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. Maxillary - Mandibular - Facial






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






3. Laterally






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






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






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






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






8. Max. incisors lingual to mand. incisors; incorrect horizontal overlap






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






10. Selective grinding should always be completed after ______ has been controlled






11. Maxillary anterior teeth stick out labially from tongue thrusting






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






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






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






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






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






17. Mandibular molars and maxillary molars are even






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






19. Deciduous molars and canines are wider than permanent premolars and canines; space saved during mesial drift of permanent molars






20. Reshaping of the occ or incisal surfaces of teeth to create contacts btwn upper and lower dentition






21. Relationship of the teeth in which the incisal ridges of the maxillary anterior teeth extend below the incisal edges of the mandibular anterior teeth when the teeth are placed in a centric occlusal relationship






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






23. Occlusal guard =






24. The way you normally bite your teeth together when not chewing






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






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






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. Tooth positioned more facial






29. Primary teeth set ___________________ for permanent






30. Retrognathic profile






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






32. What is not affected by occ trauma






33. Vertical overlapping






34. After periodontal sugery - mobility will ________






35. Horizontal






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






37. Anterior; no horizontal overlap






38. Rotated or twisted; rotated mesial or distal






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






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






41. Mandibular molars more distal than maxillary molars






42. Tooth extracted






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






44. Prognathic profile






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






46. Tooth positioned more lingual






47. A tooth that occludes with an opposing tooth before full closure is achieved in centric occlusion






48. Mesially - Labially






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






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