IV. Mounting Procedure
A benefit of using the DENAR
Facebow is that multiple transfer jigs may be
used with only one measuring bow. In some
cases the mounting of the maxillary cast can
be delegated to the laboratory, involving no
loss of accuracy and no period of time with-
out facebow transfer capability in the dental
office. The laboratory can attach an articu-
lator index to its own DENAR
and mount the maxillary cast using only the
bitefork assembly from the dental office.
Each articulator index positions the bitefork
assembly on any DENAR
the relationship with the condyles recorded
on the patient is accurately reproduced on the
articulator.
Mounting The Maxillary Cast
Replace the incisal table on the articula-
tor with the articulator index (see Figure 11).
With the numbers on clamps #1 and #2 in
the upright position, secure the vertical shaft
of the bitefork assembly in the hole of the
articulator index. Tighten the finger screw on
the front edge of the index (see Figure 12).
Attach a mounting plate to the upper bow.
Be sure that the incisal pin is at the zero posi-
tion and that the upper bow is level and paral-
lel to the table top.
The position that the incisal pin sits on the
articulator index is determined by the type of
incisal pin being used. When using standard
incisal pins, the incisal pin should set on top
of the movable slide insert on the articulator
index (see Figure 13). When using the incisal
pin with the long centric adjustment, it sits
on the highest section of the movable slide
insert. In situations where the Slidematic
Facebow is being used with the same articu-
lator, secure the movable insert with a drop
of wax once the insert's appropriate location
has been determined.
