I. Rationale for Development
Based on in-depth analysis of the
facebows on the market engineers in
conjunction with several leading cli-
nicians and educators prepared a list
of criteria for the development of this
new facebow.The SlidematicFacebow
was designed to satisfy the following
requirements:
• An accurate earbow that moves
straight horizontally for different
facial widths, unlike the caliper type
that moves off the vertical axis.
• Aminimalnumberofpartsandfin-
ger screws to permit a facebow reg-
istration to be taken in less time.
• The ability to send the bitefork
assembly (without the measuring
bow) to the laboratory, preventing
damage to the bow in transit.
• Easeofmountingthemaxillarycast
by not having to transfer the measur-
ing bow to the articulator.
• The capability of taking multiple
facebow records at the lowest pos-
sible cost through the use of only
one measuring bow and different
bitefork assembly for each case.
II. Benefits and Features
Facebow Transfer
The facebow transfer procedure
establishes the relationship of the max-
illary dentition to the horizontal refer-
ence plane so that the maxillary cast
may be mounted on the articulator in
the correct anatomical position. The
Slidematic Facebow provides a fast,
easy and extremely accurate means of
transferring the proper anatomical rela-
tionship to the articulator.
Benefits and Features
• Theprecisionmanufacturingofthe
unique “speed-slide” gear mecha-
nism makes it very easy to assemble
the bow on the patient.
• Therightandleftarmsofthemea-
suring bow are geared to precise
equidistant movement from the cen-
ter of the bow.
• Thescaleonthemeasuringbowrep-
resents the patient’s intercondylar
distance (not the interbow distance)
foreaseinsettingarticulatorshaving
this adjustment.
• TheSlidematicFacebowcanbeused
onallDENAR®articulators. It also
adapts for use with SAM®, Whip
Mix®,andHANAU™articulators.
• Thebowusestheexternalauditory
meatus reference point for determin-
ing the arbitrary hinge axis location.
• Thebuilt-inreferencepointeraligns
the bow with the horizontal refer-
ence plane.
• The built-in sight can be used to
view the anterior reference point.
• The measuring bow should not be
mounted on the articulator during the
transfer procedure. The bow, when
detached from the vertical shaft, can
be used again immediately with the
additionaltransferjigs(verticalshaft,
bitefork assembly and articulator
index). In this manner, the maxillary
casts may be mounted at any time.

• Inonestepthebiteforkassemblyis
secured to the articulator index and
maxillary cast can be mounted to the
articulator.
• Allfinger screwsare easilyacces-
sible from the front.
• Theprocedurescanbereadilydel-
egated to auxiliary personnel.

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-

ence point (see figure 5) and tighten clamp
#1, then clamp #2 (see Figures 6 and 7).
Whentightening clamps#1and#2,care must
be taken not to displace the bow to either
side by having the vertical shaft rest on the
fingers as shown in Figure 6. The patient’s
inter-condylar distance is the measurement
indicated on the scale (see Figure 8). Record
this measurement.
Loosen the finger screw on the measur-
ing bow, slide the bow open, and remove the
entire facebow from the patient.
Detachthemeasuringbow fromthetransfer
jig by loosening the finger screw (see Figure
9). Having completed the procedures involv-
ing the patient, the bitefork assembly (see
Figure 10) may be labeled with the patient’s
name and set aside while the measuring bow
portion can be used with an additional bite-
fork assembly for the next patient.
Note: The metal bitefork, vertical shaft and
earpieces can be sterilized in an autoclave
EXCEPTfortheblackfingerscrewsonthe
#1 and #2 clamps. Remove the finger screws
(and spacers) before autoclaving or use cold
sterilization.
Sterilize bitefork before each use.

AbenefitofusingtheDENAR®Slidematic
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®articulator
and mount the maxillary cast using only the
bitefork assembly from the dental office.
Eacharticulatorindexpositionsthebitefork
assemblyonanyDENAR®articulator so that
the relationship with the condyles recorded
onthepatientisaccuratelyreproduced onthe
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.

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.
Acentric 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 maxillaryandmandibular
casts(seeFigure15).Stabilize theposition 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).
