HANAU WIDE VUE ( MODEL 183 & 184 )
• Hanau- brand articulators were
first introduced to the dental
profession in 1921 by RUDOLF
HANAU
• These are the newest Hanau
articulators
• These are arcon in nature
• The only difference is that the
upper and the lower members can
be separated in model 184 due to
open condylar track
• The Horizontal condylar guidance
is adjustable from -20º to + 60º
• The bennett side shift is
adjustable from 0º to 30º

Allows adjustment to replicate avg. mandibular movements = Class 3
• Simulates condylar pathways by using avg. values for all or part of the
motion
• Permit eccentric + only part of condylar motion , hence semi adjustable
Condyles attached to
lower member
Condylar guides to
upper member
Same as natural jaw

CONDYLAR GUIDANCE
● The condylar guidance are the control centers of the articulator and they adjustably
assimilate the multiple function of the glenoid fossa
● The condylar track may be adjustably inclined on the horizontal transverse axis from a
“zero” to a “ +60 ” degrees to a “ – 20 ” degrees.
These inclinations are termed the protrusive inclination and simulate the patient’s superior
wall of fossa
• It may also be adjusted on the
vertical axis from a “zero” sagittal
to “ 30º ”
This is termed as the progressive
Bennett angle and corresponds to the
medial wall of patient’s fossa

Bennett angle
● The angle formed by the sagittal plane and the path of
advancing condyle during lateral mandibular movements
● This corresponds to the medial wall of the patient’s fossa
● Avg. value = 7.5º – 12.8º
● Bennett angle (L) = H/8 + 12
LATERAL CONDYLAR GUIDANCE

DUAL - END INCISAL PIN
● The incisal pin serves as the forward
control of the articulator.
● It maintains a vertical stop and provides a
stylus contact for the excursive movements
of the articulator against the various
inclined guiding surfaces of the incisal
guide.
● 5 additional lines calibrated in millimeters
extend on either side thereof
● These lines are used for recording or
altering the vertical dimension

● Two annular grooves, appear on the Incisal Pin at 37 and
54 mm below the Frankfort Horizontal Plane. These
grooves form arbitrary vertical landmarks for alignment
of the incisal edge of the maxillary centrals when
making a Facebow transfer.*
● The 37 mm line is based in part on the Bonwill Triangle
and results in a generally horizontal appearing plane of
occlusion.
● The 54 mm line forms an average landmark for
alignment of the incisal edge of the upper centrals, when
making a Facebow transfer.
*This reference line is based on the research study by Frank R.Lauciello, D.D.S., and Marc Appelbaum, D.D.S., "Anatomic Comparison to Arbitrary Reference
Notch on Hanau™ Articulators," Journal of Prosthetic Dentistry, December 1978, Volume 40, Number 6, Pages 676-681
 3rd point of stability

ADJUSTABLE INCISAL GUIDE
● Provides adjustment to anterior guidance.
● The Incisal Guide rotates antero-posteriorly from a horizontal "zero" degree to a 60 degree positive inclination of
protrusion which is then secured by the small Locknut. The central guiding table is 5.56 mm wide and forms the
inclined surface for the protrusive guidance of the Incisal Pin.
● Separately adjustable Lateral Wings elevate by a Thumbscrew from a "zero" horizontal to a 45 degree incline and
are fixed by a Thumbnut.
• An anterior slot, in the Lower
Member, allows repositioning
of the Incisal Guide. Adjust and
lock the Guide at a "zero"
horizontal and slightly loosen
the Platform Lock screw. Slide
the Platform antero-posteriorly
to align the chisel end of the
Incisal Pin with the "zero"
indicating line on the Lateral
Wings.

ORBITAL INDICATOR
● Some articulators are equipped with an Orbitale Indicator. This "crescent" represents
the patient's infra-orbitale notch and is the anterior reference landmark of the
Frankfort Horizontal Plane.
● When used with an Orbitale Pointer on a Facebow it provides an anatomical vertical
orientation for the upper arch, obviating the use of any average reference lines on the
Incisal Pin

MOUNTING PLATES
● To attach upper and lower casts to
upper and lower members of
articulator
● Has elongated luting slots – for a
secure adherence of gypsum
mounting
● Center domed brass insert which is
internally threaded for attachment of
upper and lower members.

ARTICULATOR PREPARATION
(ZEROING OF ARTICULATOR)
● Adjust the protrusive inclination of both condylar guidance
to 30°.
● Adjust the Bennett angles of both condylar guidance at 30°.
● Adjust the Incisal Pin to align the mid-line calibration to
the top edge of the upper member.
● Adjust the Incisal Guide to a 0°.
● Tighten the Centric Locks, to restrict the articulator to
opening and closing movements only
● Slide the Platform to align the Incisal Pin contact over the
“zero” indicating line on Guidance and tighten Platform
Lock screw.
● Articulators with Protrusive-Retrusive feature ONLY must
be adjusted to a “zero” centric
● Apply a thin coating of petroleum jelly to all surfaces of
the Articulator that will be exposed to the stone mounting
media.
● Firmly attach a Mounting Plate to the Upper Member.

Whip Mix Hanau Spring-Bow Earpiece
Facebow
● The HANAU™ Spring-Bow is an earpiece-type facebow,
used to capture and record the patient’s maxillary arch
and its relationship to the external auditory meatus.
● It is capable of preserving this clinically accepted
relationship and transferring it to a HANAU™ or other
brand articulator.
● For indirect or direct mounting to all HANAU and DENAR
Articulators (except HANAU Model 145)

BENEFITS:
– Automatically centers for outstanding accuracy and patient comfort.
– Unit may be sterilized by steam autoclave for cross-contamination control.
– Transfer clamp attaches directly to the articulator which allows for multiple
measurements with only one facebow required.
– Allows for transfer clamp assembly to be used with DENAR®, SAM, Whip-Mix
articulators.
– Facilitates in aligning the measuring bow with the horizontal reference plane.

TRANSFERING TO ARTICULATOR
Direct face-bow transfer After making the face-bow record, the
ear pieces of the spring-bow were used for suspending the bow
over the condylar shaft ends of the Hanau™ Wide-Vue
articulator. The anterior elevator was adjusted so as to position
the top of orbitale pointer on the spring-bow to the underside of
the orbitale indicator on the articulator and then was secured by
the thumbscrew. The bitefork index was checked to be
adequately supported by cast support before placement of the
maxillary cast and plaster mounting to the articulator [Figure 2].
Indirect face-bow transfer After the direct transfer had
been completed, the spring-bow was unscrewed from
the transfer assembly. The mounting platform was
secured on the lower member by the cast support. The
transfer assembly was secured onto the mounting
platform, and the cast support was raised to support
the bitefork index following which the maxillary cast
was mounted [Figure 3].

GOTHIC ARCH
● “Gothic” name originates from ancient Gothic peoples’ houses
● Important feature of gothic architecture is the pointed arches

GOTHIC ARCH TRACING
● Graphic methods are either intra-oral or extra-oral,
depending upon the placement of the recording
devices
● Extra oral tracing are also referred to by 2 other
names :-
 gothic arch tracings and
 arrow point tracings
● The Hight Tracer, 1986 – it is a four component
assembly which consists of an upper bearing plate,
lower bearing plate with central screw, a scriber
point to be attached to the upper rim and a tracing
platform which extends in forward and is attached
to the lower rims

EXTRA ORAL TRACING TECHNIQUE
● After taking facebow records, it is transferred to the articulator and mounting of the maxillary cast
is done. Then, with tentative CR records, mandibular cast is mounted
● The upper bearing plate is heated and waxed to the maxillary rim, making it flush with the occlusal
plane
● The lower rim is reduced by 3 mm and the lower plate is fixed to the mandibular rim

● The scriber is attached to the maxillary rim and lower tracing platform is waxed to the mandibular rim.
● The upper and lower tracers are made parallel
● Seat the patient with head upright in a
comfortable position
● Intraorally seat the record bases with the
attached devices
● Retract the and conduct training exercises
by instructing the patient to move the jaw
forward, backward and to left and right
side

● When the patient is proficient in
executing the movements,
prepare the tracing plate. The
tracing plate is covered with a
thin layer of precipitated chalk
and denatured alcohol or soot.
● The subject is made to perform
protrusive and lateral movements
till a gothic arch tracing with
sharp apex is obtained
● A protrusive tracing point is
marked, 6mm away from apex.
● A plastic sheet with a hole
corresponding to the apex and
the protrusive tracing points is
mounted over the platform of the
tracer.

● Prior to making records, small nicks are made
in the maxillary and mandibular rims which
assist in repositioning the records in their
correct positions later.
● For making the centric and protrusive records,
the patient is asked to hold the pin in the
drilled holes to stabilize the position while
injecting quick setting plaster between the
rims.
Eccentric records are made at 6 mm
because-
• The normal functions are performed
within 6 mm
• The articulator will be optimally sensitive
to be programmed for a horizontal angle
and bennett angle only at 6mm distance
or above
• Condyles will be positioned too anteriorly,
beyond 6mm, resulting in a reduction of
horizontal angle while programming the
articulator.

Centric interocclusal records –
● It has to be perforated, there should be
no gap between the split cast and the
centric should be properly placed with
pin in designated slot on tracing
platform.
Protrusive interocclusal records-
● Elevate the incisal pin and loosen the
thumbscrews of condylar guidance. Seat
the protrusive record and note the
reading on the horizontal condylar
guidance.
● Then calculate the, L=H/8+12
Purpose of the protrusive jaw relation
record is to adjust the condylar
elements of the articulator so that they
will present inclinations which are, as
nearly possible, similar or equivalent to
those in the temporomandibular
articulation
It allows the clinician to extrapolate all
mandibular movements : maximum
intercuspation (MIP), protrusive end to
end, lateral excursive and the pathways
to them

Intra – oral Extra – oral
The intra oral tracings cannot be observed
during the tracing
Extra oral tracings are visible and can be
observed during the tracing
Since the intraoral tracings are small, it is
difficult to find true apex
Tracings are larger and so the patient can
be directed and guided during the
movements
The stylus cannot be observed in the apex
of the tracing. If the patient moves the
mandible before the occlusion rims are
secured, the accuracy of the record is
destroyed
The stylus can be observed in the apex of
the tracing during process of injecting
plaster between the occlusion rims

Classifications of arrow point tracings
TYPICAL
● Well defined apex with a
symmetrical left and right lateral
tracings
● The mean gothic arch angle is about
120 º
● Reflects a healthy TMJ without
interferences in condylar path and
balanced muscle guidance
● Symmetrical form indicates an
uniform movement of the condyle in
fossa and distal slope of eminence
with symmetrical balanced muscle
guidance
FLAT FORM
● The gothic arch angle is >120
º
● It has more obtuse left and
right lateral tracings
● It signifies a marked lateral
movement of condyle in the
fossa
ASSYMETRICAL FORM
● The left and right lateral
tracings meet in an arrow
point; however their
inclination to the protrusive
path is not symmetrical
● One of the lateral tracing is
shorter
● Indicates an inhibition of the
forward movement because
of restricted movement of
one joint; either in left or
right joint

APEX ABSENT / ROUND
FORM
● Incomplete
retrusive
movement
● Movement of
record bases
MINIATURE ARROW POINT
● The extension of tracing is very
limited
● This can be due to restricted
mandibular movements
improper seating of record bases,
and painfully fitting record bases
during registration
● Also an indication of a long
period of edentulousness with an
inhibition in condylar movements
DOUBLE ARROW POINT
● It is a record of habitual; and
retruded centric relation
● It is also seen when vertical
dimension is altered during
registration
● Allow patient training and
repeat till a single gothic arch
is obtained

DORSALLY EXTENDED ARROW POINT
● The protrusive path extends
beyond the apex of the gothic
arch
● Signifies a forced strained
retrusive movement of the lower
jaw
● Sometimes caused by the
forward displacement of upper
occlusal rims or backward
dislodgement of lower occlusal
rim while removing them from
the mouth
● It can also occur when head of
the patient is tilted too far
posteriorly.
INTERRUPTED GOTHIC ARCH
● Break or loss of continuity of
lateral incisal path of gothic
arch.
● This happens due to
posterior interference at the
heels of occlusal rims during
lateral movements
● Check for posterior
clearance before recording
ATYPICAL FORM
● Protrusive component does
not meet at apex but on
one of the lateral path
● This may happen if faulty
muscular pattern is present
due to parafunctional
habits
● Also seen in very old
edentulous patients, who
are using complete denture
with incorrect centric
relation.

WHY GOTHIC ARCH TRACINGS?
● Verifies centric relation position most accurately
● Store the records for future
● To set the horizontal condylar guidance

LIMITATIONS OF GRAPHIC METHOD
● It is preferred in good edentulous ridges with normal inter-arch relation
● Arrow point tracing is difficult in excessively resorbed and flabby ridges
as it causes instability of the recording bases and this restricts its use.
● It is not indicated when there is inadequate inter arch distance, as it is
difficult to accommodate the tracing device without increasing the
vertical dimension
● A sharp arrow point cannot be traced in persons with TMJ arthropathy.
In these instances conventional wax closure method is the alternative
choice

HANAU H2
Horizontal Condylar Guidance

CARE AND MAINTENANCE
CLEANING-
● Use a mild soap and water solution with the aid od a brush to dissolve accumulations of wax and to wash away
carborundum grit.
● Then air dry and lubricate. DO NOT use strong detergents, alkalis, gasoline or naphtha as cleaning agents.
LUBRICATION-
● Lubricate the working and bearing components with a thin film of sewing machine or high speed hand piece oil. Wipe
off excess oil to prevent accumulation of dust or grit
● A thin coating of petroleum jelly must be applied to all articulator surfaces that will be contacted by the gypsum
mounting material.
STORAGE-
● Store the articulator in a clean, dry atmosphere free of plaster and carborundum
dust; away from acids, alkalis or corrosive medicaments.
● Wait a full day after mounting casts before storing the articulator in a carrying
case or corrugated carton.
● Moisture dissipation from the stone in an enclosed area causes alkalinity of the
stone mixture which can damage the articulator surface

CONCLUSION
● The accurate articulation of the maxilla to an articulator is essential for achieving
optimal outcomes in prosthodontic treatment. The use of precise mounting
techniques, such as facebow transfer and interocclusal records, ensures that the
articulator mimics the patient's maxillomandibular relationship, enabling the
fabrication of prostheses that function harmoniously with the patient's natural
occlusion.
● Despite the availability of digital technologies, the facebow transfer technique
remains a cornerstone in prosthodontics, highlighting its continued relevance and
importance in modern dental practice.
● gothic arch tracing remains a valuable tool in prosthodontics, offering a non-invasive
and cost-effective, simple, reliable, and easy accessibility make it a valuable
technique for prosthodontists seeking comprehensive assessments of mandibular
movements and occlusal stability, ultimately contributing to improved patient
outcomes in prosthodontic treatment.
