A working model for a lower jaw is disposed on the bottom of an articulator, a pair of support rods are disposed on both sides of the articulator so as to extend upward from the bottom of the articulator, a pair of joint portions are provided on top of the paired supprt rods to support both end portions of a shaft, a working model for an upper jaw is mounted to that shaft to permit movement of the upper working model relative to the lower working model, a pair of side pins are disposed at upper, right and left, outside positions of artificial teeth mounted into the articulator, and a tooth aligning device is mounted to the side pins. Further, a center pin is mounted along the midline of the articulator, and holding portions for mouting the tooth aligning device are formed on the support rods and the center pin.
