Acid or poly glycolic acid; and (4) a coupling agent, for example a surfactant, preferably an anionic surfactant such as sodium dodecyl sulfate. The composition is useful as an artificial bone replacement or bone graft, is preferably biomimetic, and can be suitable for use, for example, in trabecular bone substitution and osteoanagenesis applications. A method of fabrication of the nanocomposite is also provided.

    摘要: 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.
