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






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

5. After periodontal sugery - mobility will ________






6. Max canine occludes with mand. canine and mand. 1st premolar.






7. Below occlusal plane






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






9. Maxillary overlap mandibular; whole arch






10. Tooth positioned more lingual






11. Starts around the mesial of the 1st molar






12. Mandible moves to the right or left






13. Any deviation from the ideal or normal occl. includes crowding - malpositioned or tipped teeth






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

16. Guidance for protrusive occ should be on the






17. Retrognathic profile






18. Contact between maxillary incisors does not line up with contact of mandibular incisors






19. Lateral mvmt results in contacct of all posterior teeth






20. ____ is not a sign of occl trauma






21. Vertical overlapping






22. Growth hormone imbalance that causes the mandible to grow faster than the maxilla(all teeth are in crossbite)






23. Cervical 3rd






24. Maximum touching of max and mand






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






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






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






28. Mb cusp of max 1st molar-buccal groove of mand 1st molar






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






30. Injury to the attachment apparatus (bone - PDL - and cementum) as a consequence of normal or excessive occ forces






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






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






33. Class III (mal)occlusion of permanent teeth






34. Normal contacts between max. and mand. teeth; momentary contacts






35. Maxillary - Mandibular - Facial






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






37. Excessive occ force with adequate bone support =






38. Mandibular molars and maxillary molars are even






39. 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






40. 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

42. Mesially - Labially






43. Spaces between two teeth






44. 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
