eneral form of the cavity and wedging
within a certain limit, and not by cohesion of the different parts. For
a time tin cylinders were prepared and put on sale at the dental depots.
As far as we are aware, the first tin foil made use of in operative
technics was by Dr. F. S. Whitslar, who removed a disk of German silver
from an ivory knife-handle in 1845, then used hand pressure to fill the
cavity with tin. In the college course of operative technics tin foil
can be used, almost to the exclusion of gold foil, to demonstrate the
manipulation of both cohesive and non-cohesive gold. Shavings scraped
from a bar of tin are also useful in operative technics; they are more
cohesive than foil.
