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. Anterior; no horizontal overlap






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






3. Severe ging inflammation extending into CT attachment - loss of supporting alveolar bone - pregnancy - ortho mvmt - and surgical therapy - may all cause ______






4. Mandibular molars and maxillary molars are even






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






6. Habitual - acquired - convenience - intercuspal & static






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






8. Rotated or twisted; rotated mesial or distal






9. Tooth extracted






10. What is not affected by occ trauma






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






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






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






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






15. Primary teeth set ___________________ for permanent






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






17. Maxillary anterior teeth stick out labially from tongue thrusting






18. Maxillary-between canines and laterals - mandibular-between canines and 1st molars






19. Slight buccal inclination of crown - lingual inclination of root






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






21. 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






22. Transverse occlusal curvature; posterior teeth; medio-lateral postion (r-l)






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






24. Relationship of the arches bone to bone;






25. Middle 3rd






26. Below occlusal plane






27. Max canine occludes with mand. canine and mand. 1st premolar.






28. #10 & #23






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






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






31. Maxillary overlap mandibular; whole arch






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






33. Mandible moves to the right or left






34. ____ is not a sign of occl trauma






35. Functional occlusion






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






37. Overlap of anterior teeth






38. Maximum interlocking of cusp






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






40. Above occlusal plane






41. Relationship of the teeth in opposite arches; static position






42. Laterally






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






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






45. Tooth positioned more facial






46. Cervical 3rd






47. Measurement of horizontal overlap w/ probe






48. The tooth has insufficient bone support and normal chewing and swallowing forces are excessive - causing injury to the attachment appartatus






49. Most common cause is when the maxilla does not grow in proportion to the mandible






50. Mesially - Labially
