    • The present invention provides a composite implant comprising pores of a porous structure filled with a biodegradable magnesium-based alloy. Further, the present invention provides a composite implant which filles pores of the porous structure prepared by a metal, a ceramic or a polymer with a biodegradable magnesium-based alloy. Mechanical properties of the composite implant of the present invention are improved because a magnesium-based alloy filled in its pores increases the strength of a porous structure comprised of a metal, a ceramic or a polymer. Further, it can be expected that the magnesium-based alloy filled in the porous structure is decomposed in a living body, thus increasing bone formation rate. Accordingly bone tissue can be rapidly formed because the composite implant of the present invention has high strength and excellent interfacial force between the composite implant and bone tissue, compared to conventional porous materials.
    • 本发明提供了一种复合植入物,其包含填充有可生物降解的镁基合金的多孔结构的孔。 此外,本发明提供一种复合植入物,其填充由具有可生物降解的镁基合金的金属,陶瓷或聚合物制备的多孔结构的孔。 本发明的复合植入物的机械性能得到改善,因为填充在其孔中的镁基合金增加了由金属,陶瓷或聚合物构成的多孔结构的强度。 此外,可以预期填充在多孔结构中的镁基合金在生物体中分解,从而增加骨形成速率。 因此,与常规多孔材料相比,本发明的复合植入物具有高复合植入物和骨组织之间的高强度和优异的界面力,因此能够快速形成骨组织。
