We may, if we will, make cramps more simple than those
we have spoken of. Draw out a platina wire to a middling
thickness, after which it must be flattened ; cut the cramps
of a sufficient length, before cutting out each piece, with a
cutting pincers.
There is another excellent way of making cramps, to which
it well fills up all the conditions
no objection can be made ;
it is a misfortune it can only be employed for teeth furnished
with talons or pivots. It consists in making screws of platina
wire of a convenient size, then cut each vice about two lines
in length ; then prepare, with a file, the end which corres-
ponds to the summit of the talon, and a hole is pierced in the
middle. This hole is made for receiving a pin which is also
soldered to the plate. Seethe manner of mounting teeth with
talons, Section V. paragraph 8. This same hole which I
have carefully bored through, serves again to pass through a
screw, which permits me to mount, sometimes, incorruptible
teeth on gold bases.
§ xiv. Manner of Modelling Incorruptible Teeth.
The operation which has for its consideration the model-
ling of the teeth, appears to be, at first sight, of the least im-
portance, and of no moment ; it is, nevertheless, very essen-
tial, and requires to be well done. We shall give different
precautions, and to which much attention should be given.
Before modelling the teeth, the paste should be made
very unctuous, well kneaded with the fingers ; and, that it
may not become too liquid, it is necessary to put a certain
quantity on a dry plate, that all the humidity may be ab-
sorbed ; then they fill all the moulds or matrices with one of
the pastes which we have prescribed. It is a practice, by
means of u little square piece of platina, to give to the poste-
