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. Vibrational mvmt of a tooth under occ function






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






3. Patient forces teeth together in centric occlusion on one side to get a more functional bite and has a crossbite on the other side(the midline of the maxillary anterior teeth does not line up with the midlineof the mandible






4. Middle 3rd






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






6. ____ is not a sign of occl trauma






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






8. Vertical






9. #7 - 26 - 27






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






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






12. Buck teeth are common and are considered






13. 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






14. Laterally






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






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






17. Cervical 3rd






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






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






20. If the mandible moves to the left - the mvmt is known as a left working movement






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






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






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






24. Radiographically - the PDL space is wider at the coronal third of the root






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






26. Horizontal distance of anterior teeth in crossbite






27. Maxillary - Mandibular - Facial






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






29. Maxillary anterior teeth stick out labially from tongue thrusting






30. Mand. facial or lingual to max. - unitlateral or bilateral; incorrect horizontal overlap






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






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






33. Maxillary incisors are are lingual to mandibular incisors






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






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






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






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






38. Normal contacts between max. and mand. teeth; momentary contacts






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






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






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






42. Vertical overlapping






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






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






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






46. Horizontal






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






48. Anterior; no horizontal overlap






49. Mesially - Labially






50. Retrognathic profile
