Denar Mark II - Transferring the Facebow;Earbow to the Articulator

24
surfaces passes through the anterior
reference point as well as the posterior
reference points (fig. 45). Then with your
left hand pull the locator to the side so
that the reference rod is wedged in its
clamp. With the wrench in your right
hand tighten the clamp to secure the
reference rod in its support.
OPTIONAL The Anterior Reference
Pointer, Part No. D145, shown on page
58, is an optional accessory to the face-
bow which may be used in lieu of the ref-
erence plane locator (ruler) to adjust the
reference rod to the anterior reference
point marked on the patient’s face.
Now slightly retract the posterior refer-
ence slides so that they will not scratch
the patient’s face or hurt the ears as you
remove the facebow/earbow assembly
from the patient’s face. Once removed
repostion the slides to their original zero
positions. The facebow can now be
used to accurately locate the maxillary
cast on the articulator.
TRANSFERRING THE FACEBOW/
EARBOW TO THE ARTICULATOR
To prepare the articulator to accept the
facebow, set the immediate side shift
adjustments to zero, the progressive
side shifts to 5 degrees and protrusive
condylar paths to 30 degrees. The verti-
cal dimension of the incisal pin should
also be set to zero (fig. 46).
Next secure a mounting plate to the
upper bow of the articulator and a max-
illary cast support to the lower bow (fig.
47). The maxillary cast support fits onto
the lower bow of the articulator in lieu of
a mounting plate. It will help support the
weight of the cast and prevent deflec-
tion of the facebow.
When attaching a mounting plate to the
bow of an articulator always turn the
mounting plate in the same direction the
lockscrew is turned as the mounting plate
is secured to the articulator bow. (fig. 48).
