The present invention provides an articulator for a dental technician, comprising an upper jaw coupling unit and a lower jaw coupling unit. The upper jaw coupling unit includes: an upper jaw frame coupled to an upper jaw teeth model； a pivot bar coupled to one end part of the upper jaw frame so that axial directions of the pivot bar and the upper frame are perpendicular to each other； pivot shafts extended from both ends of the pivot bar； and a convex portion formed along the central outer circumferential surface of the pivot bar to provide a spherical contact surface. The lower jaw coupling unit includes: a lower jaw frame coupled to a lower jaw teeth model； a first column and a second column standing at an end portion of the lower jaw frame； a central column standing between the first column and the second column； U shaped first and second hooking units formed at an upper end of the first column and the second column, respectively, and each having the pivot shafts seated thereon； a mounting unit formed at an upper end of the central column with a corresponding shape so that one side spherical contact surface of the convex portion can be mounted； a second arm formed by connectedly extending a U shaped lower part of the first hooking unit and the second hooking unit； and a push shaft coupled to the central area of the second arm to elastically push the other side spherical contact surface of the convex portion. The present invention adds a pivot contact point between the upper coupling unit and the lower jaw coupling unit to freely control left and right side motion and front side motion generated at joints of an upper jaw and a lower jaw.본 발명은 상악 치모형이 결합하는 상악프레임, 상기 상악프레임의 일단부에 축방향이 서로 수직이 되도록 결합하는 피봇대, 상기 피봇대의 양단부에서 연장되는 피봇 샤프트, 및 상기 피봇대의 중심 영역 외주면을 따라 형성되어 구형 접면을 제공하는 볼록부를 포함하는 상악결합부, 및 하악 치모형이 결합하는 하악프레임, 상기 하악 프레임의 단부에 입설되는 제1컬럼과 제2컬럼, 상기 제1컬럼과 상기 제2컬럼 사이에 입설되는 중심컬럼, 상기 제1컬럼과 상기 제2컬럼의 상단부에 각각 형성되어 상기 피봇샤프트가 각각 안착되는 ⊃자 형상의 제1걸림부와 제2걸림부, 상기 볼록부의 일측 구형 접면이 안착할 수 있
