A practical treatise on artificial crown- and bridge-work . ps, which were then, by means of oxyphosphate cement, fixedfirmly on the teeth. Suitable plate teeth were selected, fitted,backed, and hard-waxed in place between the telescopingcrowns. After hardening the wax with cold water from a tooth-syringe, the pieces were carefully removed, invested, and sol-dered. The two completed bridges were easily replaced on orremoved from the supporting capped teeth, and their appearance 196 ARTIFICIAL CROWN- AND BRIDGE-WORK. when detached is correctly shown by the illustration, Fig. 391,which also shows the capped teeth and stumps. The figure like-wise shows the results of the novel method employed in crown-ing the incisors. Gold collars were fitted tight on the necks ofthe incisor stumps, and the new-style porcelain caps adjusted inthe collars, and set in the oxyphosphate cement which had beenpacked into the collars ; thus at the same time fastening thecollars on the stumps and the caps in the collars, as showncompleted in Figs. 391 and 392. Fig. • Fig. 392 illustrates the finished crowns and bridges, whichlatter were Becured in position by placing a small piece of gutta-percha in <-a<-li of the telescoping cap crowns, which were thenwarmed and carefully pressed in pla<-e,—the gutta-percha fillingonly the spaces between the flat tops of the caps of the naturalteeth and cusped caps of the brid. DETACHABLE AND REMOVABLE BRIDGE-WORK. 197 • Whenever, for repair or for any other purpose, it shall be-come desirable to remove one of the bridges, that may readilybe done by applying a hot instrument or hot air to the caps tosoften the gutta-percha sufficiently to permit the telescopingbridge to be taken off. A full upper vulcanite denture was made to replace the oldone, which, by improper occlusion, had thrown the full force ofmastication on the anterior teeth of the lower jaw, and produced Fig. 392.
