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. Survival of the dentition despite its deviation from a preconceived hypothetical normal






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






3. Maxillary - Mandibular - Facial






4. Above occlusal plane






5. After periodontal sugery - mobility will ________






6. Tooth positioned more lingual






7. #10 & #23






8. Primary teeth set ___________________ for permanent






9. Difference between primary and secondary occ trauma






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






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






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






13. 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






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






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






16. Anterior; no horizontal overlap






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






18. Vertical overlapping






19. Maximum touching of max and mand






20. Permits healing of the attachment apparatus by holding a tooth in a totally fixed position; allows the PDL to become narrower and the mobility to be reduced






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






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






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






24. Occlusal guard =






25. Vibrational mvmt of a tooth under occ function






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






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






28. Guidance for protrusive occ should be on the






29. Habitual - acquired - convenience - intercuspal & static






30. Abnormal contacts; occlusal habits - and neuroses






31. Slight buccal inclination of crown - lingual inclination of root






32. Introduced the concept of codestruction






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






34. Relationship of the arches bone to bone;






35. Crowns tipped lingually - roots tipped laterally






36. During protrusive occ - ______ is considered undesirable






37. Starts closer to the posterior of the 1st molar






38. What is not affected by occ trauma






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






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






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






43. Both sides






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






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






46. Relationship of teeth in which the incisal ridges or buccal cusp ridges of the maxillary anterior teeth extend facially to the incisal ridges/cusps of the mandibular teeth when the teeth are in centric occlusion relationship






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






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






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






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