PURPOSE: An implant fixture is provided to have a high durability and to achieve excellent osseointergration by high biocompatibility. CONSTITUTION: An implant fixture is made of ceramics including zirconia. The implant fixture includes a monoclinic percentage of less than 1 volume%, and a padding part(1a) equipped with the arithmetic average roughness(Ra) of 1-5 micron. The content of zirconia is 86 mass% or greater to the total mass of the implant fixture. The implant fixture further includes alumina and/or yttria.
