  • Bone repair material and method for producing the same
    Patent number: 9034051
    Abstract: 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.
    Type: Grant
    Filed: May 23, 2013
    Date of Patent: May 19, 2015
