Such an articulation may be more thoroughly secured by
removing the sharp points from the cusps of the teeth.
This will also largely o\'ercome the " clattering " so often
noticed in artificial teeth.
Faulty Articulation.—When, in a finished denture, the
articulation is found to be slightly faulty, the false touching
points can readily be recognized and removed with the
corundum wheel. When, however, the articulation is found
to be so far out of the way as not to ])ermit of satisfactory

occasionally occurs to the inexperienced, and should prove
to them a wholesome lesson. It is always better, as has
been previously suggested, to try the teeth in the mouth
while they are yet on the wax plate, when any imperfection
can be easily remedied.
Shaping the Cutting Edges.—In articulating the teeth,
particularly those in the anterior part of the mouth, it is
frequently advisable to so cut and shape the edges that
they could hardly be recognized as the same teeth.
Take, for instance, a person of the sanguine tempera-
