摘要：
The present invention relates to: a method for preparing an implant, comprising the steps of preparing a mixture etching composition containing hydrogen peroxide and a water-soluble carbonate compound, and oxidatively etching an implant, which is made from titanium or a titanium alloy, by immersing the same in the etching composition a titanium or titanium alloy implant prepared by being oxidatively etched with a mixture etching composition containing hydrogen peroxide and a water-soluble carbonate compound and a composition for surface-treating an implant, containing hydrogen peroxide and a water-soluble carbonate compound. In addition, the present invention relates to: a titanium or titanium alloy implant which is prepared by being oxidatively etched with an etching composition containing hydrogen peroxide and a basic solution and in which irregularities of an open channel structure having the shape of a continuous or discontinuous nanoscale line are formed on the surface thereof and a preparation method therefor. The surface of a titanium alloy treated by using the mixture etching composition containing hydrogen peroxide and a carbonate compound or the etching composition containing hydrogen peroxide and a basic solution of the present invention comprises micrometer-sized irregularities and channel-shaped nanometer-sized irregularities, and thus has an increased surface area, can have improved wettability and can effectively promote cell proliferation and osteocyte differentiation. In addition, the composition is environmentally friendly since no chemical compounds such as a strong acid are contained, and biocompatibility can be improved since such materials can be prevented from remaining on the surface, and thus the composition can be useful for implant surface treatment.La présente invention concerne : un procédé de préparation dun implant, comprenant les étapes consistant à préparer un mélange de composition de gravure contenant du peroxyde dhydrogène et un c
