TUBE TEETH BRIDGE-WORK 33

In the case of dowel crowns, the place where the
splint is to be placed should be covered with a thin
layer of wax, into which the dowel crowns should be
pressed, after having been ground and moistened.
- Remove the teeth, and drill the marked spots of the
wire with a round or lancet burr of smaller gauge than
the pins.
Pass through each hole of the splint a pin, accord-
ing to the length of the tooth, put a ring of solder
round it, hold it with the soldering tweezers, and
solder in the Bunsen burner.
After the wire, covered with j)ins, has been put on
the articulator, try the teeth again, and grind down.
To find out the points of contact, long strips of
articulating-paper should be perforated and slipped
over the pins.
In case one of the teeth is not in its correct position,
bend its pin ; but it may be advisable to again flow a
little solder on the pin after it is bent, as the solder-
ing may have been weakened in the bending.
A short tooth should be lengthened by applying
Jenkins's prosthetic compound, k tooth is in correct
position when it fits well palatally and buccally.
Fitted thus, it will never cause any irritation.
The plaster model should be drilled through cross-
ways in several places with a lancet burr below the
wire on the approximal contact surfaces; binding
wire is passed through the V-shaped space of the
artificial teeth, and the bent- up wire fixed on the
model.
