Abstract

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. Futher, 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.

Description

technical field

[0001] The present invention relates to a composite implant having a porous structure filled with biodegradable alloy and a method for manufacturing the composite implant. More particularly, the present invention relates to a composite implant having a porous structure filled with biodegradable magnesium (magnesium) or magnesium-based alloy (magnesium-based alloy), thus having a Controllable biodegradation rate, which has high strength and excellent interfacial force between magnesium or magnesium-based alloy and bone tissue, and is also related to a method of manufacturing said composite implant . Background technique

[0002] Typical materials for medical therapeutic implants include metals, ceramics, polymers, and the like. Among them, metal implants have excellent mechanical properties and workability, but there are still problems such as stress shielding, image degradation, implant displacement, etc. migration) and so on. Furthermore, although cerami...
