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. Functional occlusion






2. Mandibular molars more distal than maxillary molars






3. Crowns tipped lingually - roots tipped laterally






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






5. The relationship of the teeth in the mandibular arch to those in the maxillary arch as they are brought together






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






7. Muscles that work the jaw; may become sore due to occ trauma






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






9. Incisal 3rd






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






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






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






13. Tongue thrust or thumb sucking can cause






14. Vertical overlapping






15. Abnormal contacts; occlusal habits - and neuroses






16. Middle 3rd






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






18. Horizontal distance of anterior teeth in crossbite






19. The way you normally bite your teeth together when not chewing






20. Vibrational mvmt of a tooth under occ function






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






22. Malposition - crowded anterior teeth - protruded or retruded max incisors - anterior/posterior crossbite - mesial drift






23. Both sides






24. During protrusive occ - ______ is considered undesirable






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






26. Habitual - acquired - convenience - intercuspal & static






27. Above occlusal plane






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






29. Measurement of horizontal overlap w/ probe






30. Later






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






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






33. Tongue thrusting; thumb sucking - pacifiers






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






35. Prognathic profile






36. Tooth positioned more lingual






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






38. Spaces between two teeth






39. Retrognathic profile






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






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






42. Maxillary - Mandibular - Facial






43. Excessive occ force with adequate bone support =






44. Below occlusal plane






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






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






47. Vertical






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






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






50. What is not affected by occ trauma
