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. Introduced the concept of codestruction






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






3. After periodontal sugery - mobility will ________






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






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






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






7. Growth hormone imbalance that causes the mandible to grow faster than the maxilla(all teeth are in crossbite)






8. 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






9. Mobility - migration - pain - premature contact - widening of PDL - parafuntional habits - TMJ problems - all result in _________






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






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






12. #10 & #23






13. Anterior; no horizontal overlap






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






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






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






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






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






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






20. Maxillary - Mandibular - Facial






21. Maxillary incisors are are lingual to mandibular incisors






22. Measurement of horizontal overlap w/ probe






23. A tooth that occludes with an opposing tooth before full closure is achieved in centric occlusion






24. 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






25. Horizontal distance of anterior teeth in crossbite






26. Tongue thrust or thumb sucking can cause






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






28. Above occlusal plane






29. Maximum touching of max and mand






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






31. Spaces between two teeth






32. Class III (mal)occlusion of permanent teeth






33. Mvmt of the mandible in a direction anterior to centric occ






34. Lateral mvmt results in contacct of all posterior teeth






35. Hereditary - Tongue - Intercuspation of teeth - Alignment of previously erupted teeth affects alignment of successive teeth






36. Rotated or twisted; rotated mesial or distal






37. Functional occlusion






38. Laterally






39. 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






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






41. During selective grinding - occlusion should be adjusted In what four relationships






42. Can affect the TMJ - muscles of mastication - pulp and integrity of restorations






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






44. Mandibular molars more distal than maxillary molars






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






46. When no teeth are contacting on this side






47. Mesognathic profile






48. Posterior; no horizontal overlap






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






50. Difference between primary and secondary occ trauma
