Then an impression in Teagues compound is taken ofeach separately, the bands removed, placed in impression, whichis then dried and filled with Mellotes or Babbitts metal. Thisgives you a die or metal tooth with band in place, with which anocclusal cap of 28 g. plate is swaged, band removed and soldered,which when finished and gold plated, all made in short order, hasthe same appearance as any perfect gold shell crown, and onewhich you may be sure will accurately fit the molar for which it Fig. .6. While soldering the caps also solder open tubes (turned up)to the buccal surfaces. The tubes should take the direction of thealignment wire. When apparatus is ready to be attached, cementthe first day, bicuspid bands only, to insure their not being pulledoff in placing the wire. At the next sitting the balance of the bands and the crownsare cemented. In placing the sprmg alignment wire, after cuttingit the proper length, place one end in the open tube of a molar,then spring it down under the bicuspid hooks, up and over the in-cisor hooks, down under other bicuspid hooks, and finally up intothe other molar tube, after which bend all the hooks and tubes inclosely upon the wire and polish off rough or projecting edges.
