    terial is bent in the form of a loop, its two ends seated in the transverse groove of the beaks, as shown in Fig. 16, and the band material thus tightly drawn about the tooth. In addition to gentle force for closing the handles, pressure Fig. 16. the screw firmly tightened by means of a key. The loop is then worked over the crown of the tooth to be banded, Fig. 17. Fig. 17, to the position previously in- dicated by a pencil mark on the enamel. The handles are now pressed upon and should also be exerted simultaneously by the beaks of the pliers on the band mate- rial in an apical direction. This assists in taking up the slack in the band ma- terial at its incisal margin, thus gaining closer adaptation of the band at this point and avoiding the unpleasing crimps in the incisal margin so often in evidence in badly fitting bands. To assist in the flow of the metal the burnisher should be used on the lahial margins of the band only while pressure is exerted on the handles of the pliers. The band material is now cut between the beaks of the pliers and the pliers removed. The band is now gently re- moved from the tooth and soldered in the usual way, and there is one point in connection with the latter operation which must be borne in mind. A band made in this manner is such a perfect fit that it must be soldered without in the least changing its form or size. For this reason it must be very lightly held by the band-soldering pliers while it is being soldered so that the two jaws of the unsoldered band will not be unduly pressed together, as this would diminish the size of the finished bai. .1 and it would not go to place on the tooth.
