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. Hereditary - Tongue - Intercuspation of teeth - Alignment of previously erupted teeth affects alignment of successive teeth






2. Deciduous molars and canines are wider than permanent premolars and canines; space saved during mesial drift of permanent molars






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






4. Relationship of the arches bone to bone;






5. II (mal)occlusion






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






7. Starts closer to premolars






8. What is not affected by occ trauma






9. Teeth are misaligned when biting together






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






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






12. Does not result from brushing at all - but from traumatic lateral forces placed on the teeth as a result of a malocclusion or abnormal tongue activity. Root surface is exposed & can become carious






13. Incisal 3rd






14. Class III (mal)occlusion of permanent teeth






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






16. Difference between primary and secondary occ trauma






17. Habitual - acquired - convenience - intercuspal & static






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






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






20. 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






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






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






23. Posterior; no horizontal overlap






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






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






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






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






28. Vertical






29. Horizontal






30. Below occlusal plane






31. Anterior; no horizontal overlap






32. Occlusal guard =






33. Mandibular molars more distal than maxillary molars






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






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






36. Tooth extracted






37. Tongue thrusting; thumb sucking - pacifiers






38. Functional occlusion






39. Above occlusal plane






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






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






42. ____ is not a sign of occl trauma






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






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






45. Overlap of anterior teeth






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






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






48. Starts around the mesial of the 1st molar






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






50. Laterally
