module 1 reinforcement Flashcards
which decade is craniofacial skeletal growth completed
upper jaw
-teens to twenties
vertical
- grown throughout our life (50s and later = answer)
growth
1) change
2) increase in size and number
development
1) increase in complexity
2) gaining cell specialization
growth pattern is the predicatable changes in body proportions over time
true
maxilla grows faster before mandible during adolescent growth (A)
because it is closer to the brain (B)
a) false, it is BEFORE adolescent growth that it is faster
b) this is true and related
cephalocaudal gradient
1) changes in body proportion over time
2) fetus head is 50%
3) at birth 25%
4 )adult 10-14%
—
1) maxilla grows faster than mandible before adolescence
maxilla
1) influenced more by growth at the cranial base of the brain
2) accelerates early on then plateaus
mandible
1) influenced more closely to the general body curve
2) accelerate, plateau, then growth at the pubertal spurt
monitoring
1) male and female
- pediatric growth charts
2) weight and standing height
3) predicts how a patient will grow
- and treat if they do not grow in a normal way
4) pubertal growth spurt is BEST time for mandible ortho treatment
craniometry
1) human growth measurements
anthropometry
1) living individual measurements
cephalometric radiology
1) used in ortho to check CVM
6 stages of cervical vertebral maturation
1) working out the timing of ortho treatment
- where are they in skeletal maturation phases
2) C2, C3, C4
- those have specific shapes in growth
- width, height, concavity
3) stage 3 is the best time
synchondroses
1) filled with cartilage
2) active, independent growth
3) capable of independent growth
4) not direct ossification
- deposition of bone on bone (aka intramembranous)
how does a long bone grow
1) growth plate present
2) grows in a layer of periosteum adjacent to bone surface
