ORTHODONTIC MEASURING GAUGE - This orthodontic measuring gauge was used to take facial measurements and was made by Dentomac. The metal segments were pushed into shape by the contours of the face and then traced onto paper to demonstrate to the patient the need for treatment. The knobs at either end of the segments were screwed into place to lock them into position. The device was attached to an adjustable wall-mounted bracket.
