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. When no teeth are contacting on this side






2. Both sides






3. After periodontal sugery - mobility will ________






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






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






6. 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






7. Rotated or twisted; rotated mesial or distal






8. II (mal)occlusion






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






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






11. Occlusal forces will accelerate the rate of perio destruction and result in CT attachment loss in the presence of preexisting inflammation






12. Tooth positioned more facial






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






14. Guidance for protrusive occ should be on the






15. #7 - 26 - 27






16. Mesially - Labially






17. Primary teeth set ___________________ for permanent






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






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






20. Symptom free dentition that 'survives' or 'adapts' to a deviated occl






21. Posterior; no horizontal overlap






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






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






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






25. Any deviation from the ideal or normal occl. includes crowding - malpositioned or tipped teeth






26. Anterior; no horizontal overlap






27. Maxillary - Mandibular - Facial






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






29. Anterior or posterior; bilateral or unitlateral - anterior more common






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






31. Habitual - acquired - convenience - intercuspal & static






32. Class III (mal)occlusion of permanent teeth






33. Horizontal






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






35. Lateral mvmt results in contact btwn the max and mand canines






36. Mesognathic profile






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






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






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






40. Above occlusal plane






41. Vibrational mvmt of a tooth under occ function






42. During protrusive occ - ______ is considered undesirable






43. Occlusal guard =






44. Retrognathic profile






45. Tooth extracted






46. Tooth positioned more lingual






47. Patient forces teeth together in centric occlusion on one side to get a more functional bite and has a crossbite on the other side(the midline of the maxillary anterior teeth does not line up with the midlineof the mandible






48. 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






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






50. What is not affected by occ trauma
