Figs. 92, 93, 94, and95, are given as suggestive both in the selection of teeth and theirarrangement. There is scarcely any limit to the capability of effecting mal-positions of the teeth of replacement, and this is especially true of Fig. those forms of substitution known as continuous-gum work, andin the use of celluloid, either process, by admitting of the use ofsingle, plain teeth, affording unlimited opportunities for the op-tional placement of the teeth. In the use of sectional gum teeth,many of the forms of dental irregularity have been faithfully Fig. 93.
