The features which Dr. Hollingsworth claims for his methodsare illustrated in the following directions: After making a band to fit the root in the ordinary way, place itin the mouth (see Fig. 577), and cut off on a line where the adjoin-ing teeth begin to turn to form the cusp (see c, Fig. 577). Place asmall piece of wax inside the band to assist in holding the cuspbutton, which should be selected to fit the circumference of theband, to articulate properly, and to correspond in shape with theother teeth (see b, Fig. 577). Remove the button, and place it on39 Fig. 580.
