Mounting the Mandibular CastAttach a mounting plate to the lowerbow. A centric relation checkbite recordis used to mount the mandibular cast.With the maxillary cast attached tothe articulator and the centric locksengaged, invert the articulator and placethe centric relation checkbite recordbetween the maxillary and mandibularFIG. 24Place the maxillary cast in the wax indexon the bitefork, close the articulator,and mount the cast with stone to themounting plate (See Fig. 25) . Normally, amaxillary cast support is not necessary,although one may be used, if desired.Once the stone has hardened, removethe transfer jig and replace the incisaltable in the articulator.FIG. 25FIG. 26casts (See Fig. 26). Stabilize the positionof the casts with either a rubber bandor sticky wax. Adjust the incisal pin toaccommodate the increased verticaldistance caused by the thickness of thecentric relation bite record.14
Double check to be certain that thecondyles are seated against the rear ofthe fossae, and using stone, proceed tomount the mandibular cast to the mountingplate on the articulator (See Fig. 27).FIG. 27IV SETTING THECONDYLAR CONTROLSThe Track <strong>II</strong> articulator features threecondylar path of movement adjustments:1) protrusive condylar path; 2) progressivesideshift and 3) immediate sideshift.The operator may select any of the followingalternate methods for makingthese adjustments dependent upon hisor her specific requirements and preference.PROTRUSIVE1. Arbitrary method. Set to 30 degrees.(This inclination is sufficiently low toeliminate almost all protrusive interference.)2. Checkbite method. Loosen the protrusiveand progressive sideshift adjustmentson both sides of the articulator.Disengage the centric positioner. Setthe protrusive checkbite record oneither cast. Move the opposing cast inthe protrusive position and seat it intothe checkbite record. If the cast doesnot seat accurately, apply very lightpressure to the bow of the articulatorand rock the protrusive adjustmentsback and forth until the most accurateseating of the casts into the recordis achieved (Fig. 28). (This proceduremust be done very carefully so as notto modify the record.) Lock the protrusiveand progressive sideshift adjustmentlock screws.PROGRESSIVE SIDESHIFTa. Average Anatomic Setting: = 7°b. Arbitrary Setting: = 7+°c. Lateral Checkbite (procedureexplained below without incorporatingthe immediate sideshift)15
