MFX'HANICAL FIXATION 23

Take an impression with the pins reaching into the
root canals, swage a wall, solder, and insert. But if
the articulation permits of the high wall, or if we can
correct the bite, it is better to save the pulps. The
single loose front teeth should be drilled and then
fixed by the split wire-ends.
It is good practice to perform the drilling on the
model a rlnv before.

When drilling, the head of the patient should be in
an upright position, in order that the drilling may
be performed in a horizontal direction.
Don't stop to think that the gold tips may be an-
noying from the sesthetic point of view. By means
of small cross-grooves, to be placed on each side of
the hole, the tips may be embedded and covered with
silicate cement.
In case several teeth in a row are lost, the sub-
stitutes are placed on the model, and the retaining-
wall made as if all the teeth were present.
