Prosthodontics has changed significantly over the years to the point where patient’s acceptance orrequests for complete removable dentures has been replaced with requests to save the natural dentitionwith restorative and fixed prostheses, including implants. The relationship of teeth, TM Joints andneuromuscular system is being increasingly recognized as important factors in fixed prosthodontics aswell as orthodontics. Concurrently, the need for user-friendly articulators that simulate individual patient’scharacteristic jaw movements has increased.

Using a point midway between the lateral and medial condyle pole to represent the path of the condyle,research shows that the condylar movements of one patient are similar in certain aspects to those ofothers. For example, beyond the lateral functional range (3mm from centric relation) contralateral condyles,in the horizontal plane, show similar orbiting paths of about 6-7°. The curvature of protrusive and lateralborder paths in the functional range, in the sagittal plane, are approximately ¾” radii. The lateral borderand protrusive paths of contralateral condyles, in the sagittal plane, are usually identical in the functionalrange (3mm). The paths of ipsilateral condyles are primarily horizontal and/or pivotal in the functionalrange (3mm).

In the lateral functional range (3mm), condylar movement patterns differ primarily in two aspects: (1) theradius curvature of the lateral border path of the contralateral condyle in the horizontal plane and (2) thesteepness of the lateral border and protrusive path in the sagittal plane.

Research shows that under functional loads, patients’ condylar movements on the contralateral side arenot straight paths. The paths curve simultaneously in the three planes of space. Jaw movement studiesalso show that contralateral condylar paths create the major differences between patients’ lateral jawmovements in the functional range (3mm). The ipsilateral condylar paths (Bennett) are primarily horizontaland/or pivotal in the functional range (3mm).

Over the years, attempts have been made to compensate for the curved contralateral paths observedand recorded on patients by various methods. Some manufacturers have incorporated a variablestraight-line “side shift” in their articulator guides (Fig. b). The contralateral condylar element, (Fig. b),does not begin its detrusive movement until after the "side shift" has ended at point “S”. Thus a purehorizontal movement takes place on the articulator. In some instances these horizontal articulatormovements encompass almost the entire occlusal width of the posterior teeth. Negative effects ofhorizontal straight line overcompensating “side shift” articulator movements (Fig. b) include:

(1) Articulators that become awkward to manipulate(2) Unnatural mandibular motion simulation(3) Possibilities of producing low profile (flattened) occlusal surfaces which may overload patients’

temporomandibular joints, teeth, muscles, periodontia, ridges, implants, and prostheses duringfunction.

Compensating curved contralateral articulator paths (Fig. c ) are superior because:(1) Research shows the articulator movements more closely simulate those of the individual patient.(2) They enable dentists, technicians, and students to observe realistic movements of the mandible

as it translates and rotates simultaneously in three planes of space (six degrees of freedom ofmotion).

(3) The articulators are easier to manipulate (user-friendly) during diagnosis as well as constructingartificial occlusal surfaces.

(4) Curved paths help dentists and technicians create better occlusal forms while concurrently

Introduction to the Panadent System

A functional border path of the contralateral condylar element is represented by the dottedcurved lines in (Figs. a and b), and the solid curved line (Fig. c). The path from CR to B (Fig. a)represents an undercompensating straight line contralateral guide. The solid rectilinear lineCR-S-B (Fig. b) represents an over-compensating straight line, pure horizontal “immediateside shift” guide. (Fig. c) represents the compensating curved path guide. The letter P in eachof the three types represents protrusive movement. The letter W represents ipsilateral movement(Bennett) which is primarily horizontal in the functional range (3mm).

The major disadvantage of “straight line” undercompensating articulators is that most patients’condylar movements under functional load (dotted line) exceed the border limits of the straightpath guides CR-B (Fig. a). This undercompensation creates potential posterior occlusalinterferences of a prosthesis when placed under functional loads in the mouth.

PANADENT PREFORMED CONDYLAR AXIS MOTION ANALOGS

The Panadent Articulator System is the direct result of the most advanced research inmandibular motion simulation (see Bibliography). It is based upon information gathered fromhundreds of patients’ transverse (horizontal) condylar axis motion analogs. The end result isa scientific rationale for uncomplicated, high fidelity, user-friendly, instrumentation for simulatingindividuals characteristic jaw movements.

A series of statistically selected three-dimensional analogs of condylar axis motions arepreformed in resin. They include the curved, protrusive and curved lateral border pathways.The series of analogs come in five sizes, each with increasing curvatures of contralateralcondylar Bennett movement: 0.5, 1.0, 1.5, 2.0, 2.5mm, for right and left sides. The halfmillimeter increments are measured at a point 3mm forward in the sagittal plane from centricrelation position where a vertical line intersects the condylar pathway. The motion analogscan be rotated individually in the sagittal plane to match the protrusive and lateral borderpathways recorded on the patient.



3

The analogs can also be selected so that the right and left sides have different sized curvaturesof contralateral condylar movement. Since patients' condylar paths are primarily horizontaland/or pivotal, in nature, the Panadent preformed motion analogs are produced with horizontal(transtrusive) paths on the ipsilateral side.

The Panadent analog articulator is a precision instrument designed to meet the needs ofstudents of occlusion as well as dentists in advanced clinical practice. The Basic ArticulatorModule includes one pair of motion analogs. Based on research, the 1.5mm analogs fit thelargest percent of the population (90%, see Fig. f).

Fig. dSchematic illustration of Panadent preformedIntercondylar Axis Motion Analogs. Note thevariations in the curved contralateral paths in thefunctional range of 3.0mm from centric relation(CR) in the horizontal plane. The curve pathwayin the vertical plane averages ¾”R. The orbitingpaths beyond the 3.0mm point are caused bythe generally pivoting ipsilateral condyle whenthe mandible is forced into extreme movements.These orbiting paths are of no clinical significancein lateral function. The frontal plane paths arenot shown (to avoid line confusion) but are similarto the horizontal (transverse) planecharacteristics.

The right and leftanalogs may be used in any combination to allowfor differences between the right and left side ofthe patient. The analogs may be rotatedindividually to duplicate the patients condylar axispath.

PANA-MOUNT ™ FACE-BOW:

The Pana-mount Bow has been designed and engineered to be, strong, fast, easy to use,face-bow and comfortable for the patient.

The bow can be used as an ear-bow for average-axis mounting, but also has provisions foradding adjustable axis arms for true hinge-axis mounting. It also has a detachable indexedbite-fork assembly and mounting fixture which eliminates the need for attaching the face-bowdirectly to the articulator. By having extra bite-fork assemblies, the bow can be used immediatelyfor other patients and the casts may be mounted at a later time.

PANADENT JAW POSITION INTEROCCLUSAL RECORD SYSTEM

It has long been recognized that wax “check-bite” records have many shortcomings and areunreliable in clinical practice. This manual presents a non-wax method for making accuratecentric relation and protrusive inter-occlusal records for mounting patients’ casts and adjustingthe articulator.

The Panadent Interocclusal Record System is based on the Lee method. It uses a preformedsoft metal tray (Bite-Tray™) for conveying Bite Registration material to the teeth as well as acompound (modeling compound) lower anterior tooth position index. Softened compoundallows the operator to index the lower anterior teeth in either a retruded (CR) or a protrudedposition. When hardened the compound index enables the patient to repeat and hold thedesired mandibular position while the interocclusal registration material is hardening.

The following procedure is followed whenPanadent Bite-Tab compound discs are usedfor bite-fork registration.

Bend backing-sheet sharply at extreme printedend of Bite-Tab strip to free end of strip so it canbe grasped with index finger and thumb. PeelBite-Tab strip away from backing sheet. Do nottouch adhesive under end of tab wherecompound is located.

Press one Bite-Tab at each of the following sixlocations: left molar, right molar, and incisor onupper and lower surfaces (six tabs) on clean,dry bite-fork.

Hold Bite-Tab with thumb and index finger atlateral edges (arrows). Fold printed end of tabback (adhesive to adhesive) at dotted line. Thisfold-back produces a non-stick flap for easyremoval of Tab after maxillary cast has beenmounted. Do not touch adhesive under Bite-Tabsince powder from latex gloves will preventBite-Tab from adhering to bite-fork.

Place intra oral end of bite-fork in hot water (125°F/ 40°C) for about one half to one minute to softenBite-Tab compound discs. If tap water is not hotenough, hot coffee or coffee water will work wellto soften compound.

ATTENTION: Do not place bite-fork in regularwater-bath since wax residues andoils in water-bath will preventBite-Tabs from adhering to bite-fork.

Remove Panadent Bite-Trays from package.

Although Bite-Trays have been manufactured ina sanitary manner, trays should be sterilized priorto patient use. Sterilization of Bite-Trays may beby autoclave, chemclave or cold sterilizingsolution.

Paint Bite-Tray to be used with fast dryingimpression adhesive (e.g., Impergum) on bothsides in perforated areas only.

If maxillary cast of patient's teeth is available,place cast on Bite-Tray with incisors against up-turned anterior flange. Cut off extending portionof tray distal to second molars. Tray should coverfirst and second molars and distal extensionedentulous areas. Third molars should only beincluded if they are to be needed as bridgeabutments etc.

The first phase of maxillary registration is thesame (generic) as all types of interocclusalrecords (e.g., centric relation, protrusive as wellas lateral border).

Hold Bite-Tray with thumb and index finger atserrated areas on lateral edges of tray for placingtray in patient's mouth (arrows).

Remove any sharp edges of Bite-Tray withsandpaper disc, round stone, or abrasive rubberwheel.

Center tray laterally against patient’s maxillaryteeth with anterior up-turned flange restingagainst labial surface of incisors. Align midlinemark on up-turned flange with midsagittal ofmaxilla. With mandible retruded, have patient"bite down hard" on tray to adapt it to occlusalsurface of teeth (arrows).

Mix bite registration paste. Spread about 1mmthick on maxillary side of tray in perforated areasonly.

Wipe off excess registration paste that flowsthrough perforations onto madibular side of traywith gauze pad.

Note: For patients with deep anterior verticaloverlap, (for example, class II div. 2), cutcompletely across perforated occlusal areas oftray on both sides just anterior to serratedgripping areas (arrow). Have patient "bite down"hard on tray to adapt it to teeth. This will causemetal to overlap in canine areas, thus allowingposterior teeth to come closer together.

After removing crushed tray from patients mouth,dry tray with compressed air.

OPTIONAL: Dip entire bite tray briefly in bowl ofcold water before placing in the mouth.

Have patient use tongue to quickly lubricate teethwith saliva. Place loaded Bite-Tray in mouth andhold lightly against maxillary teeth (arrows).Instruct patient to tap mandibular teeth (inretruded position) against tray to assure tray isproperly repositioned.

While continuing to hold Bite-Tray in contact withmaxillary teeth (arrows) have patient open mouthslightly to separate mandibular teeth from tray.Hold tray against maxillary teeth in steady passivemanner until registration-paste hardens.

To remove Bite-Tray from patient’s mouth withoutwarping it, grasp tray with thumbs and indexfingers firmly on right and left flanges at premolararea; then shake tray vertically to break seal toteeth (arrows). Spraying mouth with cold watermay also be helpful in separating registration trayfrom teeth.

It is okay if maxillary occlusal and incisal contactsare made with the tray because tray is being heldin passive fashion against maxillary teeth.

Dip compound end of Bite-Tray about3-5 seconds in warm water (125°F / 40°C) totemper before placing in patient’s mouth.

While compound is still warm and pliable fitregistration to maxillary teeth. Hold tray againstmaxillary teeth with thumb and index finger ofone hand at lateral serrated areas of tray (bilateralarrows). Use thumb of other hand to hold lowerlip away from teeth. Place end of same thumbagainst labial surface of mandibular teeth.“Shake” mandible quickly two or three times whilepushing distally on lower anterior teeth to “break”muscle tension.

Have patient “relax jaw.” Continue to push distallywith forearm aligned in midsagittal plane ofpatient (this procedure may not be applicable forpatients with TMJ pain). Tell patient, “Do notbite, I will close your teeth for you”. Graduallyocclude teeth until mandibular incisors contactsoft compound (center vertical arrow) withoutposterior teeth touching tray.

As soon as mandibular incisors make properimpression in soft compound, instruct patient to“open your mouth quickly” (center arrow).Carefully remove tray from mouth withoutdisturbing soft compound.

Note: The following procedure is shown for righthanded operators. This should be consideredwhen done by left handed operators.

(If mandibular posterior teeth touching tray beforeanterior teeth touch compound, add morecompound to increase vertical dimension.However, keep vertical dimension to a minimumfor most accurate results.)

Check right and left sides of bite-tray with thickocclusal ribbon (e.g. .5mm) for absence ofmandibular posterior tooth contacts. If there iscontact, add more compound to increase verticaldimension and repeat procedure.

Note: If patient has unstable TM Joints, condylesmay go to higher position in fossae during brieftime patient is biting on hardened compoundregistration, thus causing lower posterior teethto come into contact with Bite-Tray.

Hold record firmly against maxillary teeth andhave patient tap mandibular incisors into retrudedcompound registration without assistance fromoperator to be sure index is comfortable,repeatable position for patient.

Note: Effects of head posture may be tested atthis time by having patient tip their head farbackward and far forward while tapping intoincisor registration to see if there are anydifferences.

Remove Bite-Tray from mouth and replace withcotton roll between incisors.

Add sufficient amount of bite registration paste(depending upon space between mandibularteeth and tray) to mandibular side of Bite-Tray tomake contact with mandibular posterior teeth.

OPTIONAL: Pending bite registration materialinstructions, dip entire tray 1-2 seconds in waterbefore placing in patient’s mouth.

Stand or sit behind patient (patient may be in asitting, straight up, 45°, or supine position). PlaceBite-Tray in patient's mouth and hold againstmaxillary teeth with index fingers at serratedflange areas (arrows). Have patient retrudemandible and place anterior teeth in retrudedcompound record. Instruct patient to hold teethin compound record with firm pressure, withoutclenching, until registration material hardens. (Itis important that patients do not clench whileregistration paste is setting in order to avoidflexing mandible and/or intruding lower anteriorteeth.) Do Not manipulate the mandible.

Note: The hardened anterior compound record(small horizontal arrow) represents apex of lateralborder movements and acts as a fulcrum. Largevertical arrows represent muscle forces whichseat condyles in superior anterior direction (smallcurved arrow). Normal physiologic centric relationposition may be defined as anywhere on the arcof closure with the condyles bilaterally seatedagainst the thin central bearing areas of theirrespective bi-concave discs in their most superior,anterior, medial position.
