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






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






3. Middle 3rd






4. Tongue thrust or thumb sucking can cause






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






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






7. Horizontal distance of anterior teeth in crossbite






8. Occlusal guard =






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






10. Habitual - acquired - convenience - intercuspal & static






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






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






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






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






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






16. Introduced the concept of codestruction






17. Teeth are misaligned when biting together






18. Vertical overlapping






19. Starts closer to premolars






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






21. #7 - 26 - 27






22. 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






23. Spaces between two teeth






24. Patients show evidence or signs and syptoms of occ disease






25. Most retruded position of the mandible in relation to the maxilla From which lateral mvmts of the jaw can be made






26. Excessive occ force with adequate bone support =






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






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






29. 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






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






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






32. Maxillary - Mandibular - Facial






33. Prognathic profile






34. When no teeth are contacting on this side






35. ____ is not a sign of occl trauma






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






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






38. Tooth positioned more facial






39. Rotated or twisted; rotated mesial or distal






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






41. Relationship of teeth in which the incisal ridges or buccal cusp ridges of the maxillary anterior teeth extend facially to the incisal ridges/cusps of the mandibular teeth when the teeth are in centric occlusion relationship






42. Mandibular molars and maxillary molars are even






43. Abnormal contacts; occlusal habits - and neuroses






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






45. Vibrational mvmt of a tooth under occ function






46. Mesognathic profile






47. Class III (mal)occlusion of permanent teeth






48. #10 & #23






49. Mandibular molars more distal than maxillary molars






50. Functional occlusion
