Many other points in enhancing the appearance of arti-

the thoughtful student. The accompanying illustrations,
Figs. 15 to 19, inclusive, are given as typical studies.

in sectional blocks, the proper shape and contour may be
given to the denture. But these teeth are not susceptible
to as natural and artistic arrangement as the plain teeth.
The latter, however, can only be employed where the teeth
