Instruction Manualmark 300 articulator systemArticulator ManipulationsTo attach the incisal pin, thread thetop thumbscrew into the opening onthe front of the upper member until itslides back as far as it will go. Tightenthe top thumbscrew (figure 1).To assemble the articulator, hold theupper member approximately parallelto the lower member and simply placeit on the lower member.IMPORTANT: We recommend usingthe incisal pin to put the articulatorthrough excursive movements ratherthan the casts. Pushing on the castsmay affect accuracy.Centric Latch OperationWhen the articulator is closed it canbe locked in the centric position bypushing the centric latch to the downposition (figure 2).Support PinThe built in support pin allows the uppermember of the articulator to standcompletely open while the articulatoris setting flat (figure 3). To ensurethe support pin remains in position,use the red lock pin to hold the liftedsupport pin in place. With the articulatorfacing you, lift the support pin andpush the lock pin to the right (blacko-ring exposed) to lock in place (figure4). To lower the support pin, first pushthe lock pin to the left.Fig. 1Fig. 2Fig. 3Fig. 45

Denar Mark 300 Series Articulator SystemFig. 5Articulator AdjustmentsThe articulator is a mechanical equivalent ofthe lower half of the head – a mechanical jawso to speak. In order to discuss the adjustmentsof the articulator or specifically thefossa controls, it would be helpful to discussthe condylar paths of movement of the humanmandible. In a lateral mandibular movementthe condyle on the side toward whichthe mandible moves is termed the rotatingcondyle (figure 5). The condyle on the side oppositethe side towards which the mandiblemoves is termed the orbiting condyle.In a lateral mandibular movement the orbiting condyle movesinward, downward and forward and orbits about the rotating condylewhich is simultaneously rotating and moving outward duringthe lateral mandibular movement.• Orbiting path – the path of movement of the orbiting condyle.• Rotating path – the path of movement of the rotating condyle.• Protrusive path – the path of movement of the condyles in astraight protrusive movement.The Mark 300 System has been designed for simplicity andefficiency. The different Models allow different levels ofadjustment and enable Clinicians to choose based on their needs.Model 330 incorporates a complete range of adjustments:Protrusive Condylar Inclination, Immediate Side Shift and ProgressiveSide Shift.Model 320 allows Protrusive adjustment but Progressive SideShift is fixed at 15˚ thus eliminating any chance of balancing sideocclusal contact.Model 310 incorporates anatomical averages based on clinicalresearch. Protrusive movement is fixed at 25˚ and Progressive SideShift is fixed at 15˚. The angles were selected as offering the leastamount of interference, based on studies by Dr. Harry Lundeenand Dr. Carl Wirth.6

Instruction ManualProtrusive AdjustmentsProtrusive Condylar Inclination: the angleof the fossa in relation to the occlusalplane.Model 330 Model 320 The inclinationof the protrusive condylar path can beadjusted by loosening the protrusiveadjustment thumbscrew. The protrusivecondylar path inclination scale is belowthe protrusive adjustment thumbscrewand is calibrated in increments of 5degrees (figure 6). The protrusive adjustment range is 0 – 60degrees.Fig. 6Immediate Side Shift AdjustmentImmediate Side Shift: a mandibular sideshift in which the orbiting condyle movesessentially straight medially as it leavescentric relation.Model 330 The medial fossa wall canbe displaced straight medially by meansof the immediate side shift adjustment.The scale for the immediate side shiftadjustment is lateral to the protrusiveadjustment thumbscrew on top of thefossa. The scale is calibrated in 0.5 millimeterincrements on the upper scaleand 1 millimeter increments on the lowerscale. Figure 7a shows an immediate sideshift of 0 mm. To set the immediate sideshift, loosen the thumbscrew below thescale and align the marks of the lowerscale with either the long mark of the upper scale for shifts of 1 or2 mm, or with the smaller marks for shifts of 0.5 or 1.5 mm. Figure7b shows an immediate side shift setting of 1.5 mm. The immediateside shift range is 0 – 2 mm.Once you have set the immediate side shift, tighten down on thethumbscrew. This will hold immediate side shift in place as youuse the Bennett lever to adjust progressive side shift.Fig. 7aFig. 7b7

Denar Mark 300 Series Articulator SystemProgressive Side Shift AdjustmentProgressive Side Shift: the path the orbiting condylefollows on the medial wall of the fossa as itorbits around the rotating condyle.Fig. 8Fig. 9Fig. 10Model 330 The angle of inclination of themedial fossa wall to the sagittal plane can be adjustedby moving the progressive side shift Bennettlever from 0 to 15 degrees. The scale for theprogressive side shift adjustment is beside theadjustment thumbscrew and is calibrated in 5degree increments (figure 8). Once immediateand progressive side shift are set, tighten thethumbscrew to ensure the settings stay as needed.Mounting a cast on the Mark 300 SeriesIn addition to a facebow recording (figure 9) the only recordsneeded for complete programming of the Mark 300 Series are:a lateral bite recorda centric relation bite recorda protrusive bite recordIf anterior teeth are to be restored, a customizedanterior guidance table is fabricated toprecisely copy the desired guidance.The Slidematic facebow is used to recordcondylar axis (figure 9).The upper cast is related to the condylar axis.The index for the facebow fork corrects theposition of the cast to relate it to the condylaraxis instead of the ear holes. This is an automaticcorrection (figure 10).Make sure that mounting plate divotsare clean of all dust, dirt or other debrisbefore mounting casts.NOTE: To enhance accuracy, the mountingplates have been designed so that they donot fit perfectly flat against the articulatormember. You may notice a slight gap.8

Instruction ManualA centric relation bite record is made(figure 11).Fig. 11The lower cast is related to the uppercast by alignment into the centric relationrecord (figure 12).Fig. 12The completed mounting permitsclosure of the casts to contact in centricrelation (figure 13).Fig. 13IMPORTANT: We recommendusing the incisal pin to put thearticulator through excursivemovements rather than thecasts. Pushing on the casts mayaffect accuracy.9

Denar Mark 300 Series Articulator SystemAccessoriesDenar® Slidematic FacebowThe time-saving design of this device eliminatesthe need for transferring the entire facebow tothe articulator. It is a fast, easy and accurate meansof transferring the proper maxillary relationships.Transfer only the transfer jig assembly to the articulatorthus freeing the measuring bow to be used forthe next patient.Simplified Occlusal Plane AnalyzerDesigned for analyzing the Curve of Spee and theCurve of Wilson.Occlusa-Check®Used for the detection of occlusal interferences ofrestorations while they are still on the articulator.When the pin locks into the slot, the restorationis the correct height. If the restoration is built toohigh, the pin will not go into the slot.10
