FIXTURE FOR A DENTAL IMPLANT

摘要

A fixture for a dental implant is disclosed. The fixture for a dental implant according to the present invention comprises: a first body which is implanted in the lower region of a drill hole perforated in the alveolar bone of an oral cavity, such that the virtual line connecting the male threads formed on the outer surface of the first body is substantially parallel to the axial line of the drill hole; and a second body which has a diameter larger than the diameter of the cross-section of the first body, and which has an outer surface on which male threads are formed into a screw line substantially identical to that of the male threads of the first body, and which extends from the top of the first body and implanted into the upper region of the drill hole. The fixture of the present invention is prevented from moving when initially implanted into the drill hole drilled in the alveolar bone, to thus maintain the fixture implanting direction parallel to the axial line of the drill hole, thereby preventing implant failure in advance. Further, the fixture of the present invention is provided with maximum fixing force when implanted, and is thus prevented from moving, which might otherwise occur after implanting, ensuring the stability of dental implants.
