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. Crowns tipped lingually - roots tipped laterally

6. Class III (mal)occlusion of permanent teeth






7. Posterior; no horizontal overlap






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






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






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






11. Relationship of the arches bone to bone;






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






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






14. #10 & #23






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






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






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






18. Radiographically - the PDL space is wider at the coronal third of the root






19. Maxillary anterior teeth stick out labially from tongue thrusting






20. ____ is not a sign of occl trauma






21. Tongue thrusting; thumb sucking - pacifiers






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






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






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






25. Anterior; no horizontal overlap






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






27. Survival of the dentition despite its deviation from a preconceived hypothetical normal






28. Middle 3rd






29. #7 - 26 - 27






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






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






32. Overlap of anterior teeth






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






34. What is not affected by occ trauma






35. Functional occlusion






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






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






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






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






40. 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






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






42. If the mandible moves to the left - the mvmt is known as a left working movement






43. 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






44. Abnormal contacts; occlusal habits - and neuroses






45. 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






46. Difference between primary and secondary occ trauma






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






48. Lateral mvmt results in contacct of all posterior teeth






49. Maxillary - Mandibular - Facial






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