Growth Predictions Flashcards
what are the best growth predictors
- mandibular plane angle
- Y axis
- Bjork studies
- normocephalic- dolychocephalic patients
how long does the mandibular plane angle stay stable
throughout life
what are bjork studies
patient tends to keep their growth pattern constant
when are female growth spurts
10-12 years old
when are male growth spurts
12-14 years old until 17
what should we consider about growth spurts
- timing of correction
- length of treatment
- to modify growth you must first experience growth
what is a frankl appliance
stimulation of periosteal growth by a;teration of the neuromuscular environment. stimulates periosteal pull and bone apposition
what is the rationale for intramembranous based on
functional martix
functional crossbite must be corrected at _____
a young age
what is class II correction
- true retrognatism - skeletal and genetic
- amount of dentoalveoalr compensations
- growth potential and growth prediction
what is growth prediction based off
age and family
what does head gear do
- slows down growth at the tuberosity level- growth site
- lets the mandible catch up
- then resume normal growth pattern
what are brachycephalic patients
class 2
what are dolycephalic patients
class 3
