^8 THE TIGHTENING OF LOOSE TEETH

If in this case the wire splint be bent when intro-
duced, it is a matter of no importance.
The bridge placed in the mouth, strong pressure
on the splint by means of pliers may restore the
tension as it was before.
If the abutments to be connected are an inclined
molar and a root, which would render impossible the
setting of a bridge without material destruction of
the molar, make over the inclined tooth a half-cap

with a pin. After first tying it on, allow the wire
end to extend over the root, and drill the flattened
wire above the opening of the root so that the pivot-
plate fits in exactly. Then the pin is to be placed in
the opening for its final closure (Fig. 28).
For preserving short loose roots, either for the
sake of the arch or to prevent absorption, the pins
for the tube teeth may be allowed to reach through
the half-round wire into the nerve canals of the
roots.
