ROTATED TEETH. 725

The plate may be di.speused with by attaching the rubber band to
some other tooth for anchorage
(Fig. 6Q()), or to a lingual bow
as shown in Fig. 667.

Plate and band for rotating Two Magill bands for rotating.

Extra force may be gained in rotating by passing the rubber once
around the tooth after attaching it to the hook, as a rope is wound
around a windlass.
If it be necessary to rotate a tooth outwardly, attach bands with
tubes to any two convenient teeth such as canines or bicuspids ; extend

a wire bow from one to the other, as in Fig. 668, and use this as a point
of attachment for the rubber band. The ends of the bow are prevented
from passing too far through the tubes by the bending in bayonet shape
or by pinching the posterior ends of the tubes. If the canines are used
for anchorage, solder the tubes vertically to the bands and bend the
ends of the bow at right angles.
Force may be applied to the tooth from two directions by making
hooks on both sides of the band and extending a rubber band or ligature
from one hook to a labial bow and from the other to the lingual bow, as
shown in Fig. 669, A and /;.
