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. During selective grinding - occlusion should be adjusted In what four relationships






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






3. Functional occlusion






4. 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






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






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






7. Starts around the mesial of the 1st molar






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






9. Vertical overlapping






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






11. Cervical 3rd






12. Crowns tipped lingually - roots tipped laterally






13. Excessive occ force with adequate bone support =






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






15. Mandibular molars more distal than maxillary molars






16. Retrognathic profile






17. Below occlusal plane






18. Teeth are misaligned when biting together






19. II (mal)occlusion






20. Abnormal contacts; occlusal habits - and neuroses






21. Occlusal guard =






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






23. When no teeth are contacting on this side






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






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






26. Maximum touching of max and mand






27. 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






28. Maxillary overlap mandibular; whole arch






29. Severe ging inflammation extending into CT attachment - loss of supporting alveolar bone - pregnancy - ortho mvmt - and surgical therapy - may all cause ______






30. Middle 3rd






31. Anterior; no horizontal overlap






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






33. Mesially - Labially






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






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






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






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






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






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






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






41. What is not affected by occ trauma






42. Incisal 3rd






43. 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






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






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






46. Most common cause is when the maxilla does not grow in proportion to the mandible






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






48. Both sides






49. Horizontal distance of anterior teeth in crossbite






50. Curve spee & wilson - 3-d - not proven
