|20110287070||BONE REPAIR MATERIAL AND METHOD FOR PRODUCING THE SAME - Bone repair materials are disclosed, from which ions are hardly eluted in living body and which are superior in apatite-forming ability and resistance to apatite peeling and have a scratch resistance high enough for practical use. The material comprises a substrate made of titanium or titanium alloys, and a surface layer, made substantially of titanium oxide, along the surface of the substrate. The substrate has on the surface thereof irregularities of from 1 nm to 10 μm in average in both width and depth. The layer has a zeta potential of +4.5 mV or more under an aqueous solution environment of pH 6 to 8, and a critical scratch resistance of 35 mN or more when vibration 100 μm in amplitude is added to a stylus with a spring constant of 200 g/mm on the surface layer and the stylus is moved at a rate of 10 mm/sec under a load increasing at a rate of 100 mN/min.||11-24-2011|
|20110082562||BONE REPAIR MATERIAL AND METHOD FOR PRODUCING THE SAME - A bone repair material being superior in apatite-forming ability and its stability in a storage and high in scratch resistance is disclosed. The material is produced by a method comprising the steps of: immersing a substrate made of titanium or a titanium alloy in a first aqueous solution that does not contain calcium ions but contains at least one cation selected from the group consisting of sodium ions and potassium ions and is alkaline; immersing the substrate in a second aqueous solution that does not contain phosphate ions but contains calcium ions; heating the substrate in a dry atmosphere; and treating the substrate with hot water of 60° C. or higher or with steam.||04-07-2011|

|20090051082||METHOD FOR PRODUCING ARTIFICIAL BONE - A method for producing an artificial bone precursor is disclosed. The method comprises: extracting a part corresponding to a cancellous bone and/or a cortical bone from digitalized three-dimensional image data of a living bone, followed by setting a center line on the part; drawing a beam or a wall having a uniform diameter or thickness along the center line to form artificial bone image data; and stacking a sintered layer by laser-sintering a powder of titanium and the like based on the artificial bone image data. The precursor is suitable for an artificial bone having excellent osteoconductivity and osteoinductivity.||02-26-2009|
