ortho Flashcards
1-prognathic
2-retrognathic
3-proclined
4-retroclined
5-protrusive
6-retrusive
1- jaw is forward
2-jaw is back
3-teeth angled forawrd
4-teeth angled back
5-forward
6-back
1-class 1
2-class 1 malocclusion
3-class 2 malocclusion
4-class 2 division 1
5-class 2 division 2
6-subdivision
1-upper 1st molars are key to occlusion
mesio-buccal cusp of upper first molar occludes in buccal grove of lower first molar
2-normal relationship of molars, line of occlusion= incorrect bc of malposed teeth, rotations, etc.
3-lower molar positioned distally relative to upper molar, line of occlusion isnt specified
4-large overjet
5-normal overjet
6-molars are class 2 on one side only
1-class 3 malocclusion
2-skeletal class 1
3-skeletal class 2
4-skeletal class 3
5-growth of maxilla & mandible
1-lower molar mesially positioned relative to upper molar, line isnt specified
2-normal relation of maxilla & mandible
3-mandible distal to maxilla
- mandible retrognathic
- maxilla prognathic
- or combo of both
4-mandible mesial relative to maxilla
- mandible prognathic
- maxilla retrognathic
- or combo
5-translate downward & foward during growth
1-maxillar growth
2-serial cephs
3-maturation of oral function
4-maturation of oral function
1-closely follows neural growth curve—peaks earlier bc if the sutures dont close first then the mandible will keep growing
2-accurate indicator for cessation of growth
3-infantile swallow—active contraction of lips
- tongue tip brought forward into contact w/ lower lip
- posture at rest
- ends by year 1
4-sucking thumb/finger
- age 8 more than 60% have adult swallow
- persisiting habits & infantile swallow affect development—anterior open bites & narrowing of maxilla= common
1-perm teeth
2-perm anterior teeth
3-spacing between primary incisors
4-crowding
1-erup as resorption of overlaying primary teeth & bone occurs…resorption must happen to allow eruption
2-erupt lingually—especially upper laterals & lower anteriors
3-necessary to provide room for larger perm teeth
- –in maxilla= between primary lateral incisors & canines
- –in mandible= between primary canines & 1st primary molars
4-normal from age 7-8
—space from slight inc in width across canines, slight labial positioning of central & laterals
&&& space from primate space (mand. arch)
1-leeway space
2-ugly duckling stage
3-flush terminal plane
4-age 6
1-primary molars larger than their successors
1.5 mm for maxilla & 2.6 mm for mandible
2-flaring/spacing of upper anteriors due to poor position of upper canines—high incidence of canines being impacted
3-normal relationship of primary & perm molar
transitions to class 1 molars
—differential growth of maxilla & mandible
—mesial shift of molars into leeway space
4-first eruption of perm teeth
- –mandibular centrals
- –mandibular 1st molar
- –maxillary 1st molar
1-age 7
2-age 8
3-age 9-10
4-age 11
5-age 12
6-age 15
1-maxillar centrals
mandibular laterals
2-maxillary laterals
3-root formation of incisors & molars= complete
root resorption of primary canines & molars
root development of perm canines & PM—watch canine position
4-eruption of mand canines
mand 1st PM
max 1st PM
5-eruption of remaining perm teeth
- last teeth to erupt are max canines & mand 2nd PM
- –so higher chance of being impacted
6-roots of perm teeth complete…watch for 3rd molar position
1-ortho problems
2-skeletal class 2
3-skeletal class 3
4-pseudo class 3
1-sagittal (a/p) relationships
vertical relationships
transverse
arch length
2-retrognathic mandible & prognathic maxilla
3-maxillary retrognathic
mandibular prognathic
or maxilla/mandible prognathic
4-incisal interference at initial contact upon closure
-anterior functional shift of mandible to achieve posterior contact
1-long face syndrome
2-transverse
1-inc mandibular plane angle & inc anterior facial height
- chin rotates back & down
- anterior open bite
- class 2
2-unilateral r. posterior crossbite—functional shift
-skeletal asymmetry
class 1
class 1
class 2
class 1 malocclusion
class 2 malocclusion
full step class 2
end-on class 2
class 2 subdivision right
skeletal class 1
skeletal class 2
skeletal class 3
vertical problems
—deep bite
vertical problems
—open bite
long face syndrome ---corresponds w/ class 2
transverse
—unilateral right posterior crossbite
