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. Rotated or twisted; rotated mesial or distal






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






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






4. Curve of the occlusal plane; from anterior to posterior - increases with age






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






6. Need tooth to tooth contact on both working and non working sides to func effectively






7. Mandibular molars and maxillary molars are even






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






9. Tongue thrust or thumb sucking can cause






10. II (mal)occlusion






11. The patient is constantly tightening the lower lip against the lower anterior teeth causing the the mandibular teeth to be pushed back into the mouth by this overdeveloped lower lip






12. Middle 3rd






13. Later






14. Abnormal contacts; occlusal habits - and neuroses






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






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






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






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






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






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






21. Lateral mvmt results in contacct of all posterior teeth






22. Tooth extracted






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






24. Maxillary - Mandibular - Facial






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






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






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






28. Prognathic profile






29. Starts closer to premolars






30. Teeth that are in func when the mandible moves in lateral or protrusive excursions or mvmts






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






32. Mandible moves to the right or left






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






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






35. 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






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






37. When no teeth are contacting on this side






38. High restoration - parafunctional habits - malpositioned tooth - periapical abcess - physical 'blow' - removable partial - ortho mvmt






39. Retrognathic profile






40. Vertical overlapping






41. Guidance for protrusive occ should be on the






42. Because the permanent premolars are narrower than the primary molars that they replace - this is what happens when the premolars erupt






43. Starts around the mesial of the 1st molar






44. Maximum interlocking of cusp






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






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






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






48. Widening of the PDL in areas under pressure results due to






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






50. Mesially - Labially
