METALLIC BASE WITH RUBBER ATTACHMENT. 11/

I'^iG. 68. Fig. 69.

Fig. 70.

An excellent instrument for this purpose is that devised by
Dr. H. Gaskill, which is illustrated in Fig. 69. The
J.
form of loop or attachment given by this instrument is
shown in Fig. 70.
\\nien a cast metal plate is employed, loops or pins are
not needed, as sufficient anchorage is secured by cutting out
the wax on the labial surface and from between the teeth
(in fact, from every point where it is desirable to have the
rubber) before Uaskhig for the casting process. After the
plate has been cast and finished, the rubber may be packed
and the case re-flasked, vulcanized, and finished in the usual
manner.
