  • 3. •DEFINITION of ARTICULATOR:- A mechanical instrument that represents temporomandibular joints and jaws, to which mandibular and maxillary casts may be attached to stimulate some or all movements. www.indiandentalacademy.com
  • 4. CLASSIFICATION www.indiandentalacademy.com
  • 5. • INT. PROSTHODONTIC WORKSHOP AT UNIV. OF MICHIGAN-1972: • 1. Class I • Simple holding instruments capable of accepting single static registration. • Only vertical motion is acceptable. • e.g. J.B.Gariots, Barn-Door hinge. www.indiandentalacademy.com

  • 8. • 2. Class II- • Instruments that permit horizontal as well as vertical motion but do not orient the motion to T.M.J via face bow transfer. www.indiandentalacademy.com
  • 9. CLASS-II CLASS-IIA CLASS-IIB CLASS-IIC www.indiandentalacademy.com
  • 10. • Class II A- • Instruments in this class permit eccentric motion based on averages and will not accept facebow transfer. www.indiandentalacademy.com

  • 21. GYSI’ TRUBYTE ARTICULATOR www.indiandentalacademy.com
  • 22. Class IV- A •Instruments in this class will accept three dimensional dynamic registrations and utilize a facebow transfer. The condylar pathways engraved by the patient. •e.g. T.M.J articulator. www.indiandentalacademy.com
  • 23. TMJ ARTICULATOR www.indiandentalacademy.com
  • 24. Class IV-B •Instruments in this class will accept three dimensional dynamic registrations and utilize a facebow transfer. The condylar pathways can be selectively angled and customized. • e.g. Denar. www.indiandentalacademy.com

  • 27. www.indiandentalacademy.com
  • 28. www.indiandentalacademy.com
  • 29. USES OF ARTICULATORS www.indiandentalacademy.com
  • 30. • To hold opposing casts in a predetermined fixed relationship. • To diagnose dental occlusal conditions in both natural and artificial dentitions. www.indiandentalacademy.com
  • 31. • To plan dental procedures that involve positions; contours; & relationship of both natural and artificial tooth as they relate to each other. To aid in the fabrication of dental restoration and lost dental parts. www.indiandentalacademy.com
  • 32. • Articulators can be helpful in teaching and studying occlusion and mandibular movements. • To view the lingual occlusion. www.indiandentalacademy.com
  • 33. REQUIREMENTS OF AN ARTICULATOR www.indiandentalacademy.com
  • 34. • REQUIREMENTS. • Articulators must accurately maintain centric position. The patient’s casts must be easily removable and attachable to the articulator without loosing the horizontal and vertical relationship. www.indiandentalacademy.com
  • 35. • The articulator should be able to open and close in a hinge like fashion. The articulator should accept a facebow transfer. • The articulator should have an incisal guide pin with positive stop that is adjustable and calibrated. www.indiandentalacademy.com
  • 36. • For the complete denture construction in balanced occlusion. • Condylar guides should allow right lateral, left lateral and protrusive movements www.indiandentalacademy.com
  • 37. FACEBOW www.indiandentalacademy.com
  • 38. DEFINITION OF FACEBOW:- •A caliper like device used to record the relationship of maxillary arch to some anatomical reference point or points and then transfer the relationship to an articulator. www.indiandentalacademy.com
  • 39. www.indiandentalacademy.com
  • 40. USES OF FACE-BOW •1. It permits a more accurate use of lateral rotation points for the arrangement of teeth. •2. It aids in securing the anteroposterior cast position with relation to the condyles of the mandible. www.indiandentalacademy.com
  • 41. • 3. It registers the horizontal relationship of the casts quite accurately, and thus assists in correctly location the incisal plane. • 4. It is an aid in the vertical positioning of the casts on the articulator www.indiandentalacademy.com
  • 42. 1. Arbitrary facebow:-1. Arbitrary facebow:- Fascia facebow - EarpieceFascia facebow - Earpiece facebow - With orbital indicatorfacebow - With orbital indicator - With nasal relator- With nasal relator 2. Kinematic facebow2. Kinematic facebow www.indiandentalacademy.com
  • 43. • WHEN TO USE? www.indiandentalacademy.com
  • 44. 1. Cusp form teeth are used. 2. Balanced occlusion in eccentric position is desired. 3. A definite cusp fossa or cusp tip to cusp inclination is desired. 4. Interocclusal check records are used for verification of jaw positions.www.indiandentalacademy.com
  • 45. 5. The occlusal vertical dimension is subject to change, and the relations of the tooth occlusal surfaces are necessary to accommodate the change. 6. When there is significant error in antroposterior, lateral, vertical relations www.indiandentalacademy.com
  • 46. • To determine the position of the real condyle axis of motion. • Accurate mounting of casts in the articulator, both in relation to the position of the condyles and to certain points on the head. • www.indiandentalacademy.com
