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. Tooth positioned more lingual






2. Does not result from brushing at all - but from traumatic lateral forces placed on the teeth as a result of a malocclusion or abnormal tongue activity. Root surface is exposed & can become carious






3. Buck teeth are common and are considered






4. Widening of the PDL in areas under pressure results due to






5. Mesially - Labially






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






7. Congenitally missing teeth - Impacted teeth & size and shape of muscle and bone






8. II (mal)occlusion






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






10. Later






11. Incisal 3rd






12. Curved alignment of the occlusal plane when looking from a lateral view(distal to mesial)






13. Spaces between two teeth






14. Aquired centric occlusion - habitual occlusion - convienience occlusion - or intercuspal position






15. Curve of the occlusal plane; from anterior to posterior - increases with age






16. Primary teeth set ___________________ for permanent






17. Retrognathic profile






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






19. Vibrational mvmt of a tooth under occ function






20. Starts closer to the posterior of the 1st molar






21. Any occl that produces forces that directly or indirectly cause injury to the attachment apparatus






22. Lateral mvmt results in contacct of all posterior teeth






23. Abnormal contacts; occlusal habits - and neuroses






24. Above occlusal plane






25. Maxillary - Mandibular - Facial






26. Functional occlusion






27. 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






28. 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






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






30. Starts closer to premolars






31. Excessive deposition of cementum around the apex - due to excessive occlusal forces






32. 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






33. The side to which the mandible moves(chewing side)






34. What is not affected by occ trauma






35. During protrusive occ - ______ is considered undesirable






36. Vertical






37. Mand. facial or lingual to max. - unitlateral or bilateral; incorrect horizontal overlap






38. Mandibular molars and maxillary molars are even






39. Difference between primary and secondary occ trauma






40. Max. incisors lingual to mand. incisors; incorrect horizontal overlap






41. Introduced the concept of codestruction






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






43. Maxillary anterior teeth stick out labially from tongue thrusting






44. ____ is not a sign of occl trauma






45. Because the permanent premolars are narrower than the primary molars that they replace - this is what happens when the premolars erupt






46. Starts around the mesial of the 1st molar






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






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






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






50. Middle 3rd
