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. Habitual - acquired - convenience - intercuspal & static






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






3. Vertical overlapping






4. When one tooth hits before all others when closing teeth together(may cause TMJ problems)






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






6. II (mal)occlusion






7. Occlusal guard =






8. Mvmt of the mandible in a direction anterior to centric occ






9. Below occlusal plane






10. Contact between maxillary incisors does not line up with contact of mandibular incisors






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






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






13. Individual teeth from each arch can be involved in ________________ malocclusion






14. Laterally






15. Measurement of horizontal overlap w/ probe






16. Maxillary overlap mandibular; whole arch






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






18. Anterior; no horizontal overlap






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






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






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






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






23. Crowns tipped lingually - roots tipped laterally






24. Middle 3rd






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






26. Mand. retruded-max. incisors protruded; deep overbite; excessive overjet - abnormal muscle function - short mandible - short upper lip






27. Abnormal contacts; occlusal habits - and neuroses






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






29. When no teeth are contacting on this side






30. Malocclusion cause excessive incisal or occlusal wear(attrition); teeth continue to erupt in order to occlude with teeth in the opposite arch & roots become exposed






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






32. Cervical 3rd






33. Incisal 3rd






34. Tooth positioned more lingual






35. Horizontal distance of anterior teeth in crossbite






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






37. Horizontal






38. Maximum touching of max and mand






39. Both sides






40. Primary teeth set ___________________ for permanent






41. Starts closer to premolars






42. Maxillary anterior teeth stick out labially from tongue thrusting






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






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






45. Excessive occ force with adequate bone support =






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






47. Overlap of anterior teeth






48. 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






49. Lateral mvmt results in contacct of all posterior teeth






50. #10 & #23
