Place the maxillary cast in the wax index
on the bitefork, close the articulator, and
mount the cast with stone to the mounting
plate (see Figure 14). Normally, a maxillary
cast support is not necessary, although one
may be used, if desired. Once the stone has
hardened, remove the transfer jig and replace
the incisal table in the articulator.
Mounting The Mandibular Cast
Attach a mounting plate to the lower bow.
A centric relation checkbite record is used to
mount the mandibular cast. With the maxil-
lary cast attached to the articulator and the
centric latch engaged, invert the articula-
tor and place the centric relation checkbite
record between the maxillary and mandibular
casts (see Figure 15). Stabilize the position of
the casts with either a rubber band or sticky
wax. Adjust the incisal pin to accommodate
the increased vertical distance caused by the
thickness of the centric relation bite record.
Double check to be certain that the condyles
are seated against the rear and tops of the fos-
sae, and using stone, proceed to mount the
madibular cast to the mounting plate on the
articulator (see Figure 16).
