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 positioned more lingual






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






3. Maxillary incisors are are lingual to mandibular incisors






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






5. Tooth extracted






6. Mandible moves to the right or left






7. Overlap of anterior teeth






8. Retrognathic profile






9. Symptom free dentition that 'survives' or 'adapts' to a deviated occl






10. Primary teeth set ___________________ for permanent






11. Rotated or twisted; rotated mesial or distal






12. Functional occlusion






13. Maxillary anterior teeth stick out labially from tongue thrusting






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






15. Anterior; no horizontal overlap






16. II (mal)occlusion






17. Vibrational mvmt of a tooth under occ function






18. #7 - 26 - 27






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






20. During protrusive occ - ______ is considered undesirable






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






22. Patients show evidence or signs and syptoms of occ disease






23. 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






24. 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






25. Relationship of the arches bone to bone;






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






27. Because the permanent premolars are narrower than the primary molars that they replace - this is what happens when the premolars erupt






28. Anterior teeth do not occlude - or remain open - while posterior teeth may have a normal occlusion






29. Later






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






31. Radiographically - the PDL space is wider at the coronal third of the root






32. Crowns tipped lingually - roots tipped laterally






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






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






35. Excessive occ force with adequate bone support =






36. Mesognathic profile






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






38. Incisal 3rd






39. 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






40. Maxillary overlap mandibular; whole arch






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






42. Maximum interlocking of cusp






43. What is not affected by occ trauma






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






45. Starts closer to premolars






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






47. Introduced the concept of codestruction






48. ____ is not a sign of occl trauma






49. Spaces between two teeth






50. Laterally
