(Problem) 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. (Means of Solution) The implant body 2 is fixed in a contact configuration to bone, and includes the base material 2a formed from zirconia, and a surface layer 2b formed on the surface of the base material 2a and having a lower hardness than the base material 2a. Therefore, in addition to having superior mechanical strength due to the zirconia base material 2a, the soft and flexible surface layer 2b functions as a buffer layer to mitigate the difference in the degree of hardness between the bone and the base material 2a, and therefore the soft surface further improves the bone adhesion characteristics.
