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.

L'invention porte sur un corps d'implant, sur son procédé de fabrication et sur un implant dentaire ; ledit corps d'implant ayant une bonne biocompatibilité et un haut degré de fixation à un os. Le corps d'implant (2) est stabilisé de façon à venir en contact avec l'os, ledit corps d'implant (2) comprenant un matériau de base (2a) formé de zirconium, et une couche de surface (2b) qui est plus molle que le matériau de base (2a) et qui est formée sur la surface du matériau de base (2a). Plus spécifiquement, le corps d'implant n'est pas uniquement supérieur en résistance mécanique du fait que le matériau de base (2a) est constitué de zirconium, mais également du fait que la couche de surface molle flexible (2b) agit en tant que couche tampon pour faciliter la différence du degré de dureté entre l'os et le matériau de base (2a). La surface molle améliore également l'adhésion du corps d'implant (2a) à l'os.
