Dental implants are disclosed. Dental implants of the present invention, fixtures； Comprising an insertion portion inserted into the fastening groove of the fixture and a protrusion projecting to the upper portion of the fixture is provided with a through hole penetrating through the insertion portion and the protrusion is provided in the circumferential direction so that the protrusion can be extended to a predetermined or more by an external force Abutment is provided with a plurality of incision holes spaced apart from each other along； An artificial tooth coupled to the protrusion in such a manner as to surround the outside of the protrusion of the abutment； And a fixing screw inserted into the through hole and having one end coupled to the fixture to fix the abutment with respect to the fixture, wherein the protrusion of the abutment extends more than a predetermined time when the fixing screw is coupled to the fixture. , The artificial tooth is forcibly press-fitted to the extended protrusion is characterized in that the coupling. According to the present invention, the inclined surface provided on the inner surface of the abutment of the abutment, the inclined surface provided on the outer surface of the head of the fixing screw further extends the outer surface of the protrusion to the outside to increase the cross-sectional area, and similarly put the inclined surface on the inner surface of the insertion hole of the artificial tooth Coupling force between the artificial tooth and the abutment can be extended relatively more than the initial state of the abutment when the artificial tooth and the abutment are bonded to each other by making the outer surface and the inner surface of the insertion hole closely contact each other. It can be increased significantly compared to the conventional.치과용 임플란트가 개시된다. 본 발명의 치과용 임플란트는, 픽스쳐； 상기 픽스쳐의 체결홈에 삽입되는 삽입부와 상기 픽스쳐 상부로 돌출되는 돌출부로 구성되며 상기 삽입부와 돌출부를 관통하는 관통홀이 마련되되 상기 돌출부는 외력에 의해 일정 이상 외측으로 확장 가능하도록 그 원주 방향을 따라 서로 이격되게
