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.
Claims11
A hard tissue repairing material, comprising:
- zirconia as a base material, wherein the zirconia has hydrophilic groups each bonded to one of the zirconium atoms at the surface of the of the zirconia;
- and
- a layer containing an apatite layer as a main component, which is formed on the hydrophilic groups.
A process for producing a hard tissue repairing material including a base material made of zirconia, the process comprising the steps of:
- preparing the base material made of zirconia including a plurality of zirconium atoms, wherein the zirconium atom is constituting the surface of the base material;
- and
- soaking the base material in an alkaline aqueous solution or an acid aqueous solution to bond a hydrophilic group to one of the zirconium atoms constituting the surface of the base material.
