Fig. 101. Photograph of the teeth in normal occlusion, including the alveolar processes and
bones. This is given as a study of the normal relations of the cusps of the teeth of the upper arch
to the embrasures of the lower, and the relations of the cusps of the lower teeth to the embrasures of
the upper. It will be seen that among the bicuspids and molars this relation is constantly such as to
force food through these embrasures in chewing.
