Title:
CHROMIUM-MODIFIED IMPLANT AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2017/073591
Kind Code:
A1
Abstract:
The purpose of the present invention is to develop an implant that acts on a living body through an unconventional mechanism and can strongly bond to a living tissue.
Provided is an implant (1) to be embedded in a living body for a medical purpose, said implant (1) being characterized in that a base material (2) of the implant comprises a metal, a metal alloy, a metal oxide or a ceramic, and a surface (3) of the base material is modified with a chromium group (4) having a hydroxy group. The implant (1) according to the present invention can easily release chromium ion (8). The chromium ion (8) thus released acts on a living body and promotes tissue formation between the implant (1) and a living tissue (5) by, for example, promoting the crosslinking of collagen (9) secreted by a cell (7). As a result, the bond between the implant (1) and the living tissue (5) can be strengthened.
