FIXATION OF LOOSE BICUSPIDS 25

In filled teeth the fillings should be removed, and
replaced by inlays that are connected by soldering.
If there is a space, in loosened molars I raise the
bite by mounting crowns ; in the case of bicuspids, a
Carmichael crown is advised. By means of a carbor-
undum disc, I cut a groove both across "ihe fissures of
the tooth and vertically on both sides (Fig. 20). Next
I swage a pure gold cap, fit it in the mouth, press the
gold firmly into the groove, and twist a ligature firmly
round the crown for securing a perfect fit of the pure

gold crown. The groove filled with solder, a thin wire
should be let in and soldered.
For strengthening, a strong gold-plate is soldered
to the side of the pure gold (Fig. 21), but only so far
as not to extend beyond the lower margin of the pure
gold.
In case the bite does not admit of the use of a Car-
michael crown, it may be modified. No gold-plate
should be placed on the buccal cusp, but a strong
gold wire embedded in the transverse groove for
stiffening the crown, like a stirrup.
