A practical treatise on artificial crown- and bridge-work . with a mallet until the collar touches the gum, when it -hould be marked to indicate the necessary trimming to conform it to the gum contour.

MELOTTES METHOD. 533 tenth of an inch in width, the collar is again driven on, and willappear as seen in Fig. 473. A stump corundum-wheel is thenused to grind a shoulder on the lingual surface of the tooth,grinding also the edges of the collar flush with the collar is again removed, and a piece of thin platinum plate,about No. 32,-sufficient to cover the lingual surface of the tooth,is caught on this lingual edge of the collar by the least bit ofsolder, and all put in place on the cuspid (Fig. 475). Theplatinum should now be burnished on to the shoulder, and overthe tooth and collar to the extent shown by the lines in Fig. 475. Fig. After trimming to those lines, and careful replacement andburnishing on the tooth, the collar and half-cap are removed,filled with wet plaster and marble-dust, and the platinum solderedto the gold. It is then placed on the tooth, burnished into all theinequalities of the tooth, very carefully removed, invested, andenough solder flowed over the FlG. 475 FlG. 476.

I have feared that a detailedstatement would imply a long < 1 • =*** and tedious process, but I have often made such collars in less than an hour, and in any casetime must be made subservient to exactness of fit and adaptationto the end in view. In the preparation for fitting a collar on the first molar (), I should have wedged or otherwise separated it from thesecond molar, so that a piece of sheet brass might be put inplace, as shown by Fig. 477, and an impression tak
