Upper and lower jaw parts have simple movement structures, the occlusal error of 5 upper and lower jaw models is minimized, and the upper and lower jaw models are accurately mounted on an occlusal plane. A conventional articulator is manufactured by emulating the shape of upper and lower jaw movement and has a folding structure in which the position of the reference axis of the articulator 10 correspondstothecondyle. Thearticulatorhasastructureexcept for the movement of a specific muscle, so that errors occur in upper and lower jaw movement. Even if the errors are reduced byusingvariousauxiliaryunits, thepost-process is essentially required. Occlusion is not accurately performed in the 15 conventional articulator, but the structure of the articulator is excessively complicated and a worker has difficult with the work. The disclosure employs a reference axis on a line extending from a central plane of the upper and lower jaw fixing members, such that the tangential line of the rotation movement is 20 perpendicular to the occlusal plane. The disclosure moves up or down more similarly to physiological movement when comparing with the conventional articulator to finely adjust the occlusal state by using an auxiliary unit, so that the error margin of the articulator is minimized, and the operating structure and 25 the use of the upper and lower jaw fixing members are simplified.1/14 20 20a 28 27 2-22 26 26b -2 13 21 -- 26a 23 1 12 25 10a 10 Fig. 1 28 20a 20 26 222 26b 25 23 ?4 24a 1 12 10 Fig. 2
