Abstract
(EN)
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.
(FR)
La présente invention concerne un implant ayant une structure multi-poreuse et son procédé de fabrication et, plus particulièrement, un implant ayant une structure multi-poreuse et son procédé de fabrication, une partie de croissance osseuse ayant différentes porosités selon des parties de celle-ci étant conçue sur une surface de contact osseux de l'implant, de sorte à favoriser une interposition osseuse autogène d'un patient y compris sans ciment osseux et à assurer ainsi une force de fixation entre l'implant et un os et de sorte à prévenir l'affaiblissement de la résistance mécanique due à un changement brusque de porosité au niveau d'une surface limite entre l'implant et la partie de croissance osseuse.

본 발명은 다중 다공성 구조를 가지는 임플란트 및 그 제작방법에 관한 것으로, 더욱 상세하게는, 임플란트의 골접촉면 상에 부분별로 상이한 공극률을 가지는 골성장부를 구성하여, 골 시멘트 없이도 환자의 자생적인 골내성장을 촉진함에 따라 임플란트와 골 간의 고정력을 확보하고, 임플란트와 골성장부의 경계면 상에 급격한 공극률 변화로 기계적 강도가 약해지는 문제를 방지하는 다중 다공성 구조를 가지는 임플란트 및 그 제작방법에 관한 것이다.
