In any case I should cover the enamelcutting-edge with gold, and then dress off only so much as shouldbe found necessary for occlusion (Fig. 4). If the incisors and cuspids Fig. 6. Fig. are all abraded, I should contour the edges also as shown in Fig. 5,which represents the finished filling. Indeed, I should in somecasesdress off the lower incisors round and smooth, because the wear ofsmooth enamel on gold would be much slower than that of tooth ontooth. It is obvious that this method of operating is applicable to teeththat have been still further abraded, or where there is a complication 54 THE DENTAL COSMOS. with both mesial and distal approximal cavities as seen in Fig. a like instance two anchoring pits are made in the cutting-edgegroove, but when that is impracticable, the groove may be so shapedas to make the connecting filling a very strong bond of a completed filling is shown in Fig. 7. The matrix is a valuableaid in the building and contouring of teeth which have but thin shellsof enamel left, and the described method of procedure is adaptable towhatever kind of matrix may be preferred.
