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






2. Functional occlusion






3. Above occlusal plane






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






5. Middle 3rd






6. #7 - 26 - 27






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






8. Retrognathic profile






9. Difference between primary and secondary occ trauma






10. Teeth are misaligned when biting together






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






12. Anterior; no horizontal overlap






13. Crowns tipped lingually - roots tipped laterally






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






15. Horizontal distance of anterior teeth in crossbite






16. Introduced the concept of codestruction






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






18. Rotated or twisted; rotated mesial or distal






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






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






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






22. Occlusal guard =






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






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






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






26. 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






27. Later






28. 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






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






30. Primary teeth set ___________________ for permanent






31. #10 & #23






32. Buck teeth are common and are considered






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






34. Cervical 3rd






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






36. Max canine occludes with mand. canine and mand. 1st premolar.






37. Vertical overlapping






38. Mandible moves to the right or left






39. Overlap of anterior teeth






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






41. Abnormal contacts; occlusal habits - and neuroses






42. Mandibular molars and maxillary molars are even






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






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






45. Maximum touching of max and mand






46. Class III (mal)occlusion of permanent teeth






47. Tongue thrusting; thumb sucking - pacifiers






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






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






50. Maxillary incisors are are lingual to mandibular incisors
