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.
