    if the upper rubbers have a greater tension than the lower the anterior teeth will be shortened; and the reverse will be the case when the lower rubbers exert the greater pressure. AVhen it is desirable to shorten the teeth very considerably it is better to band both centrals and laterals as, otherwise, the banded teeth will be shortened while the others will remain their original length. To remove the boAV or change the ])osition it is only necessary to detach the bow ends from the head cap and slip the vStandard from the chuck. The chuck is readily Fig. 13. sprung off the bar by a slight lateral movement. To connect the head cap with the protrusion bow, cut one end of each rubber to form straight pieces, and wnth a rubber-dam punch make a hole one-half inch from one end of each piece. Place these over the buttons of the cap, the shorter rubbers over the buttons nearest the lacing. Then place the protrusion bow on the chuck and punch boles in the other end of each of the rubbers at a point corresponding to the ends of the bow. Also punch three or four holes above these, three- eighths to one-half inch apart, and the tension exerted by these rubbers can be regulated by placing the curved hook of the protrusion bow through the proper holes in the rubber.
