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






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






3. II (mal)occlusion






4. What is not affected by occ trauma






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






6. Overlap of anterior teeth






7. Vertical overlapping






8. 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






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






10. #7 - 26 - 27






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






12. Class III (mal)occlusion of permanent teeth






13. Buck teeth are common and are considered






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






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






17. Mand. facial or lingual to max. - unitlateral or bilateral; incorrect horizontal overlap






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






19. Middle 3rd






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






21. 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






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






23. Relationship of the arches bone to bone;






24. Starts around the mesial of the 1st molar






25. Both sides






26. Horizontal






27. Mvmt of the mandible in a direction anterior to centric occ






28. When no teeth are contacting on this side






29. Tooth positioned more lingual






30. Horizontal distance of anterior teeth in crossbite






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






32. Laterally






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






34. Spaces between two teeth






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






36. Teeth are misaligned when biting together






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






38. Vibrational mvmt of a tooth under occ function






39. Occlusal guard =






40. 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






41. Guidance for protrusive occ should be on the






42. Below occlusal plane






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






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






45. 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






46. Prognathic profile






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






48. 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






49. Introduced the concept of codestruction






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