III. Slidematic Facebow Procedure
Mark the anterior reference point on the
patient's right side using the Reference Plane
Locator and Marker. The point is 43 millime-
ters above the incisal edge of the right central
or lateral incisors (see Figure 1). On an enden-
tulous patient, measure up from the lower bor-
der of the upper lip when it is in repose.
Cover the metal with two thicknesses
of baseplate wax softened in warm water
(approximately 135˚F or 55˚ C). With the
bitefork arm to the patient's right, place the
fork in the mouth, aligning the patient's mid-
line with the index notch, so that it is paral-
lel with the patient's coronal and horizontal
planes (see Figure 2). Be certain to obtain a
light indexing of the patient's maxillary arch
and then ask the patient to hold the bitefork
in place.
Attach the vertical shaft to the measur-
ing bow with the clamp marked #2 on the
patient's right and tighten the finger screw
(see Figure 3). It is necessary to tighten this
finger screw to secure the vertical shaft to the
measuring bow and also to avoid movement.
This same movement will occur after insert-
ing the vertical shaft in the articulator index
as shown in Figure 12. Be sure to tighten the
finger screw.
Loosen the finger screws on the clamps
marked #1 and #2 on the vertical shaft. With
your thumb, loosen the center wheel on
the top of the measuring bow and slide the
bow open to accommodate the width of the
patient's face. Assemble the facebow on the
patient by sliding the bitefork arm through
the hole in clamp #2 as the measuring bow's
earpieces are placed in the patient's auditory
meatus (see Figure 4). Tighten the center
wheel on the measuring bow and loosen the
finger screw on the anterior reference pointer.
Raise or lower the bow so that the pointer or
sight aligns precisely with the anterior refer-
