A practical treatise on artificial crown- and bridge-work . bridge the spacecaused by the loss of the right inferior bicuspids and first 256 ARTIFICIAL CROWN- AND BRIDGE-WORK. molar. The crow!i 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 telescoped 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 pass over the end of the crown; place the collar on thetooth, and with a block of wood and the mallet tap it to place FiQ. just beyond the free margin of the gum. This method willmake a close fit, as the collar will readily stretch all that isnecessary. With a sharp-pointed instrument mark the lengthof the crown and line of the gum margin, remove the collar,and cut it to the proper form as indicated. Then in a piece ofgold plate of the thickness used for caps form four little depres-sions of the general character of an impression of the molarcusps. An easy way to do this is to lay the })late on the leadanvil ; then with the ball on the end of an ordinary socket-handle and the hammer the depressions are made in a the collar on the plate, borax it, charge with solder, andheat till the solder flows. Cut off the surplus plate, and a per-fect cap for the molar is made. Place it on the tooth and takean impression, and thereafter proceel as before directed to make D1:T.
