Articulators

  1. 1. ARTICULATORS Deepak K Gupta Institute of Dental Education and advance studies, Gwalior
  2. 2. • articulator may be defined as a mechanical device that represent the temporomandibular joint and jaw members to which maxillary and mandibular ccaassttss mmaayy bbee aattttaacchheedd ttoo ssiimmuullaattee jaw movement. Deepak Kumar Gupta dr.dkg07@gmail.com
  3. 3. PURPOSES • To hold the maxillary and mandibular casts in a determined fixed relationship • Mounting of dental casts for diagnosis treatment planning and patient presentation. • TToo ssiimmuullaattee tthhee jjaaww mmoovveemmeenntt lliikkee ooppeenniinngg aanndd closing. • Fabrication of occlusal surfaces for dental restoration. • Arrangement of artificial teeth for complete and removable partial denture Deepak Kumar Gupta dr.dkg07@gmail.com
  4. 4. USES • To diagnose the state of occlusion in both the natural and artificial dentition. • To plan the dental procedures based on the relationship between opposing natural and artificial teeth. EExx.. EEvvaalluuaattiioonn ooff tthhee ppoossssiibbiilliittyy ooff bbaallaannccee occlusion. • To aid in the fabrication of restorations and prosthodontics replacements. • To correct and modified complete restorations. • To arrange artificial teeth. Deepak Kumar Gupta dr.dkg07@gmail.com
  5. 5. The relationship of mandible to maxilla can be transferred from pt to the articulator 3 records Hinge axis records Interocclusal records 1. Face bow 2. Centric jaw Graphic records relation record 3. Protrusive record. 4. Lateral records 5. Intercondylar distance record Deepak Kumar Gupta dr.dkg07@gmail.com
  6. 6. REQUIREMENTS • Two Types of Requirements – Minimal requirements –– AAddddiittiioonnaall rreeqquuiirreemmeennttss Deepak Kumar Gupta dr.dkg07@gmail.com
  7. 7. Minimal requirements • They are necessory for the fabrication of complete denture to the patients centric position. • They are – – It must bbee aaccccuurraatteellyy mmaaiinnttaaiinn tthhee ccoorrrreecctt hhoorriizzoonnttaall and vertical relationship of the patient’s casts. – The casts should be easily removable and attachable to the articulator without loosing their correct horizontal and vertical relationship – The articulator should have an incisal guide pin with a positive stop, that is adjustable and caliberated. the articulator should be able to open and closed in a hinge like fashDeieopank K.umar Gupta dr.dkg07@gmail.com
  8. 8. Minimal requirements – The articulator should accept a face-bow transfer utilizing an anterior reference point. – The construction should be accurate, rigid and of non corrosive material. – The moving parts should move freely without any ffrriiccttiioonn.. – The non moving parts should be of a rigid construction. – The design should be such that there is adequate distance between the upper and lower members. – The articulator should be stable on the laboratory bench and not too bulky and heavy Deepak Kumar Gupta dr.dkg07@gmail.com
  9. 9. ADDITIONAL REQUIREMENT • The condylar guides should allow right lateral, left lateral and protrusive movement. • The condylar guides should be adjustable horizontally. • TThhee aarrttiiccuullaattoorr sshhoouulldd hhaavvee pprroovviissiioonn ffoorr adjustment of Bennett movement. • The incisal guide table should be mechanical table that can be adjusted in the sagittal and frontal planes or a table that can be customised with autopolymerizing resin or by grinding. Deepak Kumar Gupta dr.dkg07@gmail.com
  10. 10. ADVANTAGES • Properly mounted casts allow the operator to better visualize the patients occlusion, especially from lingual view. • Patient cooperation is not a factor when using an articulator. once appropriate interocclusal records are obtained from the patient. • reduces the chair time, patient appointment time. • The refinement ooff ccoommpplleettee ddeennttuurree oocccclluussiioonn iinn tthhee mmoouutthh iiss extremely difficult because of shifting denture bases and resiliency of the supporting tissue. • Inter occlusal records can be obtained and complete denture occlusion can be refined outside the mouth on an articulator. • More procedures can be delegated to auxillary personnel when utilizing an articulator for development of patients occlusion. • The patients saliva, tongue, and cheeks are not factors when using an articulator. Deepak Kumar Gupta dr.dkg07@gmail.com
  11. 11. LIMITATIONS • Metal,plastic articulators show errors in tooling, (manufacturer). • It not exactly simulate the intraborder and ffuunnccttiioonnaall mmoovveemmeennttss ooff tthhee mmaannddiibbllee.. • Errors in jaw relation procedure are reproduced as errors in the denture occlusion. Articulators do not have any provision to indicate or correct these errors. Deepak Kumar Gupta dr.dkg07@gmail.com
  12. 12. CLASSIFICATION OF ARTICULATORS • Several basis of classification of articulator were proposed, some of them are as follows. – Based on the instruments function. –– BBaasseedd oonn tthheeoorriieess ooff oocccclluussiioonn.. – Based on the type of inter occlusal record used. – Based on the adjustabililty of the articulator Deepak Kumar Gupta dr.dkg07@gmail.com
  13. 13. BASED ON INSTRUMENT FUNCTION • Ability to simulate the jaw movement • At the international prosthodontic workshop on complete denture occlusion at the University of Michigan in 1972, the articulators classified based on – instrument capability, –– iinntteenntt,, – recording procedure – record acceptance • Class I : Hinge Type • Class II : Arbitrary – type A, type B, type C • Class III : Average -type A, type B • Class IV : Special – type A, type B Deepak Kumar Gupta dr.dkg07@gmail.com
  14. 14. CLASS I (Hinge Type) • simple articulator (Simple holding instruments) capable of accepting a single static registration. • Only Vertical motion possible. •• ppoossiittiivvee ssttooppss aanndd lloocckkss aatt tthhee mounted position • Use in cases where a tentative jaw relation is done • for crown and bridge, and operative instruments • Example : Slab articulator, Hinge joint articulator (J.B.

  17. 17. CLASS II (Arbitary) • These articulator permits horizontal and vertical movements but they do not orient the movement to TMJ a face-bow • Type A – Eccentric motion is unrelated to patient motion. – Permit limited eccentric motion based on averages – The condyles are on the lower member of articulator – Based on Bonwill’s triangle – EExx.. MMeeaann--VVaalluuee aarrttiiccuullaattoorr,, GGYYSSII • TYPE B – Permit limited eccentric motion based on arbitrary theory of motion – Based on spheric theory of occlusion – Ex: Monson’s articulator - Spherical Theory Articulator – Fournet & Hageman articulators, Hall’s articulator -Conical Theory Articulator, Shofu Handy II • TYPE C – Permit limited eccentric motion based on engraved records obtained from the patient • Ex: House’s articulator (1920) , Gnathic Relator Deepak Kumar Gupta dr.dkg07@gmail.com
  18. 18. House Articulator Deepak Kumar Gupta dr.dkg07@gmail.com
  19. 19. CLASS III (Average) • They permit horizontal and vertical motion • Do accept face-bow transfer but these facility is limited • Do Not / Cannot allow total customization of condylar pathways • They simulate condylar pathways by using average or mechanical equivalents for the whole or part of the condylar motion • They allow for joint orientation of the casts and may be arcon or nnoonnaarrccoonn iinnssttrruummeennttss • fulfill the requirements for complete denture construction • good centric lock, progressive and immediate side shift controls • protrusive inclination, intercenter distance adjustment • a simple mounting procedure, a good sturdy design, and an arcon arrangement • All the examples are arcon instruments, accept facebows, and have mounting plates for unlimited case load Deepak Kumar Gupta dr.dkg07@gmail.com
  20. 20.

  79. 79. SELECTION OF AN ARTICULATOR One should not used too complex instruments for a simple case or too simple articulator for a complex case. The following factors pertinent to the understanding and selections: • Articulator movements of the condylar elements do not reproduced condylar movementin the temporomandibular jjooiinntt.. • The goals of articulation is to duplicate tooth movements along border path ways in at least to planes of space. • The most important requirment of an articulator are to maintain centric relation & the vertical dimension of occlusion. • Fixed condylar elements at 110mm are all that is neccesary. An adjustable inter condylar capability may permit more records to be accepted. Deepak Kumar Gupta dr.dkg07@gmail.com
  80. 80. SELECTION OF AN ARTICULATOR • The articulator should be able to receive a face-bow transfer record,. • The articulator should have the capability of adjustment for precurrent or immediate side shift upto atleast 2.5 mm. •• AAnn aaddjjuussttaabbllee mmeecchhaanniiccaall iinncciissaall gguuiiddee ttaabbllee ccaann nnoott reproduce the natural guidance of the anterior teeth. • A sterograph ( pantograph) has limited value for all but a few types of prosthodontics situation. • The sophistication of articulators should not exceed the level of training & ability of the personnel that will be fabricating the restorations Deepak Kumar Gupta dr.dkg07@gmail.com
