[0021] The device is in the mandibular lateral movement measurement state. Based on the mandibular lateral movement measurement area pointing mark information 12 and the alignment with the lower front teeth midline in the normal occlusal state as the first initial scale value, the first scale area and the second scale area are configured to respectively record the right shift scale value when the lower front teeth midline is in the extreme right shift movement position and the left shift scale value when the lower front teeth midline is in the extreme left shift movement position, so as to obtain the lateral right shift value and the lateral left shift value of this mandibular lateral movement measurement.
