48 THE TIGHTENING OF LOOSE TEETH

Badly broken down bicuspids should be restored
with porcelain. The following method affords most
satisfactory advantages, both for esthetic reasons (con-
spicuous appearance of a gold inlay) and because it
does not require devitalization of the pulp.
I adapt a narrow platinum band to the tooth, its
buccal part being narrow and inconspicuous ; on the
lingual and approximal sides it can be wider.

Fig. 32.

On the decayed part of the tooth cut the band,
and turn it inwards for securing the insertion of the
porcelain to be fused on. The band fitted, take a
pure gold impression of the cavity, put on the band,
attach both with wax, withdraw carefully, invest and
fire (Fig. 32).

Selection of Teeth.
In selecting teeth both colour and form are factors
of little importance. It is advised to select teeth in-
differently, and adapt them to the case in hand.
