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






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






3. #10 & #23






4. Starts closer to premolars






5. Crowns tipped lingually - roots tipped laterally






6. 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






7. Maximum interlocking of cusp






8. Vibrational mvmt of a tooth under occ function






9. Mandible moves to the right or left






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






11. Middle 3rd






12. Anterior; no horizontal overlap






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






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






15. Class III (mal)occlusion of permanent teeth






16. The patient is constantly tightening the lower lip against the lower anterior teeth causing the the mandibular teeth to be pushed back into the mouth by this overdeveloped lower lip






17. Horizontal






18. Teeth are misaligned when biting together






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






20. During protrusive occ - ______ is considered undesirable






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






22. When no teeth are contacting on this side






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






24. Vertical overlapping






25. Laterally






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






27. 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






28. Posterior; no horizontal overlap






29. Prognathic profile; buccal groove of mand. 1st molar-mesial to mb cusp of max. 1st molar; distal of mand. canine mesial to mesial of max canine; tendency toward class III






30. After periodontal sugery - mobility will ________






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






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






33. Above occlusal plane






34. Functional occlusion






35. 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






36. Rotated or twisted; rotated mesial or distal






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






38. Relationship of teeth in which the incisal ridges or buccal cusp ridges of the maxillary anterior teeth extend facially to the incisal ridges/cusps of the mandibular teeth when the teeth are in centric occlusion relationship






39. Tooth positioned more facial






40. Below occlusal plane






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






42. High restoration - parafunctional habits - malpositioned tooth - periapical abcess - physical 'blow' - removable partial - ortho mvmt






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






44. Excessive occ force with adequate bone support =






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






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






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






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






49. Cervical 3rd






50. Does not result from brushing at all - but from traumatic lateral forces placed on the teeth as a result of a malocclusion or abnormal tongue activity. Root surface is exposed & can become carious
