starting point, malocclusions due to dental malalignments
Angle's classification of malocclusion
-
Angle's classification of malocclusion does not describe normal or ______ occlusion, only malocclusion of the _______ and _______
-
is angle's of classification ideal?
no!
-
lateral and protrusive are or are not addressed in the angles of classification?
NOT addressed
-
is primary or mixed dentition addressed in angles of classification?
NO! only for 32 permanent teeth
-
MB cusp of max 1st molar occludes with MB groove of mandibular 1st molar but with crowding of anterior teeth
class I malocclusion (neutroclusion)
-
max permanent canine occludes with distal half of the mandibular canine and mesial half of mandibular 1st molar
class I malocclusion (neutroclusion)
-
which class are buck teeth?
class II malocclusion (distoclusion)
-
the term for normal facial profile
mesognathic (class I)
-
which class includes overbite, open bite, cross-bite and end-to-end bite?
class I malocclusion (neutroclusion)
-
T/F class I malocclusion can be protrusive or retrusive discrepancies
true
-
MB cusp of max 1st molar mesial to MB groove of mand 1st molar
class II maloclusion (distoclusion)
-
max permanent canine occludes with distal half of mandibular canine and mesial half of mandibular 1st premolar
class I malocclusion (neutroclusion)
-
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)
-
which class has two subgroups and what are they?
- class II malocclusion (distoclusion)
- division I
- division II
-
what are the two subgroups, division I and II based on?
position of the anteriors, shape of the palate, and resulting facial profile
-
class II malocclusion division I in the permanent dentition, the max anteriors ________ facially from the mandibular incisors that are _________
-
class II malocclusion division II the mandible is __________ and one or more max incisors are ________(laterals can be labially tilted)
-
retrognathic is class:
class II malocclusion (distoclusion)
-
class III malocclusion is:
mesioclusion
-
MB cusp of max 1st molar occludes distally to the MB groove of the mand 1st molar:
class III malocclusion (mesioclusion)
-
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)
-
what is the facial profile of class III malocclusion?
prognathic
-
asymmetrical cases of malocclusion are called:
subdivisions
-
combinations of classes and divisions is:
subdivisions of malocclusion
-
in primary dentition, ideal molar relationship in the primary dentition when in centric occlusion is called:
terminal plane
-
T/F primary dentition canine relationship is the same as the permanent dentition
true mudda trucka
-
movements of the mandible that are not within the normal range of motion associated with mastication, speech, or respiratory movements
parafunctional habits
-
name four parafunctional habits
- clenching
- bruxism

is it possible to retrain yourself to stay away from parafunctional habits?
aaaaaaaaabsolutely!
-
someone with a clenching or bruxism habit will most likely have large _________ muscles
masseter
-
how are parafunctional habits treated?
with an appliance
-
what are some skeletal considerations?
- jaw too big
- too small
- crowded teeth
-
protruding, retruding chin, excessive gingiva, inability to achieve resting lip closure, and tmd are examples of common problems of ________ ________
skeletal considerations
-
which 2 classes are horizontal malocclusions?
-
vertical malocclusions are (2):

transverse malocclusions are:
crossbite
-
myofunctional is:
