Abstract
To obtain improved bio-affinity and high bone attachment in an implant body, a method of manufacture for the implant body, and a dental implant. The implant body is fixed in a contact configuration to bone, and includes the base material formed from zirconia, and a surface layer formed on the surface of the base material and having a lower hardness than the base material. Therefore, in addition to having superior mechanical strength due to the zirconia base material, the soft and flexible surface layer functions as a buffer layer to mitigate the difference in the degree of hardness between the bone and the base material, and therefore the soft surface further improves the bone adhesion characteristics.

A method of manufacturing an implant body adapted to be fixed in a contact configuration to a bone, comprising:
- forming a zirconium hydroxide surface layer on a zirconia base material by irradiation of laser light, the surface layer formed by a reaction of the zirconia of the base material and moisture, wherein the surface layer has a lower hardness than the zirconia base material.
A method of manufacturing an implant body, comprising:
- providing a base material formed from zirconia;
- irradiating the base material in the presence of water vapor with a laser light;
- and
- forming a zirconium hydroxide surface layer on the zirconia base material, wherein the surface layer has a lower hardness than the zirconia base material.
