DETACHABLE DENTAL IMPLANT SYSTEM

A detachable dental implant system includes: an implant body including an implantation part that is implanted in an alveolar bone and an abutment part that is positioned on a top of the implantation part and provides an outer inclination surface having a truncated pillar shape and an internal space with an open top; and a crown medium that is disposed between the abutment part and a prosthesis and fixes the prosthesis to the abutment part by itself, wherein the crown medium includes an accommodation space providing a first close contact inclination surface that is in close surface contact with the outer inclination surface and being able to accommodate the abutment part, and a distance holder extending downward from a ceiling of the accommodation space and inserted in the internal space of the abutment part with an end thereof fixed to the abutment part, and surface contact between the outer inclination surface and the first close contact inclination surface and fixing between the abutment part and the distance holder generate resistance torque that interferes with rotation of the crown medium with respect to the abutment part.
