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. Curved alignment of the occlusal plane when looking from a posterior view(right to left)






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






3. Maximum touching of max and mand






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






5. Mandible moves to the right or left






6. Teeth that are in func when the mandible moves in lateral or protrusive excursions or mvmts






7. 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






8. Starts around the mesial of the 1st molar






9. Associated with performance; all contacts during function of the oral cavity






10. Abnormal contacts; occlusal habits - and neuroses






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






12. Primary teeth set ___________________ for permanent






13. Mesially - Labially






14. Usually indicative of moderate to sever perio and secondary occ trauma






15. Retrognathic profile






16. Injury to the attachment apparatus (bone - PDL - and cementum) as a consequence of normal or excessive occ forces






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






18. Mandibular molars more distal than maxillary molars






19. II (mal)occlusion






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






21. Excessive occ force with adequate bone support =






22. Both sides






23. 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






24. Overlap of anterior teeth






25. After periodontal sugery - mobility will ________






26. Mand. retruded-one or more max. incisors retruded; max. laterals protruded-max centrals retruded; crowded max anterior teeth; deep overbite






27. Crowns tipped lingually - roots tipped laterally






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






29. Maxillary - Mandibular - Facial






30. Starts closer to premolars






31. Vibrational mvmt of a tooth under occ function






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






33. Overclosure of the anterior teeth can cause trauma to the gingiva of the max teeth






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






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






36. Anterior crossbite; max/mand incisors-edge to edge occlusion; crowded mand. incisors






37. The permanent molars erupt posterior to the primary teeth and push them all mesially






38. Horizontal






39. Curve spee & wilson - 3-d - not proven






40. Maximal intercuspation or contact of the max and mand teeth






41. Functional occlusion






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






43. Vertical






44. Maxillary anterior teeth stick out labially from tongue thrusting






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






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






47. When no teeth are contacting on this side






48. Contact between maxillary incisors does not line up with contact of mandibular incisors






49. Mandibular molars and maxillary molars are even






50. Incisal 3rd
