A practical treatise on artificial crown- and bridge-work . buccal sides. The plate intended to connect the abutments wasthen adjusted in position as has been described. An impressionwas next taken and a model and articulation made. The cuspids REMOVABLE PLATE BRIDGES. 213 were then double-capped and collars formed on the molar double caps, pivots, collars, and plate were next solderedtogether. The artificial teeth were attached with vulcanite, thegum section being formed with pink. In order to avoid anywarping, which might readily occur in the construction of solarge a denture as this, the plate may at first be swaged up, asin ordinary artificial dentures, to cover the whole of the hardpalate. A shallow groove can be made around the palatal sur-faces of the teeth, and after the final soldering the plate can becut along the line of this groove, the portion covering the palatebeing removed. The groove will insure a close fit for the palataledge of the plate. Fig. In the case represented in Fig. 420 the natural teeth werevery short. The posterior approximal side of the molar wasdecayed to such an extent that the pulp was nearly exposed, andconsiderable irritation of the investing gum-tissue had beencaused by the clasp of a plate worn by the patient workingupward against it. The patient declined to have a plate madewhich would extend across the palate. The lateral was hardlystrong enough to support a permanent bridge. The molar wascapped, and a removable appliance constructed with a bandwhich slipped over the cap and rested on a shoulder on themesial side to form the posterior abutment. The lateral wasnotched and clasped for the anterior support. Figs. 421 and 422are two views of the appliance in position. 214 ARTIFICIAL CROWN- AND BRIDGE-WORK. Fig. 421.
