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






2. Relationship of the teeth in which the incisal ridges of the maxillary anterior teeth extend below the incisal edges of the mandibular anterior teeth when the teeth are placed in a centric occlusal relationship






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






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






5. Vibrational mvmt of a tooth under occ function






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






7. Introduced the concept of codestruction






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






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






10. Tooth positioned more facial






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






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






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






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






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






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






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






18. Functional occlusion






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






20. Tongue thrusting; thumb sucking - pacifiers






21. Aquired centric occlusion - habitual occlusion - convienience occlusion - or intercuspal position






22. Guidance for protrusive occ should be on the






23. Maximum touching of max and mand






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






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






26. After periodontal sugery - mobility will ________






27. Relationship of the arches bone to bone;






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






29. Abnormal contacts; occlusal habits - and neuroses






30. II (mal)occlusion






31. Above occlusal plane






32. 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






33. Spaces between two teeth






34. During protrusive occ - ______ is considered undesirable






35. Mesially - Labially






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






37. Tooth extracted






38. Mandibular molars and maxillary molars are even






39. Mesognathic profile






40. #10 & #23






41. Excessive occ force with adequate bone support =






42. Class III (mal)occlusion of permanent teeth






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






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






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






46. Habitual - acquired - convenience - intercuspal & static






47. Mandibular molars more distal than maxillary molars






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






49. Later






50. When no teeth are contacting on this side
