    ing natural teeth, a roll of cotton should be placed between the crown and the opposing teeth, and a steady and firm pressure of the jaw in normal occlusion maintained until the cement has crystallized, in order to prevent any possible displacement. The same precautions incident to the removal of all excess cement should then be observed with equal tare, and before dismissing the patient it should be carefully and finally noted that the crown does not occlude too hard, as subsequent discomfiture will invariably result if this con- dition exists. If any doubt exists as to the accuracy of the re- Insuring Accuracy of lation of the cervical edge of the crown to the per- Adaptation to Root. iphery of the root, some means of insuring a close joint between them should be observed. This may often be aided materially-by slightly reducing the circum- ference of the edge of the band with curved or small, pointed pliers, just ' W an —— Nth WH Wi Wi ANN Nk NAAR AA) AAW) i ) ) AN NA iy Fig. Cae. previous to the final mounting, as it may have become somewhat en- larged, by stretching, in the fitting and preliminary trials. The use of a smooth foot plugger adjusted to the automatic mallet may also be found useful, and particularly along the buccal edge, after the crown has been mounted: and the approximal edges may be brought into closer contact by inserting a small amalgam burnisher into the inter- proximal spaces, and exerting some little effort in this direction. Hither a suitable burnisher, such as is illustrated in Fig. 222, or the foot-plugger, may often be employed to good advantage upon the lingual surface, but in the use of either, some little care should be observed to avoid produc- ing sharp angles at the corners, and yet to secure a close adaptation and particularly at the bifurcation of the roots. In extreme cases of ill adaptation or of exceedingly constricted necks, a good result may often be obtained by encircling the crown with a piece of German silver, or copper wire, from 24 to 26 gauge, passed through the interproximal spaces, and the ends then twisted from the
