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. Middle 3rd






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






3. Maxillary incisors are are lingual to mandibular incisors






4. II (mal)occlusion






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






6. Teeth are misaligned when biting together






7. Relationship of the arches bone to bone;






8. 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






9. Mandibular molars and maxillary molars are even






10. Maxillary - Mandibular - Facial






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






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






13. Mesognathic profile






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






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






16. 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






17. Crowns tipped lingually - roots tipped laterally






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






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






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






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






22. Overlap of anterior teeth






23. Maxillary overlap mandibular; whole arch






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






25. 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






26. Later






27. Functional occlusion






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






29. Horizontal distance of anterior teeth in crossbite






30. Widening of the PDL in areas under pressure results due to






31. Starts around the mesial of the 1st molar






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






33. Maximum touching of max and mand






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






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






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






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






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






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






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






41. ____ is not a sign of occl trauma






42. Above occlusal plane






43. Buck teeth are common and are considered






44. Excessive occ force with adequate bone support =






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






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






47. Introduced the concept of codestruction






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






49. Prognathic profile






50. Lateral mvmt results in contact btwn the max and mand canines
