Capability of removing the upper member for greater access for cleaning and servicing the

articulator. To remove the upper member, simply push the spring-loaded release button located

on the side of the condylar element and move the locking mechanism back to release the

condylar ball.

A Support Pin to support the upper frame of the articulator when open.

A built-in storage compartment for storing the Support Pin when not being used.

Ergonomically designed Condyle Locking Knobs for greater ease in locking the condyle in

the desired position.

Screw type mounting plates standard, but can be upgraded to include the QuickMount

Magnet System.

Innovative ACCUMOUNT Mounting System of interchangeability. This will make it possible to

interchange mounted casts between any 4000 Series Articulator as found in the 2000 and

3000 Series Articulators.

The main difference between the 4000 Series Articulator and traditional WHIP MIX Articulators is the

elimination of the crossbar between the uprights on the lower member. The Locking Mechanism is

used as the primary source for securing the articulator in place.

OPERATION INSTRUCTIONS FOR THE LOCKING MECHANISM

a. When the tabs are in the UP position, the condyles are locked in centric. In this locked position, the

operator is assured that the articulator is locked in centric and ensures the stability of the articulator.

b. Moving the tabs back one position places the Locking Mechanism in the mid-range position. In the

mid-range position the condyles can be moved down the tracking surface of the fossa element duringexcursive movements. The design of the Locking Mechanism prevents the user from accidentally

overextending the lateral movements, which could destroy work in progress.

The upper member of the articulator can be easily removed from the lower member if necessary for

greater access during cleaning and servicing of the articulator. To accomplish this, push the spring-

loaded release button located on the outside of the fossa element while simultaneously rotating the

locking mechanism back. After unlocking one side, the upper member can be moved medially to

separate it from the lower frame.

Fig. 1

Items needed for a Face-Bow Registration:

Face-bow including nasion relator and

face-bow fork (bite fork)

Elastomeric registration material

Adhesive for elastomeric

Fig. 3

I. Preparing Face-BowClean and properly disinfect the plastic ear

pieces before each use. If replacing them, make

sure that the hole on the flat side of each isabove the side arm and the plastic is seated

until it touches the shoulder of the earbow arm

(Fig. 2). Note the ability of the nasion relator

assembly to move left and right along the cross

bar and the face-bow caliper design allowing

the side arms to move equal distances during

the opening and closing motions.

Center the nasion relator assembly on the cross

bar between the two centering indications.

Loosen the #8604 thumb screws on the face-

bow and the #8643 thumb screws on the

transfer assembly.

II. Preparing Face-Bow ForkElastomeric registration material may be used

as a bite registration medium for the bite fork.

Make sure bite fork has been sterilized andapply sufficient registration material to the top

surface of the bite fork. Position the bite fork so

that the midline of the bite fork aligns with facial

midline and support the fork until the material

has set (Fig. 3). The record should make a

shallow registration of the maxillary cusp tips,

and not perforate through the bite fork. Inspect

registration for tissue interferences and trim

away any that is found with a Bard-Parker Knife.

III. Positioning Face-Bow onthe Patient and SecuringRegistrationBefore attempting to place the face-bow onto

the bite fork, it is suggested that the operator

rehearse the procedure with the patient. Caution

the patient that the plastic ear pieces in the

auditory canal will greatly amplify noises duringthe procedure. Support bite fork using cotton

rolls placed underneath. A finger cot placed over

each ear piece will help facilitate proper

disinfection of the face-bow.

DIRECT MOUNTING THE MAXILLARY CASTON THE 4000 SERIES ARTICULATOR

Fig. 8

The Direct Face-Bow attached to the Model

4640 Articulator.

I. Preparing the 4000 Series ArticulatorEnsure the mounting surface between the articulator and the mounting plate is free of any debris. Any

debris between these surfaces will affect the interchangeability accuracy of the instrument. Tighten the

black condylar locking knob while pressing the condylar guide assembly medially against the upper frameof the articulator. Set each progressive side shift setting to the 0 mark and tighten the side shift locking

screw. Place a clean mounting plate on the upper and lower frame. Center the plastic incisal guide table

so that the rounded end of the incisal guide pin rests in the center of the table, then raise the incisal guide

pin so that the upper member of the articulator is able to rest on the horizontal crossbar of the face-bow.

Attach the #4611 Support Bar to the upper member.

II. Placing the Direct Mounting Face-Bow Using the Metal Face-BowSlide the Nasion Relator Assembly over until it contacts the left earbow half (Fig. 6). Loosen the thumb

screws on top of the face-bow. While holding the face-bow in one hand and the articulator in the other,

position the brass mounting pin, located on the outer edge of the upright post on the lower frame, into the

hole on the medial side of each plastic ear piece of the face-bow (Fig. 7). Make sure the brass-mounting

pin fits securely into the hole and tighten the thumb screw knobs. Allow the anterior end of the upper

frame of the articulator to rest on the horizontal cross bar of the face-bow. Note: Some clinicians like

to press the face-bow arms against ones body while tightening the thumb screw knobs. Make

sure the articulator with attached face-bow is stable. Bring the locking mechanism tabs to the up

position to lock the articulator in position and to provide added stability.

III. Mounting the MaxillaryCast with a Direct MountingFace-BowPrepare the cast by placing retention grooves

into the base of the cast and soak the cast

before mounting. Seat the maxillary cast in the

face-bow fork registration made previously andmake sure it is stable with no rocking. Some

clinicians prefer to use some type of device

placed around the cast and bite fork for

increased stability. A face-bow fork support may


10/36

10

Fig. 9

be used to support the bite fork during the mounting

of the maxillary cast. The face-bow fork support

attaches to the lower frame in place of the lower

mounting plate. The cross arms can be raised to

contact the under-surface of the face-bow fork to

prevent flexing or movement of the fork (Fig. 9). Place

mounting stone on the base of the cast and mounting

plate. An inaccurate mounting will result if the bite

fork flexes during mounting.

Close the upper frame to contact the cross bar,

bringing the mounting stone on the two surfaces

together. Do not use too thick of a mix of mounting

stone or attempt to apply force when the stone has already begun to set. Keep the upper frame in thisclosed position until the mounting stone has set. If a device was used to secure the cast to the bite fork,

carefully remove it and then remove the face-bow from the articulator. A second mix of mounting stone

may be used to fill in any voids left from the first mounting. Take care to avoid smearing excess mounting

stone on the articulator parts.

Fig. 13

MOUNTING THE MAXILLARY CAST USINGTHE INDIRECT MOUNTING METHOD

I. Preparing the Face-Bow and Articulator for Mounting CastsObtain the face-bow registration in the usual manner.

Remove the face-bow from the patient and unscrew

the locking screw on the cross bar holding thevertical rod. This releases the transfer assembly

which holds the face-bow fork (Fig. 11). Attach the

#8686 Support Bar to the top of the Vertical Rod and

secure in place with the same locking screw (Fig. 12).

With the #4611 Support Rod attached to the upper

member, rotate the upper frame of the articulator

until it is resting on the tabletop. This will make it

easier to install the transfer base assembly. The

#9176Q QuickMount Transfer Base Assembly is usedfor demonstration in this manual. If present, remove

the mounting plate from the lower frame and install the #9176Q QuickMount Transfer Base Assembly.

II. Placing the Face-Bow Transfer Assembly on the Articulator

Insert the vertical rod of the transfer assembly into

the transfer base assembly and lower it until the

bottom of the vertical rod contacts the transfer base.

Tighten the Clamp Screw so that the vertical rod fits

securely in the transfer base (Fig. 13). Remove the

incisal guide pin from the upper member. Place the

upper frame of the articulator onto the lower frame so

the front of the upper frame now rests on the support

bar. Rotate the Locking Mechanism until the lever is

in the up position. This locks the condyles against

the posterior and superior walls of the fossa element.

III. Mounting the Maxillary Cast(Refer to Direct Mounting the Maxillary Cast on the 4000 Series Articulator on page 9, part III.)

Fig. 14 Fig. 15

Fig. 16

MOUNTING THE MANDIBULAR CAST

I. Preparing the ArticulatorThe upper and lower frames are made parallel by aligning the top of the pin boss with the dark line, which

completely encircles the pin. The pin should then be adjusted 35 mm above the zero mark to compensate

for the thickness of the Centric Relation (CR) or Maximum Intercuspation (MI) registration used to mountthe lower cast. Make sure the Locking Mechanism tabs are in the up position. Set both progressive side

shift guides to the 0 position.

Place the articulator upside down. This positions the mounted cast with its occlusal surfaces upward.

Place an interocclusal CR or MI registration record on the maxillary cast, making sure the record is

completely seated no rocking should occur (Fig. 14). If you havent done so, cut retention grooves into

the base of the lower cast and properly wet it prior to mounting. Position the mandibular cast on the CR

or MI registration and check for stability.

For added stability, some clinicians use an alternate source to hold the upper and lower casts together.

Hinge the lower frame into the open position and apply mounting stone to the base of the lower cast and

the lower mounting plate. Hinge the lower frame closed until the incisal guide pin meets the incisal guide

block (Fig. 15). Make sure the condylar elements are seated flush against the posterior and superior walls

of the condylar guides. Carefully hold the articulator in this position until the mounting stone has set. A

second mix of mounting stone may be used to fill in any voids left from the first mounting to produce a

pleasing aesthetic result.

Finally, loosen the incisal guide pin screw and make

sure the upper and lower casts contact. Retighten

the incisal guide pin screw and make sure the incisal

guide pin is positioned in the center of the incisal

guide block (Fig. 16).

Fig. 19

SETTING THE CONDYLAR GUIDANCE OFTHE MODEL 4640 AND 4641 ARTICULATORS

After removing the CR or MI registration, release the centric lock by moving the tabs on the Multi-

Functional Spring Mechanism to the mid-range position (Fig. 17). This allows the condyle mechanism to

move freely down the tracking surface of the fossa element. Loosen both condylar guides and set them to

the 0

setting indicated on the condylar inclination scale (Fig. 18). Firmly tighten the left condylar guidelocking knob and lightly secure the right condylar guide locking knob. Note: Set the progressive side

shift guides to their most open position (Fig. 19). Loosen the incisal guide pin screw and raise the

incisal guide pin to prevent any interference. Retighten the incisal guide pin screw. Carefully seat the left

lateral excursion interocclusal record on the upper cast. It may be easier to perform this procedure with

the articulator inverted. While lightly holding the articulator together, make sure that the left condyle is

seated flush against the rear wall. Gently seat the lower cast into the left lateral record and lightly hold

the articulator and casts in position. Note: The teeth of the cast should seat evenly into the left

lateral record. If the posterior teeth are raised out of the record the condylar inclination needs to be

decreased until the teeth are seated evenly in the record.

To set the inclination of the right condylar guide,

carefully loosen the locking knob and rotate the

guide until the teeth of the upper cast seat evenly

in the left lateral record. It is advisable when

making these adjustments that the contact should

also be judged by sight, rather than depending

solely on the sense of touch. This helps ensure that

the casts are not forced out of position. Tighten the

condylar guide locking knob to clamp the guide in

position. DO NOT USE EXCESSIVE PRESSURE

when tightening the locking knob.

SETTING THE CONDYLAR INCLINATIONUSING A PROTRUSIVE RECORD

Fig. 21 Fig. 22

Fig. 23

Custom Incisal Guide Table

Neutralize the condylar inclination and progressive side shift settings. Place the protrusive record on the

maxillary cast and gently seat the mandibular cast into the protrusive record. It may easier to perform this

procedure with the upper frame and its cast inverted. Both condylar elements will have moved away from

the posterior surfaces of their respective condylar guides. Using sight and touch, rotate the left condylarguide until the teeth on the left side of the upper cast seat evenly into the protrusive record, then tighten

the condylar locking knob. Record the reading and repeat the procedure on the right side. Note: The

lateral records are used to determine the progressive side shift settings.

I. Fabricating a Custom Incisal Guide TableTo prevent possible wearing away of the stone casts during manipulation of the articulator, or to make a

permanent record of a specific case, the natural incisal guidance may be recorded. Fabrication of a custom

incisal guide is accomplished by adding a layer of self-curing resin to the Plastic Incisal Guide Block or the

Dovetail Incisal Guide Block. Raise the incisal guide pin 12 mm for fabricating the custom incisal guide.Mix enough acrylic to place approximately 1/4" on top of the incisal guide block.

Carefully close the articulator in centric position and move the upper frame of the articulator back to

simulate a straight protrusive movement (end to end) (Fig. 21). From centric, move the upper member of

the articulator to give a straight right lateral movement. Then, move the upper member of the articulator to

give a straight left lateral movement. Move through all intermediate excursions between the lateral and

protrusive positions (Fig. 22). Allow the acrylic to harden and trim off excess acrylic.

I. Constructing Occlusion RimsContour the upper and lower occlusion rims, establish occlusal vertical dimension, apply the customary

markings to the wax rims and establish a centric jaw relation record. Create wedge-shaped V indices in the

occlusion rims.

II. Preparing the Face-Bow ForkSome clinicians prefer to utilize a pronged bite fork

such as the #8631 Offset Bite Fork (Fig. 24). Clean

and properly disinfect the plastic ear pieces before

each use. Center the nasion relator assembly on

the cross bar. Loosen the #8604 thumb screws on

the face-bow and the #8643 thumb screws on the

transfer assembly.

III. Preparing Face-BowArmamentarium

Follow the procedures found on page 7.

IV. Positioning the Face-BowMake sure the midline of the palate and the stem of the bite fork is properly aligned. Position the

face-bow onto the patient as described earlier on page 7. Once the face-bow record has been made,remove the wax rim and record base from the bite fork registration.

V. Obtaining Interocclusal RecordsTo make jaw relation records, an elastomeric

registration material or other appropriate record

medium is placed onto the V indices of the wax rim

(Fig. 25). The patient is guided into centric relation

and is allowed to close until the wax rims come into

contact. The registration material is allowed to setand is then removed.

VI. Preparing the Articulatorfor Mounting Casts

Many operators prefer to replace the plastic incisal

block with an adjustable metal table, such as the

#2460 Adjustable Incisal Guide Table (Fig. 26). Remove the plastic incisal guide block from the articulator

and install the adjustable incisal guide table. With the chiseled end pointed down, set the pin to the 0

mark, and adjust the position of the adjustable incisal guide table until the chiseled end of the incisal

guide pin lies directly over the scribed line on the guide table (Fig. 27). Note: Guide pin must be set

at 0 on the upper member.

VII. Mounting the Maxillary CastFollow the same procedures as described earlier, Direct Mounting the Maxillary Cast on the 4000 Series

Articulator, Mounting the Maxillary Cast using the Indirect Mounting Method.

VIII. Mounting the Mandibular CastPlace the jaw relation record between the wax occlusion rims. Invert the articulator with casts attached and

apply mounting stone. Additional jaw relation records can verify accuracy. Accurate fit of the verification

records into the V-shaped indices will denote a precise mounting.

IX. Setting the Adjustable Incisal Guide Table

After the anterior denture teeth are positioned, the

adjustable guide table may be set.

Release the locking mechanisms on the articulator.

Loosen the #2472 Indicator Clamp Knob of the

adjustable incisal guide table and bring the anterior

teeth into edge-to-edge contact. Adjust the inclination

of the guide table until it contacts the incisal pin thenretighten the thumb screw (Fig. 28). Move the teeth

in a left lateral relation and set the right wing of the

table. Repeat this same operation for the left wing

in a right lateral position.

X. Obtaining Protrusive RecordThe aesthetic try-in appointment affords the clinician the ability to verify tooth setup and obtain a well-

indexed protrusive record. The protrusive record should be created at an extended protrusive position to

allow for bilateral condylar movement. Set condylar inclination on the articulator as described previously.

XI. Fabricating a Remount IndexAfter denture processing, replace the mounting,

cast, and denture onto the articulator. Attach the

QuickMount Remount Jig on the lower frame(Fig. 29). Add sufficient stone to the remount

jig to form an index of the cusp tips of the

denture teeth.

XII. Remounting CastsAfter polishing, the maxillary denture can be mounted

to the articulator for a clinical remount to evaluate

the denture occlusion. Using the remount index,

mount the maxillary denture and remount cast to

the articulator (Fig. 30). Using new centric relation

records, mount the mandibular denture and remount

cast. The denture occlusion may be evaluated and

adjusted as needed.

INTERCHANGEABILITY WITH THE4000 SERIES ARTICULATOR

All 4000 Series Articulators feature the ACCUMOUNT Mounting System. The ACCUMOUNT System

makes it possible for the dental practitioner and the dental laboratory to interchange casts without

exchanging articulators.

During manufacture, each 4000 Series Articulator has a special table firmly and precisely attached to thelower frame using a special fixture and low-fusing alloy.

The relationship between the upper and lower mounting plate is checked to verify precise alignment. This

assures that casts can be interchanged between any 4000 Series Articulator without loss of accuracy.

Features and Advantages

1. When clinicians and dental students use a dental laboratory that has a Series 4000 Articulator,

casts need no longer be mounted on an articulator when shipped to such laboratory.

2. Clinicians can purchase fewer instruments while maintaining the same level of care for

their patients.

3. Instrument damage and lost parts caused by shipping the articulator to and from the dental

laboratory is eliminated.

4. Precise alignment of the upper and lower frames is checked at the factory prior to shipping.


21/36

1. When securing interocclusal records to be used in mounting casts and setting the articulator,

never allow the teeth to penetrate the recording material (impression compound, wax, gypsum,

impression paste, etc.) too deeply. They should never contact the opposing teeth, the metal

face-bow fork or any firm material that may be used as a carrying tray or handle. Any recordshowing evidence of penetration should be discarded and remade.

2. The more stable a recording material is, the more it will resist distortion during its later use.

Any such material should be in a very soft state, however, during the initial recording procedure.

3. The following technique may be used to secure interocclusal records of partially

endentulous patients.

If natural dentition opposes the edentulous space, the partial occlusion rim is built up to nearly

touch the opposing teeth. Zinc oxide and eugenol impression paste is then added to the surface

of the occlusion rim of sufficient depth to register the tips of the opposing teeth when brought

into the desired relationship.

When the opposing spaces are both endentulous, one occlusion rim is built up in the customary

manner to near the occlusal plane, while the opposing rim is built to near this plane with small

cones of hard wax (or plastic) to indicate the registration in the impression paste.

When absence of teeth makes it necessary to obtain interocclusal records on partial occlusion

rims, these records must be made with the supporting soft tissue in as near a static condition

as is possible; some combination of these ideas can be planned to accomplish this with

acceptable accuracy.

4. With casts of unusually thin vertical dimensions, which would necessitate the use of a great bulk

of mounting stone, it is suggested that the mounting plate be built up to near the correct thickness

with a mix of mounting stone. This mix should be allowed to set for twenty minutes or longer before

the actual mounting procedure is performed. This will minimize any effect of the gypsum setting

expansion on the mounting accuracy.

5. It is suggested that a split cast mounting be made on the articulator before mounting the first case.

This will be used for reference purposes should the articulator ever be dropped or mishandled.

If the split cast mounting ever shows any discrepancy, return the articulator to the dealer for

factory recalibration at a nominal charge.

REMINDERS AND SUGGESTIONS


22/36

22

The Whip Mix Model 4640 Articulator is a sturdily constructed instrument that will provide many

years of service with reasonable care. Both the upper and lower frames are made of cast aluminum.

All aluminum parts are anodized to prevent corrosion or staining. Each condyle element consists of a

stainless steel shaft and durable plastic condyle ball. The condylar guide assemblies are made of

anodized aluminum.

Do not attempt to dislodge or remove the condyle ball from the condyle element shaft.

The sealing compound placed over the #8548 Set Screws should not be disturbed.

Do not attempt to remove the #2428 Screws holding each condyle release mechanism.

Avoid getting wax or stone in the screw holes which may damage threads.

Tighten screws snugly, but not too tightly. Overtightening the retaining screws can strip

the threads.

It is a good idea to use a carrying case when the articulator is transported. Dropping the

articulator may result in bent or broken parts which may affect the articulators ability to

accurately reproduce a patients mandibular movements.

A thin film of lubricant (Whip Mix LUBRIPLATE) or silicone spray applied to the surface upon

which the condylar elements move will provide a smooth action of these parts.

Failing to remove excess stone, or not keeping the articulator clean, may result in corrosion

of the articulator surfaces.

Apply silicone spray to articulator frame to prevent plaster or stone from sticking to surfaces.

If you notice any bent parts on the articulator, have it serviced immediately to ensure it

maintains its interchangeability.
