The present invention relates to a round bar for abutment processing, and is directed to a round bar for a customer abutment that matches the shape of a gum of each user with a placement position.A rosette for abutment processing according to the present invention includes a body, a grip portion, and a coupling portion, and a coupling hole is formed. The body is cylindrical to be machined into abutment. The gripping portion is protruded on the upper portion of the body so as to be gripped by the bite for machining the body. The engaging portion is protruded to the lower portion of the body so as to be inserted into the fixture and mounted thereon. Wherein the fastening hole is formed in the fixing hole so as to penetrate from the gripping portion to the engaging portion so that a screw coupled to the fixture can be inserted and that one side of the outer circumferential surface is tapered so as to press the screw coupled to the fixture, Tapered.Further, in the round bar for abutment processing according to the present invention, it is preferable that the engaging portion is formed in a polygonal shape so as not to rotate in the fixture.According to the present invention, since the abutment round bar provided with the fastening hole is provided, it is not necessary to process the fastening hole in the abutment processing.In addition, the abutment fabricated according to the present invention has a tapered portion which is pressed in contact with the tapered surface of the tapered screw, thereby preventing the screw from being released from the fixture.본 발명은 어버트먼트 가공용 환봉에 대한 것으로서, 사용자 개개인의 잇몸형태와 식립위치를 맞춘 커스터머용 어버트먼트 가공용 환봉에 대한 것이다.본 발명에 따른 어버트먼트 가공용 환봉은 바디, 파지부 및 결합부를 포함하며, 체결홀이 형성된다. 상기 바디는 어버트먼트로 가공될 원통형이다. 상기 파지부는 상기 바디를 가공하기 위하여 바이트에 파지될 수 있도록 상기 바디의 상부에 돌기된다. 상기 결합부는 픽스쳐에 삽입되어 장착될 수 있도록 상기 바디의 하부에 돌기된다. 상기 체결홀은 상기 픽스쳐에 결합되는 스크류가 삽입될 수 있도록 상기 파지부에서 상기 결합부까지 관통되고, 외주면의 일측이 테이퍼져서 상기 픽스쳐에 결합된 상기 스크류를 가압할 수 있도록 상기 일측과 접촉하는 일측이 테이퍼진다.또한, 본 발명에 따른 어버트먼트 가공용 환봉에 있어서, 상기
