Shoulders on the Anterior Teeth are sometimes desirable, especi-ally on the superior cuspids at the point of occlusion with thelower teeth. A shoulder can be made by melting gold plateinto the form of a small ball or globule, then flattening it outand soldering it against the backing. Another method is to attach withwax transversely across the backingin proper position a strip of goldplate as shown in Fig. 316, and thenflow in gold to the line A, by spe-cially investing or in the soldering ofthe bridge. Soli/I Gold Crowns.—In a c-lose articulation, when the patientprefers strength to appearance, the bicuspids and molars shouldbe made of solid gold. They are constructed by stamping upthe cap {A, Fig. 317) representing the grinding-surface (seepage 97), and then adjusting and cementing with wax a pieceof i»late cut and shaped to form the front and sides (B), whichis then invested and tilled in with gold solder, or, if pure gold hasbeen used in the sections of the crown, with 18- or 2
