Figs. 350-364. A series for the illustrati(in of the r^o oi iion-culii.sivc' {;;iii(] dii the {^in^ival wall
of proximo-occlusal cavities in the bicuspids and molars.
Fig. 35G. A mesio-occlusal cavity with a flattened cylinder or mat, laid in loosely. It is seen to
be long enough to be pressed tightly between the buccal and lingual walls of the cavity.
Fig. 357. The mat or flattened cylinder is pressed well into place, but has not been severely
condensed.
Fig. 358. Instead of the single flattened cylinder made for the special purpose, cylinders of suit-
able size and length may be used, as shown in this figure.
Fio. 35fl. The two cylinders shown in Figure 358 may be pressed a little to either side and a
third cylinder added and tlie three pressed into place with a broad condensing point.
Fig. 300. Three cylinders pressed together moderately. From this point forward the cylinders
and the flattened cylinder or mat would be handled similarly in building with cohesive gold. One or
more additional layers of either may be used if desired, but in that case, more severe condensation
would be necessary before adding cohesive gold.
