If, after somewhat protracted swaging, the plate is not con-formed perfectly to the face of the die, another and unused coun-ter should be substituted for that in use; and, indeed, it is betterin all cases to have duplicate copies both of the die and counter inreserve with which to complete the swaging, inasmuch as moreor less deformity of both swages unavoidably occurs before theplate is brought into very accurate coaptation with the die. The.

The margins of theplate adjoining the necks of the teeth should be permitted eitherto lie closely to them, or should be cut away, leaving a spaceequal to a line or more between the plate and the teeth; for ifbut a very narrow line of uncovered gum remains at these points,injury to the parts immediately surrounding the necks of theteeth is more liable to occur from strangulation of the interposedgum, than if the plate were further removed from the teeth orrested directly against them. Adjusting and Strengthening the Projections or Tongues ofthe Plate.—If the portion of the plate which passes in betweenthe remaining teeth is quite narrow, as where but a single toothis to be supplied, it should be strengthened by wiring the edges ordoubli
