Notes:
Due to the merits of zirconia ceramics such as high strength, toughness, and abrasionresistance, as well as chemical stability in vivo, yttria-stabilized tetragonal zirconia polycrystals(Y-TZP) are currently used in the femoral head of hip prostheses. However, this material has a limitedrange of use because it is a bioinert material that does not interact with bone tissue and thus does noteasily integrate directly with bone. Therefore, addition of a material surface that enables the in vivoformation of a bone-like apatite layer that exhibits bioactivity and facilitates interactions andintegration with bone tissue is desired. In addition, by developing a surface structure that enhancesmechanical bonding, this material can be expected to be used as an alternative aggregate under loadbearing conditions. In the present study, structural design of the material surface, addition ofbioactivity using reagents treatment, confirmation of formation of the apatite layer using immersion insimulated body fluid, mechanical assessment, and wettability testing were conducted with theobjective of controlling interactions between zirconia ceramics and the body
