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






2. During protrusive occ - ______ is considered undesirable






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






4. Retrognathic profile






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






6. Individual teeth from each arch can be involved in ________________ malocclusion






7. Relationship of the arches bone to bone;






8. Mandible moves to the right or left






9. Cervical 3rd






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






11. Horizontal distance of anterior teeth in crossbite






12. Position of the mandible relative to the maxilla during swallowing and other times when the jaw muscles contract






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






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






15. Class III (mal)occlusion of permanent teeth






16. Guidance for protrusive occ should be on the






17. Functional occlusion






18. 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






19. Middle 3rd






20. Maxillary - Mandibular - Facial






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






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






23. II (mal)occlusion






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






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






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






27. Primary teeth set ___________________ for permanent






28. Normal contacts between max. and mand. teeth; momentary contacts






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






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






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






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






33. Maxillary incisors are are lingual to mandibular incisors






34. Excessive occ force with adequate bone support =






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






36. Prognathic profile






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






38. When no teeth are contacting on this side






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






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






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

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






48. A continuation of the spee of to extend through the condyle






49. 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
