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. Both sides






2. Lateral mvmt results in contacct of all posterior teeth






3. Vibrational mvmt of a tooth under occ function






4. Tongue thrusting; thumb sucking - pacifiers






5. Introduced the concept of codestruction






6. What is not affected by occ trauma






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






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






9. Crowns tipped lingually - roots tipped laterally






10. Maxillary-between canines and laterals - mandibular-between canines and 1st molars






11. II (mal)occlusion






12. Mandibular molars more distal than maxillary molars






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






14. Rotated or twisted; rotated mesial or distal






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






16. Habitual - acquired - convenience - intercuspal & static






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






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






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






20. Overlap of anterior teeth






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






22. A continuation of the spee of to extend through the condyle






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






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






25. 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






26. #10 & #23






27. Starts closer to premolars






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






29. Above occlusal plane






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






31. Cervical 3rd






32. Need tooth to tooth contact on both working and non working sides to func effectively






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






34. Maxillary anterior teeth stick out labially from tongue thrusting






35. Primary teeth set ___________________ for permanent






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






37. Tongue thrust or thumb sucking can cause






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






39. Tooth extracted






40. Guidance for protrusive occ should be on the






41. Maximum interlocking of cusp






42. Mesially - Labially






43. 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






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






45. 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






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






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






48. Curve of the occlusal plane; from anterior to posterior - increases with age






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






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