Title:
POROUS SURFACE FOR IMPROVING THE BONE-FUSING ABILITY OF AN IMPLANT HAVING A MACRO/MICRO/NANO-SCALE THREE-PART STRUCTURE, AND PRODUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2013/109078
Kind Code:
A1
Abstract:
Disclosed are a titanium-based implant for biological transplantation having appropriate surface roughness and a hydrophilic surface over a wide surface area. The implant surface has a three-part structure on the nano scale, the micro scale and the macro scale. In the nano-scale structure, nanoparticles of titanium oxide form a hydrophilic surface, and these nanoparticles constitute the inner surfaces of micropores of a number of micrometers formed in uneven areas on the implant surface. The micro-scale uneven parts constitute an undulating surface having a surface roughness at the level of between 0.5 and 5 μm on the macro scale, and form a plurality of sunken areas of a number of tens to a number of hundreds of micrometers. The implant can be produced by moulding titanium metal or a titanium-based alloy into the desired shape, forming the micropores by blasting inorganic particles onto the surface by means of a method such as sandblasting and then carrying out acid processing of same, and by next producing titanium oxide nanoparticles by anodic oxidation before then carrying out a heat treatment as required.
