Show Answers:

  1. when the maxillary and mandibular teeth come together in a fully closed position
    contact relationship
  2. if occlusion is off, it can affect what three thing?
    • musculature
    • neuromusculature
    • TMJ
  3. T/F occlusal disharmony can cause recession or cracks in the teeth.
    true giggity giggity!
  4. occlusal trauma of the teeth and periodontium can cause:
    bone loss
  5. irreversible occlusal trauma can lead to:
    tooth loss
  6. for checking normal occlusion, look at the ____ _______ and if they are missing, use the ________.
    • 1st molars
    • canines
  7. normal occlusion=________ occlusion
  8. the MB cusp of the maxillary first permanent molar occludes with the buccal groove of the mandibular first permanent molar. which classification is this?
    normal (ideal) occlusion
  9. T/F it is normal for normal occlusion to occur naturally.
    false! it is rare
  10. when would you want someone in centric occlusion (normal bite)?
    to determine classification
  11. the way you bite normally is called _________ occlusion
    habitual ("i bet you'll" occlude like that everyday!)
  12. Habitual occlusion ___________ forces of impact
  13. does tooth loss rearrange the occlusion? what else does it do?
    • it most certainly does!
    • cause a little of that what i like to call "drifting" to occur
  14. centric occlusion is also called _________ occlusion
  15. how do you measure the overjet?
    with a probe from the facial mandibular to the lingual of the maxillary incisor
  16. the natural HORIZONTAL overhang of the maxillary arch over the mandibular arch:
    overjet the what jet? the jet that flew over the horizon!
  17. T/F an overjet is equally distributed in males and females
    T - R - U - E what does it spell?? TRUE!
  18. normal amount of VERTICAL overlap allows for contact between the posterior teeth during mastication
    overbite me
  19. when that maxillary teeth come within the INCISAL third of the mandibular teeth:
    normal overbite
  20. T/F overbite is more common in females
  21. why does overbite and overjet tend to diminish with age?
    because of mandibular growth and later, attrition
  22. incisal edges of the maxillary teeth are within the MIDDLE third of the facial surfaces of the mandibular teeth
    moderate overbite
  23. incisal edges of the maxillary teeth are within the CERVICAL third of the facial of the mandibular teeth:
    severe overbite
  24. incisal edges of the mandibular teeth are in contact with the maxillary lingual gingival tissue, the overbite is considered:
    VERY severe
  25. what are the two types of contact areas:
    • proximal contacts
    • open contacts
  26. teeth that meet mesially and distally. stabilize the teeth:
    proximal contacts
  27. food impaction and gum troubles is caused from:
    open contacts
  28. all the spots where the contact points hit:
    contact stops
  29. what are the 3 areas of interdigitation during centric occlusion?
    • height of cusp contour
    • marginal ridges
    • central fossae
  30. tip of the cusp:
    height of contour
  31. marginal ridges are ________
  32. other cusp that occludes into the fossa
    central fossae
  33. cusps that function during centric occlusion:
    supporting cusps
  34. tooth to tooth wear:
  35. smooth surface that is flat on the incisal,occ, or buccal
    wear facets
  36. articulating paper is used to check ______ _______ after a restoration is placed:
    articulating paper
  37. if a restoration is too high, what are two things it can cause?
    • headache
    • toothache
  38. the end point of closure of the mandible
    centric relation
  39. is centric relation a natural position?
  40. for centric relation, the clinicial will ease the mandible into _______ position
  41. where one or two teeth hit too soon
    premature contacts
  42. too much sliding
    additional slide
  43. moving the mandible right and left until the canines on the side you are looking at are in a cusp to cusp relation
    lateral occlusion (excursion)
  44. during lateral occlusion, the side where the mandible has moved is called the ________ _______
    working side
  45. the side of the arch opposite to the working side during lateral occlusion is called the:
    balancing side
  46. in normal occlusion, the canine should be the only tooth functioning during the lateral occlusion, this is called:
    canine rise
  47. if all the opposite arch posterior teeth are sharing the occlusion (if there is no canine rise) during lateral occlusion, it is called:
    group function
  48. if teeth make contact on the opposite side during lateral occlusion, it is called:
    balance interference
  49. when all eight of the centrals and laterals are end to end during anterior protrusion:
    protrusive occlusion
  50. if some teeth don't touch during protrusive occlusion:
    occlusal disharmony
  51. when the mandible is at rest, it is in a ________ state
  52. when you fall asleep, your teeth should have ______ ______, the space between in relaxed rest
    freeway space
