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. Difference between primary and secondary occ trauma






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






3. Horizontal distance of anterior teeth in crossbite






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






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






6. Maximum interlocking of cusp






7. Vertical






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






9. Tooth positioned more facial






10. Anterior; no horizontal overlap






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






12. Maxillary incisors are are lingual to mandibular incisors






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






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






15. When no teeth are contacting on this side






16. 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






17. Measurement of horizontal overlap w/ probe






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






19. Maxillary overlap mandibular; whole arch






20. Maxillary - Mandibular - Facial






21. Can be caused by forces of malocclusion - teeth can become loose - periodontal disease may develop(alveolar bone loss)






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






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






24. 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






25. Cervical 3rd






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






27. Tooth positioned more lingual






28. The permanent molars erupt posterior to the primary teeth and push them all mesially






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






30. Teeth are misaligned when biting together






31. Incisal 3rd






32. Starts around the mesial of the 1st molar






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






34. II (mal)occlusion






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






36. Mandibular molars and maxillary molars are even






37. Mesognathic profile






38. Maxillary anterior teeth stick out labially from tongue thrusting






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






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






41. What is not affected by occ trauma






42. Mand. retruded-one or more max. incisors retruded; max. laterals protruded-max centrals retruded; crowded max anterior teeth; deep overbite






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






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






45. Relationship of the teeth in opposite arches; static position






46. Max. incisors lingual to mand. incisors; incorrect horizontal overlap






47. 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






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






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






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