Abstract
A method for producing an implant whose surface is roughened by the sandblast method using shot material containing fluoroapatite. Fluoroapatite, compared to hydroxyapatite, has poor biocompatibility, but is superior in hardness. It also has a property of being dissolved in acid. As a result, by the sandblast method using shot material containing fluoroapatite, the surface roughening is performed quite effectively, and shot materials remained on the surface can easily be removed by acid.
