The present invention relates to a hybrid type dental implant structure having an advantage of two-mold type and integrated type dental implant structures. The dental implant structure according to the present invention includes a fixture fixed to an alveolar bone and an abutment coupled to the fixture and bonded thereon with an artificial tooth, and forms an artificial dental root. The fixture includes: a lower part partially or entirely formed at an outer surface thereof with a screw screw-coupled to the alveolar bone, and fixed to the alveolar bone; and an upper part coupled to the abutment. The upper and lower parts of the fixture have a shape extending along a rotation axis of the screw. At least one protrusion, protruding from the outer surface of the upper part of the fixture to the outside in the direction of a diameter of the fixture, is formed at an upper part of the fixture. An outer surface of the abutment is bonded thereto with the artificial tooth, and faces and contacts a gingiva. A through-hole is formed inside the abutment, in which the lower part of the fixture passes through the through-hole, and the through-hole is formed in a shape complementing a shape of the upper part of the fixture so that the upper part of the fixture is mounted in a contacting state. An insert groove which a protrusion of the fixture is inserted into and interlocked with is formed from the through-hole toward the outside of the abutment, such that a side surface and a bottom surface of the protrusion are contacted to a side surface and a bottom surface of the insert groove to be supported, respectively, thereby preventing the abutment from being separated from the fixture and rotating with respect to the fixture. |
