  1. starting point, malocclusions due to dental malalignments
    Angle's classification of malocclusion
  2. Angle's classification of malocclusion does not describe normal or ______ occlusion, only malocclusion of the _______ and _______
    • ideal
    • molars
    • canines
  3. is angle's of classification ideal?
  4. lateral and protrusive are or are not addressed in the angles of classification?
    NOT addressed
  5. is primary or mixed dentition addressed in angles of classification?
    NO! only for 32 permanent teeth
  6. MB cusp of max 1st molar occludes with MB groove of mandibular 1st molar but with crowding of anterior teeth
    class I malocclusion (neutroclusion)
  7. max permanent canine occludes with distal half of the mandibular canine and mesial half of mandibular 1st molar
    class I malocclusion (neutroclusion)
  8. which class are buck teeth?
    class II malocclusion (distoclusion)
  9. the term for normal facial profile
    mesognathic (class I)
  10. which class includes overbite, open bite, cross-bite and end-to-end bite?
    class I malocclusion (neutroclusion)
  11. T/F class I malocclusion can be protrusive or retrusive discrepancies
  12. MB cusp of max 1st molar mesial to MB groove of mand 1st molar
    class II maloclusion (distoclusion)
  13. max permanent canine occludes with distal half of mandibular canine and mesial half of mandibular 1st premolar
    class I malocclusion (neutroclusion)
  14. mesial surface of max canine is mesial to the distal surface of the mandibular canine by at least the width of a premolar
    class II (distoclusion)
  15. which class has two subgroups and what are they?
    • class II malocclusion (distoclusion)
    • division I
    • division II
  16. what are the two subgroups, division I and II based on?
    position of the anteriors, shape of the palate, and resulting facial profile
  17. class II malocclusion division I in the permanent dentition, the max anteriors ________ facially from the mandibular incisors that are _________
    • protrude
    • retruded
  18. class II malocclusion division II the mandible is __________ and one or more max incisors are ________(laterals can be labially tilted)
    • retruded
    • retruded
  19. retrognathic is class:
    class II malocclusion (distoclusion)
  20. class III malocclusion is:
  21. MB cusp of max 1st molar occludes distally to the MB groove of the mand 1st molar:
    class III malocclusion (mesioclusion)
  22. distal surface of mand canine is mesial to the mesial surface of the max canine by at least the width of a premolar
    mand incisors in crossbite
    class III malocclusion (mesioclusion)
  23. what is the facial profile of class III malocclusion?
  24. asymmetrical cases of malocclusion are called:
  25. combinations of classes and divisions is:
    subdivisions of malocclusion
  26. in primary dentition, ideal molar relationship in the primary dentition when in centric occlusion is called:
    terminal plane
  27. T/F primary dentition canine relationship is the same as the permanent dentition
    true mudda trucka
  28. movements of the mandible that are not within the normal range of motion associated with mastication, speech, or respiratory movements
    parafunctional habits
  29. name four parafunctional habits
    • clenching
    • bruxism
    • abfraction
    • thumb sucking
  30. the parafunctional habits of clenching and bruxism often occur when someone is _________
  31. is it possible to retrain yourself to stay away from parafunctional habits?
  32. someone with a clenching or bruxism habit will most likely have large _________ muscles
  33. how are parafunctional habits treated?
    with an appliance
  34. what are some skeletal considerations?
    • jaw too big
    • too small
    • crowded teeth
  35. protruding, retruding chin, excessive gingiva, inability to achieve resting lip closure, and tmd are examples of common problems of ________ ________
    skeletal considerations
  36. which 2 classes are horizontal malocclusions?
    • class II
    • class III
  37. vertical malocclusions are (2):
    • open bite
    • overbite
  38. transverse malocclusions are:
  39. myofunctional is:
    incorrect lip resting position
