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. #10 & #23






2. Horizontal distance of anterior teeth in crossbite






3. Below occlusal plane






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






5. Occlusal guard =






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






7. Mandibular molars and maxillary molars are even






8. Overlap of anterior teeth






9. Mesially - Labially






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






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






12. Both sides






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






14. Patient forces teeth together in centric occlusion on one side to get a more functional bite and has a crossbite on the other side(the midline of the maxillary anterior teeth does not line up with the midlineof the mandible






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






16. Vertical overlapping






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






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






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






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






21. Buck teeth are common and are considered






22. Transverse occlusal curvature; posterior teeth; medio-lateral postion (r-l)






23. Later






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






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






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






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






28. Maxillary overlap mandibular; whole arch






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






30. Mandibular molars more distal than maxillary molars






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






32. Above occlusal plane






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






34. 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






35. Lateral mvmt results in contacct of all posterior teeth






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






37. Maxillary incisors are are lingual to mandibular incisors






38. Posterior; no horizontal overlap






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






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






41. Functional occlusion






42. 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






43. Most common cause is when the maxilla does not grow in proportion to the mandible






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






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






46. Teeth are misaligned when biting together






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






48. The permanent molars erupt posterior to the primary teeth and push them all mesially






49. Abnormal contacts; occlusal habits - and neuroses






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