The bioactivity of the zirconia surface is still not enough to the surrounding living tissue, although many surface modification have been reported. We developed a novel method of Ca-ion incorporation into zirconia for enhancement of its bioactivity. According to element analytical results, calcium ions could be well incorporated into the zirconia surface after the firing with calcium acetate. The flexural strength and hardness did not changed after the coating. It can be expected that the Ca-ion incorporation may enhance its bioactivity.
