Stage: PROBLEM TO BE SOLVED: To provide a zirconia prosthesis capable of easily applying an adhesion system including a combination of a pretreatment agent containing a silane coupling agent and a dental adhesion such as dental resin cement without a need to make a sandblast treatment essential to bond it to a target such as a tooth well, and usable for a long time in an environment in an oral cavity which becomes high in temperature and humidity.SOLUTION: The zirconia prosthesis in which only a surface layer part of an adhesive surface is selectively conjugated with a silicon dioxide is obtained by impregnating a front surface of a surface which becomes an adhesive surface after cutting a zirconia dental mill blank having a cut part made of, for example, a partially stabilized zirconia slightly porous calcined body by using a CAD/CAM system with a treatment liquid containing an aqueous solution or a suspension of alkali metal silicate such as sodium silicate to sinter it.SELECTED DRAWING: None (Grant)
