Abstract

The present invention relates to an implant having a multi-porous structure and a method for manufacturing same and, more particularly, to an implant having a multi-porous structure and a method for manufacturing same, wherein a bone growth part having different porosities according to portions thereof is configured on a bone contact surface of the implant, so as to promote a patient's autogenic bone ingrowth even without a bone cement and thus secure a fixation force between the implant and a bone and so as to prevent weakening of the mechanical strength due to a sudden porosity change at a boundary surface between the implant and the bone growth part.
