A practical treatise on artificial crown- and bridge-work . ext, placethe appliance on the cast (Fig. 500), holding it in position with 256 ARTIFICIAL CROWN- AND BRIDGE-WORK. Mu ilar. The crown of the right cuspid is nearly gone, but theroot is sound and capable of supporting one end of the other end will be attached to the second molar, which isa sound tooth. Prepare and band the cuspid root as before;dress off the second molar crown until it is slightly smaller thanthe neck, and shorter at the occluding surface, so as to permita cap to be teleseoped over it, and take the measure of thecrown with the binding-wire. Select a suitable seamless collarof sufficient width to extend from the neck to a little beyond thegrinding-surface, and drive it up on the proper mandrel to getthe general shape, but not the full size required to fit the tooth,leaving it so that the edge having the larger circumference willjust pates over the end of the crown; place the collar on thetooth, and with a block of wood and the mallet tap it to place Fig. just beyond the free margin of the gum. This method willmake a close lit. ;is the collar will readily stretch all that isnecessary. With a sharp-pointed instrument mark the lengthof the crown ami line of the gum margin, remove the collar,and cut it to the proper form as indicated. Then in apiece of-old plate of the thickness used for caps form four little depres->i«111^ of tin general character of an impression of the molarCUSps. Aii easy way to do this is to lay the plate on th« leadanvil; then with the ball on the end f an ordinary socket-bandle and the hammer the depressions are made in a moment,(lamp the collar on the plate, borax it, charge with solder, and heal till the solder (lows. Cut oft the surplus plate, and a per-fect cap for the molar i< made. Place it on the tooth and takean impression, and thereafter procee I a- before directed to make DET.
