J32 THE TIGHTENING OF LOOSE TEETH
The abutments prepared, take a plaster impression
and mount the whole on the articulator.
The tube teeth are ground, crowded together with
contact points and V-shaped openings for rinsing.
This done, make through the tubes of the teeth little
holes on the plaster model with a pointed burr.
After removal of the teeth, these marked dots indi-
cate the position of the splint that is to be made. The
wire, which has been made half-round, or if necessary
oval, is bent so as to lie on the jaw along the dotted line.

Fig. 24. Fig. 25.
Bend up the wire ends to the abutments at right
angles, and flatten them so that they may lie on the
abutments. These places serve later as rinsing
openings for the patient to keep it clean (Fig. 24).
With sticking-wax fix the wire on the abutments.
To place the tube teeth again in their previously
ground places, deepen them by making a groove so that
they sit saddle-like on the half-round or oval wire.
With sticking-wax fix the teeth, examine the articu-
lation, and through the tubes of the teeth mark on
the splint the points for the pins.
