Dentistry Occlusion

Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Maximal intercuspation or contact of the max and mand teeth






2. Need tooth to tooth contact on both working and non working sides to func effectively






3. Reshaping of the occ or incisal surfaces of teeth to create contacts btwn upper and lower dentition






4. Relationship of the teeth in which the incisal ridges of the maxillary anterior teeth extend below the incisal edges of the mandibular anterior teeth when the teeth are placed in a centric occlusal relationship






5. Laterally






6. The way you normally bite your teeth together when not chewing






7. Permits healing of the attachment apparatus by holding a tooth in a totally fixed position; allows the PDL to become narrower and the mobility to be reduced






8. Can be caused by forces of malocclusion - teeth can become loose - periodontal disease may develop(alveolar bone loss)






9. II (mal)occlusion






10. Lateral mvmt results in contacct of all posterior teeth






11. Tooth positioned more facial






12. Prognathic profile






13. When one tooth hits before all others when closing teeth together(may cause TMJ problems)






14. Crowns tipped lingually - roots tipped laterally






15. Spaces between two teeth






16. Malocclusion cause excessive incisal or occlusal wear(attrition); teeth continue to erupt in order to occlude with teeth in the opposite arch & roots become exposed






17. Tongue thrust or thumb sucking can cause






18. Deciduous molars and canines are wider than permanent premolars and canines; space saved during mesial drift of permanent molars






19. Maximum interlocking of cusp






20. Selective grinding should always be completed after ______ has been controlled






21. During a left working movement - the right side is known as the






22. The patient is constantly tightening the lower lip against the lower anterior teeth causing the the mandibular teeth to be pushed back into the mouth by this overdeveloped lower lip






23. Retrognathic profile; buccal groove of mand 1st molar-distal to mb cusp of max 1st; distal of mand. canine distal to mesial to max caniine - tendency toward class II






24. Primary teeth set ___________________ for permanent






25. Mb cusp of max 1st molar-buccal groove of mand 1st molar






26. Anterior teeth do not occlude - or remain open - while posterior teeth may have a normal occlusion






27. Maxillary overlap mandibular; whole arch






28. Maximum touching of max and mand






29. Cervical 3rd






30. The relationship of the teeth in the mandibular arch to those in the maxillary arch as they are brought together






31. When the jaws are closed - the buccal cusps of the mandibular posterior teeth are interlocked between the buccal & lingual cusps of the maxillary teeth






32. If the mandible moves to the left - the mvmt is known as a left working movement






33. Retrognathic profile -buccal groove of mand. 1st molar-distal to mb cusp of 1st max.molar -distal of mand canine distal to mesial of max canine - tendency towards class II






34. Measurement of horizontal overlap w/ probe






35. Mesognathic profile






36. Maxillary anterior teeth stick out labially from tongue thrusting






37. Mandibular molars more mesial than maxillary molars (most children)






38. High restoration - parafunctional habits - malpositioned tooth - periapical abcess - physical 'blow' - removable partial - ortho mvmt






39. Tooth-tooth contacts; tooth-hard objects contacts; tooth-oral tissues contact






40. Relationship of the arches bone to bone;






41. Cusps of maxillary teeth directly over cusps of mandibular teeth

43. Below occlusal plane






44. Functional occlusion






45. Most retruded position of the mandible in relation to the maxilla From which lateral mvmts of the jaw can be made






46. Horizontal






47. Survival of the dentition despite its deviation from a preconceived hypothetical normal






48. Mand. retruded-max. incisors protruded; deep overbite; excessive overjet - abnormal muscle function - short mandible - short upper lip






49. After periodontal sugery - mobility will ________






50. Position of the mandible relative to the maxilla during swallowing and other times when the jaw muscles contract
