Abstract: A dental liner and a manufacturing method therefor are disclosed. The dental liner is a dental liner for coupling feldspar porcelain and zirconia and includes: silicon dioxide; aluminum oxide; 1,4-butanediol for maintaining the moisture of the dental liner and preventing the generation of layers; and a zirconia powder for coupling the dental liner and zirconia by strengthening chemical bonding of the dental liner and zirconia.

Abstract: The present invention provides a method for preparing an implant including preparing a mixed etching composition including hydrogen peroxide and a water-soluble carbonate compound and oxidatively etching an implant made of titanium or a titanium alloy by immersing the same in the etching composition; a titanium or titanium alloy implant prepared by oxidative etching with a mixed etching composition including hydrogen peroxide and a water-soluble carbonate compound; and a composition for treating surface of an implant containing hydrogen peroxide and a water-soluble carbonate compound. Further, the present invention relates to a titanium or titanium alloy implant which is prepared by oxidative etching with a mixed etching composition including hydrogen peroxide and a basic solution and on which surface bumps having continuous or discontinuous line-shaped open channel structures in nanoscale are irregularly formed, and a preparation method thereof.
