| 摘要 |
The invention provides an artificial tooth root having acid resistance and anti-adherence of sordes and various germs, consisting of a substrate and a coating of calcium phosphate based ceramic having bioaffinity formed on the surface of this substrate, the substrate is composed of a polymer, ceramic, metal, or other material, the surface of the ceramic coating on the substrate surface is endowed with a protrusion-and-recession configuration, and is, chemically modified, and to a method for producing the artificial tooth root, by forming a coating of calcium phosphate based ceramic having bioaffinity over a substrate while imparting protrusions and recessions thereto, masking an area of the ceramic coating surface of which bioaffinity is required, and fixing a silane coupling agent exclusively over a predetermined area of the ceramic coating surface. |
