PURPOSE: An implant unit having a hook pin coupling structure is provided to remove the need of implanting bone and to reduce operation charges. CONSTITUTION: An implant unit having a hook pin coupling structure comprises a fixture(110) combined with alveolar bone, and an abutment(120) which is shaft-connected to the upper end of the fixture. A hook pin expanded in the axial direction is formed in the lower part of the abutment. In the fixture, a pin coupling body is formed. In the hook pin, a cut groove partitioned radially around the center of the axis is formed.
