  • 1. INDIAN DENTAL ACADEMY Leader in continuing dental education
  • 2. Whip Mix Model #2340 Articulator
  • 3. The quick acting lock may be easily closed to the locked position by applying upward and backward pressure to the tab of the lock. In this position, accidental separation of the condylar guides from the condyles is prevented and simple hinge movement is allowed.
  • 4. #2321A and #2322A Condylar Guide Assemblies feature adjustable progressive slide shift and flat eminentia.
  • 5. The condylar inclination on the Model #2340 may be adjusted by loosening and then tightening the #8520 Screw to the appropriate setting.
  • 6. The progressive side shift may be set on the Model #2340 by loosening and then tightening the #8520A Side Shift Screw to the appropriate setting.
  • 7. A close up view of the Accumount mounting system. Each Model #2340 Articulator is calibrated in the factory to maintain a set relationship of the upper to the lower frame which allows the accurate transfer of mounted casts between articulators.
  • 8. Whip Mix Direct Mounting Face-Bows. From left to right, the Model #8645, #9600, and #8600 Face-Bows.
  • 9. The #8645 Direct Mounting Face-Bow features T-Screws and aluminum half-bows.
  • 10. Items packaged with each Face-Bow: • Face-Bow including Nasion Relator and Face-Bow Fork • Face-Bow Instruction Manual • Patient Record Card • Package of 6 Rubber Bands
  • 11. • Sterilize the bite fork and place registration material firmly over the top surface of the bite fork. • Position the bite fork so that the midline of the bite fork aligns with the midline of the maxilla. • Support the bite fork underneath by having the patient bite on cotton rolls. Some clinicians prefer to have the patient bite on the bite fork itself after registration material has been placed on both sides.
  • 12. • Before attempting to place the Face-Bow onto the bite fork, it is suggested that operator rehearse the following procedure with the patient. • A finger cot placed over each earpiece will help facilitate proper disinfection of the Face-Bow. • With the bite fork positioned in the patient’s mouth, have the patient grasp both arms of the Face-Bow and bring them backwards to a position just forward of the patient’s ears.
  • 13. Have the patient place each earpiece in the external auditory meatus and hold in place with firm pressure. Start the toggle onto the bite fork shift and make sure each earpiece is securely positioned.
  • 14. Center the plastic nosepiece on the patient’s nasion. Exert firm pressure on the nosepiece shaft while tightening the thumb screw of the nasion relator assembly.
  • 15. Tighten the three thumb screws (#8604) on top of the Face-Bow.
  • 16. Make sure the horizontal crossbar is above the bite fork shaft and push the #8642 toggle back on the bite fork shaft until it is near, but not touching, the lips. To prevent torquing of the Face-Bow and discomfort to the patient, support hand and tighten the the Face-Bow with one #8640 T-screw.
  • 17. Tighten the #8643 T-screw onto the vertical bar. Take care not to let the Face-Bow tip while tightening the T-screw.
  • 18. A permanent intercondylar width of 110 mm is incorporated into each Series 2000 Articulator. This corresponds to the ‘M’ setting found on the Face-Bow.
  • 19. When mounting a cast on a Series 2000 Articulator it is not necessary to record the intercondylar width marking designated by the SML markings on the upper arm of the Face-Bow.
  • 20.
  • 21. A finger cot placed over each earpiece will help facilitate proper disinfection of the Face-Bow. Remember, a rubber band correctly placed will aid Face-Bow manipulation.
  • 22. The following items are needed for mounting casts on the Model #2340 Articulator: • Mounting Stone or Mounting Plaster • Spatula • Rubber Bowl • Face-Bow Registration • 2- Clean Mounting Plates • Upper and Lower Casts • Interocclusal Records • Graduated Cylinder • Plaster Knife • Rubber Bands (optional)
  • 23. Remove or sufficiently raise the #2201 Incisal Guide Pin so that the upper member of the articulator will be able to rest on the horizontal crossbar of the Face-Bow.
  • 24. Place clean mounting plates (#8580 or #8580B) on the upper and lower frames of the articulator.
  • 25. Firmly tighten the Mounting Plate knob (#8507) whenever securing a mounting plate to the articulator.
  • 26. Set each condylar guide to the 30° setting on the condylar inclination scale in preparation for attaching the Face-Bow assembly to the upper frame of the articulator.
  • 27. Use the hex driver to firmly tighten each #8805 Clamp Screw.
  • 28. Set the progressive side shift guide setting to the 0 mark.
  • 29. Firmly tighten each #8520A Side Shift Screw.
  • 30. Place the Face-Bow in one hand and the upper member of the articulator in the other.
  • 31. Position the brass mounting pin located on the outer flange of the left condylar guide assembly into the hole on the medial side of the left plastic earpiece of the Face-Bow.
  • 32. While holding the left half-bow against one’s body, guide the right brass mounting pin into the right Face-Bow earpiece.
  • 33. Allow the anterior end of the upper frame of the articulator to rest on the horizontal crossbar of the Face-Bow. Securely tighten the 3 thumb screws on the top of the Face-Bow while still pressing the Face-Bow arms against one’s body.
  • 34. Because the guidance of this instrument is part of the upper frame and the Face-Bow is, in effect, one piece with this frame, the face-bow fork is in a fixed relation to the upper frame.
  • 35. Place the upper frame with attached Face-Bow onto the lower frame and make sure it is stable. The relation of the upper frame and its facebow fork registration to the lower frame and its condylar elements is of no consequence at this point since the lower frame serves merely as a convenient means of support during the mounting of the maxillary cast.
  • 36. Place the maxillary cast into the face-bow registration to make sure it is stable with no rocking. The cast will need additional trimming if the front end of the articulator upper frame does not contact the face-bow crossbar.
  • 37. • The Face-Bow Support (#8585) is a convenient accessory used to support the bite fork during the mounting of the upper cast. • The face-bow fork support attaches to the lower frame in place of the lower mounting plate. • The cross arm is raised to contact the under surface of the face-bow fork which prevents flexing of the fork.
  • 38. Some clinicians prefer to place rubber bands around the upper cast and bite for added stability.
  • 39. Lift the upper frame of the articulator and apply Mounting Stone to the base of the cast and the mounting plate. Whip Mix Mounting Stone is ideal for mounting casts because it is formulated to have a short working time, excellent stacking ability and extremely low setting expansion.
  • 40. Close the upper frame of the articulator until it contacts the face-bow crossbar and hold the upper frame in this position until the Mounting Stone is set. Do not use too thick a mix of Mounting Stone or attempt to apply force when the stone has already begun to set.
  • 41. It is not necessary that the Mounting Stone be smooth and all voids filled with the first mix. Many clinicians prefer to use a second mix to fill the voids after the first mix has set.
  • 42. • The upper and lower frames are made parallel by aligning the top of the pin boss with the dark line (zero mark) which completely encircles the incisal guide pin. • While mounting the lower cast it may be necessary to compensate for the thickness of the centric relation or maximum intercuspation record by raising the incisal guide pin 3-5 mm above the 0 mark.
  • 43. In preparation for mounting the lower cast, make sure the centric latch is secure.
  • 44. Place the articulator upside down with the incisal guide pin extending over the front edge of the work bench or table top. This positions the mounted cast with its occlusal surfaces upward.
  • 45. Place an interocclusal CR or MI registration on the maxillary cast. Make sure the record is completely seated on the maxillary cast.
  • 46. Position the mandibular cast on the CR or MI registration and check for stability. If preferred, attach a rubber band around the base of stability. lower cast to enhance
  • 47. Hinge the lower frame into an open position and apply Mounting Stone to the base of the lower cast and the lower mounting plate.
  • 48. • Hinge the lower frame closed until the incisal guide pin meets the incisal guide block. • Make sure the condylar elements are seated flush against the posterior and superior wall of the condylar guides. • Carefully hold the articulator in this position until the Mounting Stone has set.
  • 49. • Loosen the #8511 Incisal Guide Pin Screw and make sure the upper and lower casts contact. • Evaluate the occlusion of the casts to make sure they have been accurately mounted. • Retighten the incisal guide pin Screw and make sure the incisal guide pin is positioned in the center of the incisal guide table.
  • 50. Make sure the rounded end of the incisal guide pin is positioned in the guide table. of the plastic incisal
  • 51. After removing the CR or MI registration release the centric latch.
  • 52. Set both condylar guides to the 0 setting indicated on the condylar scale – firmly tighten the right condylar guide locking screw and lightly secure the left condylar guide locking screw.
  • 53. Set the progressive side shift guides to their most open position.
  • 54. Loosen the incisal guide pin screw and raise the incisal guide pin to prevent any interference, then retighten the screw.
  • 55. With the upper frame and its cast inverted, carefully seat the right lateral interocclusal record on the upper cast.
  • 56. Holding the upper frame in one hand and the lower frame in the other, place the right working condylar element in the right condylar guide. Make sure that the right condyle is seated and “flush” against the rear wall.
  • 57. Gently set the lower cast into the right lateral record and lightly hold the articulator and cast in position in the record.
  • 58. Notice that the left condylar guide element has moved away from both the superior and posterior surfaces of the condylar guide toward the medial wall.
  • 59. To set the inclination of the left condylar guide, rotate the guide until the superior wall touches the condyle element.
  • 60. Tighten the #8805 Left Condylar Guide Locking Screw to secure the condylar guide position. Do not use excessive pressure when tightening the locking screw.
  • 61. To set the left progressive side shift, loosen the left #8520A Side Shift Guide Holding Screw and move the #8524 Left Side Shift Guide until it touches the medial side of the left condyle element.
  • 62. Retighten the left #8520 Screw and return the articulator to its upright position. Record the amount of condylar inclination and immediate side shift found on the left side on a Patient Record Card.
  • 63. • After the left condylar guidance has been recorded the condylar guidance should be neutralized as previously described except that the left condylar guide locking screw should be tightened and the right condylar guide locking screw lightly secured. • The right condylar guidance is adjusted using the left lateral excursion record and repeating the procedure.
  • 64. • Many wish to set the condylar inclination of the articulator with the protrusive record. • To utilize the positive protrusive record, first neutralize the condylar inclination and progressive side shift setting. • Place the protrusive record on the inverted upper frame of the articulator and gently seat the lower cast in the protrusive record.
  • 65. Both condyle elements will have moved away from the posterior and superior surfaces of the respective condylar guides.
  • 66. • Using sight and touch, rotate the condylar guide until it contacts the condylar ball, then tighten the condylar locking screw. • Record the reading and repeat the procedure on the left side. • The lateral records are then used to determine the immediate side shift setting.
