The dental implant includes a movable ring (400) which is inserted into a fixture, is screw-coupled to the lower end of the fixing screw (300) and moves up and down by the rotation of the fixing screw, and an expansion ring (500) which is inserted into the fixture fixes the abutment by pressurizing the inner wall of the fixture. The fixing screw passes through the expansion ring. The abutment comprises a lower abutment which is inserted into the fixture and an upper abutment which is rotationally inserted into the top of the lower abutment. |
