ceeding blows of the condensing appliance. This will insure that no uncondensed areas in the gold remain, resulting in the attainment
of maximum density, and we shall have used the resiliency of the dentin to advantage in that the frictional resistance so created will prevent loss of the restoration, and, through perfect adaptation, the cavity will be perfectly sealed.
After the foregoing procedure, a concavity of the surface of the mass of gold will probably be developed. This is to be desired as it will mean that the margins of the gold will reach the beginning of the bevel of the cavosurface angle in advance of the main body of the gold and this, in turn, will make it possible to lap the margins of the cavity ahead of the body of the filling, thus helping to insure sealing of the cavity. If this is disregarded, it will be found, on completion of the restoration, that addition of gold to the margins will be necessary. It will soon become evident that this cannot be easily accomplished with satisfaction. The mistake should not be made of attempting to cover all margins of the cavity too far in advance of the main part of the restoration. Such a procedure would be illogical.
If the restoration involves a contact point, a special effort should be made to secure the best possible condensation in this area, to prevent too rapid wearing at this point. Again let me emphasize the advisability of securing separation of the teeth in making restorations wherein the contact is involved. The necessity for this can now be appreciated.
The necessity for careful attention to
