INTRODUCTION

The WHIP MIX Series 4000 Articulator and “QUICKMOUNT” Face-Bow are designed to enable the user to

quickly and easily mount casts of a patient’s jaws on a mechanical likeness that will reproduce their natural

relationship and movements with an acceptable degree of accuracy. The simplicity and speed with which

the necessary registrations are obtained and transferred to the WHIP MIX 4000 Series Articulator enable the

operator to accomplish corrective and restorative dentistry with much greater precision than has ever before

been possible.

The WHIP MIX 4000 Series Articulator serves as an excellent auxiliary instrument for diagnostic and

patient-education purposes. Being an “ARCON” type instrument, the WHIP MIX 4000 Series Articulator is

ideal for the study of occlusion and the movements of the temporomandibular joint. With the condyle located on

the lower frame and the guidance on the upper frame (arcon design), WHIP MIX semi-adjustable articulators

have become the preferred choice of many teaching institutions. Advancing to a fully adjustable articulator

becomes a much easier process after having initial training on an arcon semi-adjustable articulator.

As with all mechanical devices, the degree of perfection of the finishesd product depends to a great

extent on the operator’s comprehension of the results desired and on a complete understanding of the

limitations of the instrument being used. The instructions that follow in this manual make no attempt to

teach concepts of occlusion and articulation. They simply outline a method to obtain a face-bow registration,

itemize the other registrations needed, and detail their in setting the articulator.

These instructions will deliver the minimum amount of guidance that is considered necessary and do

not exhaust the capabilities of the articulator. Therefore, it is suggested that the operator refresh

his/her knowledge by reviewing one or more of the several excellent texts on subject of articulator

usage (see bibliography).

The 4000 Series Articulator has the following features:

• Ergonomic design.

• Tracking Type of Condylar Guidance with Progressive Side Shift capability.

• A permanent intercondylar width of 110 mm, which is the industry standard for Semi-Adjustable

Articulators with a fixed setting.

• Fully open access from the lingual position for easy access during denture setup.

• Easy to operate Locking Mechanism, which provides the following actions: In the locked position

it provides a quick way to return to centric position and locks the articulator for added stability. In

the mid-range position the Locking Mechanism allows the condylar ball to move freely down the

track of the condylar guides during excursive movements.

5

• 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.

6

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, theoperator 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 themid-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 accidentallyoverextending 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 forgreater 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 thelocking mechanism back. After unlocking one side, the upper member can be moved medially toseparate it from the lower frame.

OBTAINING FACE-BOW REGISTRATION

Fig. 2

Fig. 1

Items needed for a Face-Bow Registration:

Face-bow including nasion relator andface-bow fork (bite fork)

Elastomeric registration material

Adhesive for elastomeric

Fig. 3

I. Preparing Face-BowClean and properly disinfect the plastic earpieces before each use. If replacing them, makesure that the hole on the flat side of each isabove the side arm and the plastic is seateduntil it touches the shoulder of the earbow arm(Fig. 2). Note the ability of the nasion relatorassembly to move left and right along the crossbar and the face-bow caliper design allowingthe side arms to move equal distances duringthe opening and closing motions.

Center the nasion relator assembly on the crossbar between the two centering indications.Loosen the #8604 thumb screws on the face-bow and the #8643 thumb screws on thetransfer assembly.

II. Preparing Face-Bow ForkElastomeric registration material may be usedas a bite registration medium for the bite fork.Make sure bite fork has been sterilized andapply sufficient registration material to the topsurface of the bite fork. Position the bite fork sothat the midline of the bite fork aligns with facialmidline and support the fork until the materialhas set (Fig. 3). The record should make ashallow registration of the maxillary cusp tips,and not perforate through the bite fork. Inspectregistration for tissue interferences and trimaway any that is found with a Bard-Parker Knife.

III. Positioning Face-Bow onthe Patient and SecuringRegistrationBefore attempting to place the face-bow ontothe bite fork, it is suggested that the operatorrehearse the procedure with the patient. Cautionthe patient that the plastic ear pieces in theauditory canal will greatly amplify noises duringthe procedure. Support bite fork using cottonrolls placed underneath. A finger cot placed overeach ear piece will help facilitate properdisinfection of the face-bow.

Fig. 5

Completed Face-Bow Registration

With the bite fork positioned in the patient’s mouth,start the toggle onto bite fork shaft while the patientholds the side arms close to the ears. Note: Makesure the horizontal cross bar is above the bitefork shaft (Fig. 4). Instruct the patient to place eachear piece into the external auditory meatus and holdin place with a firm forward pressure. Center the nosepiece on the patient’s nasion and exert firm pressureon the nose piece shaft while tightening the nasionthumbscrew. This action will help to firmly seat theear pieces into the external auditory meatus.

With the patient continuing to hold onto the face-bow,position the toggle assembly on the bite fork shaftand slide until it is near, but not touching the lips andtighten the thumb screw. To prevent torquing of theface-bow and discomfort to the patient, support thefork and the horizontal bar with one hand whiletightening. Next tighten the thumb screw on thevertical bar while supporting the face-bow, againtaking care not to tilt the face-bow.

IV. Removing Face-Bow from the PatientLoosen the nasion thumb screw and slide the nasion relator away from the patient’s nose. Loosen thethumb screws on the face-bow and have the patient pull the ear pieces out of their ears. The entire face-bow assembly is removed by advising the patient to pull the ear pieces out of their ears while helping toremove the bite fork from the mouth.

V. Obtaining Interocclusal RecordsNow is a convenient time to make the interocclusal records and set the condylar guidance of thearticulator. There are several materials available that may be used to make interocclusal records. Thematerial selected should complement the particular technique used. The following interocclusal recordsshould be utilized to relate the mandibular cast to the maxillary mounting and to program the condylarguidance of the articulator:

• Centric Relation and/or Maximum Intercuspation

• Right Lateral

• Left Lateral

• Protrusive (optional)

DIRECT MOUNTING THE MAXILLARY CASTON THE 4000 SERIES ARTICULATOR

Fig. 8

The Direct Face-Bow attached to the Model4640 Articulator.

I. Preparing the 4000 Series ArticulatorEnsure the mounting surface between the articulator and the mounting plate is free of any debris. Anydebris between these surfaces will affect the interchangeability accuracy of the instrument. Tighten theblack 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 lockingscrew. Place a clean mounting plate on the upper and lower frame. Center the plastic incisal guide tableso that the rounded end of the incisal guide pin rests in the center of the table, then raise the incisal guidepin 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 thumbscrews 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 thehole on the medial side of each plastic ear piece of the face-bow (Fig. 7). Make sure the brass-mountingpin fits securely into the hole and tighten the thumb screw knobs. Allow the anterior end of the upperframe of the articulator to rest on the horizontal cross bar of the face-bow. Note: Some clinicians liketo press the face-bow arms against one’s body while tightening the thumb screw knobs. Makesure 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 groovesinto the base of the cast and soak the castbefore mounting. Seat the maxillary cast in theface-bow fork registration made previously andmake sure it is stable with no rocking. Someclinicians prefer to use some type of deviceplaced around the cast and bite fork forincreased stability. A face-bow fork support may

10

Fig. 9

be used to support the bite fork during the mountingof the maxillary cast. The face-bow fork supportattaches to the lower frame in place of the lowermounting plate. The cross arms can be raised tocontact the under-surface of the face-bow fork toprevent flexing or movement of the fork (Fig. 9). Placemounting stone on the base of the cast and mountingplate. An inaccurate mounting will result if the bitefork flexes during mounting.

Close the upper frame to contact the cross bar,bringing the mounting stone on the two surfacestogether. 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 stonemay be used to fill in any voids left from the first mounting. Take care to avoid smearing excess mountingstone on the articulator parts.

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 unscrewthe locking screw on the cross bar holding thevertical rod. This releases the transfer assemblywhich holds the face-bow fork (Fig. 11). Attach the#8686 Support Bar to the top of the Vertical Rod andsecure in place with the same locking screw (Fig. 12).With the #4611 Support Rod attached to the uppermember, rotate the upper frame of the articulatoruntil it is resting on the tabletop. This will make iteasier 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 ArticulatorInsert the vertical rod of the transfer assembly intothe transfer base assembly and lower it until thebottom of the vertical rod contacts the transfer base.Tighten the Clamp Screw so that the vertical rod fitssecurely in the transfer base (Fig. 13). Remove theincisal guide pin from the upper member. Place theupper frame of the articulator onto the lower frame sothe front of the upper frame now rests on the supportbar. Rotate the Locking Mechanism until the lever isin the “up” position. This locks the condyles againstthe 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.)

12

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, whichcompletely encircles the pin. The pin should then be adjusted 3–5 mm above the zero mark to compensatefor 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 sideshift 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 iscompletely seated – no rocking should occur (Fig. 14). If you haven’t done so, cut retention grooves intothe base of the lower cast and properly wet it prior to mounting. Position the mandibular cast on the CRor 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 andthe lower mounting plate. Hinge the lower frame closed until the incisal guide pin meets the incisal guideblock (Fig. 15). Make sure the condylar elements are seated flush against the posterior and superior wallsof the condylar guides. Carefully hold the articulator in this position until the mounting stone has set. Asecond mix of mounting stone may be used to fill in any voids left from the first mounting to produce apleasing aesthetic result.

Finally, loosen the incisal guide pin screw and makesure the upper and lower casts contact. Retightenthe incisal guide pin screw and make sure the incisalguide pin is positioned in the center of the incisalguide 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 tomove freely down the tracking surface of the fossa element. Loosen both condylar guides and set them tothe 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 sideshift guides to their most open position (Fig. 19). Loosen the incisal guide pin screw and raise theincisal guide pin to prevent any interference. Retighten the incisal guide pin screw. Carefully seat the leftlateral excursion interocclusal record on the upper cast. It may be easier to perform this procedure withthe articulator inverted. While lightly holding the articulator together, make sure that the left condyle isseated “flush” against the rear wall. Gently seat the lower cast into the left lateral record and lightly holdthe articulator and casts in position. Note: The teeth of the cast should seat evenly into the leftlateral record. If the posterior teeth are raised out of the record the condylar inclination needs to bedecreased 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 theguide until the teeth of the upper cast seat evenlyin the left lateral record. It is advisable whenmaking these adjustments that the contact shouldalso be judged by sight, rather than dependingsolely on the sense of touch. This helps ensure thatthe casts are not forced out of position. Tighten thecondylar guide locking knob to clamp the guide inposition. DO NOT USE EXCESSIVE PRESSUREwhen tightening the locking knob.

14

Fig. 20

To set the right progressive side shift, loosen the rightside shift holding screw and move the rightside shift guide until it touches the side of thecondyle element (Fig. 20). Retighten the right sideshift guide locking screw. Record the amount ofcondylar inclination and progressive side shift foundon the left side on a patient registration card. Afterthe right condylar guidance has been recorded,the condylar guidance should be neutralized aspreviously described. The left condylar guidance isadjusted using the right lateral excursion recordand repeating steps listed above.

15

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 themaxillary cast and gently seat the mandibular cast into the protrusive record. It may easier to perform thisprocedure with the upper frame and its cast inverted. Both condylar elements will have moved away fromthe 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 tightenthe condylar locking knob. Record the reading and repeat the procedure on the right side. Note: Thelateral 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 apermanent record of a specific case, the natural incisal guidance may be recorded. Fabrication of a customincisal guide is accomplished by adding a layer of self-curing resin to the Plastic Incisal Guide Block or theDovetail Incisal Guide Block. Raise the incisal guide pin 1–2 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 tosimulate a straight protrusive movement (end to end) (Fig. 21). From centric, move the upper member ofthe articulator to give a straight right lateral movement. Then, move the upper member of the articulator togive a straight left lateral movement. Move through all intermediate excursions between the lateral andprotrusive positions (Fig. 22). Allow the acrylic to harden and trim off excess acrylic.

16

I. Constructing Occlusion RimsContour the upper and lower occlusion rims, establish occlusal vertical dimension, apply the customarymarkings to the wax rims and establish a centric jaw relation record. Create wedge-shaped V indices in theocclusion rims.

II. Preparing the Face-Bow ForkSome clinicians prefer to utilize a pronged bite forksuch as the #8631 Offset Bite Fork (Fig. 24). Cleanand properly disinfect the plastic ear pieces beforeeach use. Center the nasion relator assembly onthe cross bar. Loosen the #8604 thumb screws onthe face-bow and the #8643 thumb screws on thetransfer 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 theface-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 elastomericregistration material or other appropriate recordmedium is placed onto the V indices of the wax rim(Fig. 25). The patient is guided into centric relationand is allowed to close until the wax rims come intocontact. The registration material is allowed to setand is then removed.

VI. Preparing the Articulator for Mounting Casts

Many operators prefer to replace the plastic incisalblock with an adjustable metal table, such as the

#2460 Adjustable Incisal Guide Table (Fig. 26). Remove the plastic incisal guide block from the articulatorand 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 incisalguide pin lies directly over the scribed line on the guide table (Fig. 27). Note: Guide pin must be setat “0” on the upper member.

VII. Mounting the Maxillary CastFollow the same procedures as described earlier, Direct Mounting the Maxillary Cast on the 4000 SeriesArticulator, 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 andapply mounting stone. Additional jaw relation records can verify accuracy. Accurate fit of the verificationrecords into the V-shaped indices will denote a precise mounting.

IX. Setting the Adjustable Incisal Guide TableAfter the anterior denture teeth are positioned, theadjustable guide table may be set.

Release the locking mechanisms on the articulator.Loosen the #2472 Indicator Clamp Knob of theadjustable incisal guide table and bring the anteriorteeth into edge-to-edge contact. Adjust the inclinationof the guide table until it contacts the incisal pin thenretighten the thumb screw (Fig. 28). Move the teethin a left lateral relation and set the right wing of thetable. Repeat this same operation for the left wingin 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 toallow 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 theQuickMount Remount Jig on the lower frame(Fig. 29). Add sufficient stone to the remountjig to form an index of the cusp tips of thedenture teeth.

XII. Remounting CastsAfter polishing, the maxillary denture can be mountedto the articulator for a clinical remount to evaluatethe denture occlusion. Using the remount index,mount the maxillary denture and remount cast tothe articulator (Fig. 30). Using new centric relationrecords, mount the mandibular denture and remountcast. The denture occlusion may be evaluated andadjusted as needed.

INTERCHANGEABILITY WITH THE4000 SERIES ARTICULATOR

All 4000 Series Articulators feature the “ACCUMOUNT” Mounting System. The “ACCUMOUNT” Systemmakes it possible for the dental practitioner and the dental laboratory to interchange casts withoutexchanging 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. Thisassures that casts can be interchanged between any 4000 Series Articulator without loss of accuracy.

Features and Advantages1. 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

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 record

showing 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

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 articulator’s ability to

accurately reproduce a patient’s 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.
