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. Cervical 3rd






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






3. Abnormal contacts; occlusal habits - and neuroses






4. Mesially - Labially






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






6. Horizontal distance of anterior teeth in crossbite






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






8. 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






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






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






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






12. Mandibular molars more distal than maxillary molars






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






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






15. Middle 3rd






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






17. Introduced the concept of codestruction






18. Congenitally missing teeth - Impacted teeth & size and shape of muscle and bone






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






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






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






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






23. Incisal 3rd






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






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






26. Both sides






27. 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






28. Functional occlusion






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






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






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






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






33. Tooth extracted






34. Difference between primary and secondary occ trauma






35. Anterior; no horizontal overlap






36. Mesognathic profile






37. Excessive deposition of cementum around the apex - due to excessive occlusal forces






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






39. Maximum interlocking of cusp






40. Buck teeth are common and are considered






41. #7 - 26 - 27






42. Occlusal forces will accelerate the rate of perio destruction and result in CT attachment loss in the presence of preexisting inflammation






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






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






45. ____ is not a sign of occl trauma






46. Maximum touching of max and mand






47. Habitual - acquired - convenience - intercuspal & static






48. 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






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






50. Tooth positioned more lingual
