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. Maxillary - Mandibular - Facial






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






3. Class III (mal)occlusion of permanent teeth






4. 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






5. Above occlusal plane






6. Injury to the attachment apparatus (bone - PDL - and cementum) as a consequence of normal or excessive occ forces






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






8. Mesially - Labially






9. Tongue thrusting; thumb sucking - pacifiers






10. Most retruded position of the mandible in relation to the maxilla From which lateral mvmts of the jaw can be made






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






12. Crowns tipped lingually - roots tipped laterally






13. What is not affected by occ trauma






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






15. ____ is not a sign of occl trauma






16. Prognathic profile






17. Vibrational mvmt of a tooth under occ function






18. Introduced the concept of codestruction






19. 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






20. Anterior; no horizontal overlap






21. Retrognathic profile






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






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






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






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






26. Tongue thrust or thumb sucking can cause






27. Buck teeth are common and are considered






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






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






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






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






32. Curved alignment of the occlusal plane when looking from a posterior view(right to left)






33. Incisal 3rd






34. Vertical overlapping






35. Starts closer to the posterior of the 1st molar






36. 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






37. After periodontal sugery - mobility will ________






38. 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






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






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






41. Guidance for protrusive occ should be on the






42. Reshaping of the occ or incisal surfaces of teeth to create contacts btwn upper and lower dentition






43. 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






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






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






46. Occlusal guard =






47. Maxillary incisors are are lingual to mandibular incisors






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






49. Cusps of maxillary teeth directly over cusps of mandibular teeth






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