ABSTRACT:
A hard tissue repairing material includes zirconia as a base material. A surface of the base material has a hydrophilic group. The hydrophilic group is bonded to zirconium atom in the base material. The base material may contain at least an ionic component that is selected from a group consisting of calcium ion, sodium ion, potassium ion, and phosphate ions within the surface. A hard tissue repairing material may include zirconia as a base material and a layer of a main component of an apatite. The layer of the apatite may be formed on a hydrophilic group bonded to zirconium atom in the base material.
