3 - Growth Predictions Flashcards
(30 cards)
What are the best growth predictors?
- Mandibular plane angle
- Y axis
- Bjork studies
- Normocephalic-dolichocephalic patients
This plan tends to stay stable throughout life
Mandibular plane angle
This is when patients tend to keep their growth pattern constant
Bjork studies
Mesiocephalic =
Proportions of face as expected
This is when the length of face is longer compared to width
Dolichocephalic
what is another word for mesiocephalic?
normocephalic
This is when height = width, square face
Brachiocephalic
This increases maxillary length
Class III
This increase mandibular length or reposition mandible to correct malocclusion
Class II
What are the best times to correct malocclusions for girls?
9-11.5
What are the best times to correct malocclusions for boys?
10.5-14
When do females get growth spurts?
10-12
When do males get growth spurts?
12-14
In order to modify growth, you must first experience ____
Growth
This appliance gives stimulation of periosteal growth by alteration of the neuromuscular environment
Frankl appliances
This appliance will stimulate periosteal pull and bone apposition
Frankl appliance
Frankl appliance is associated with what growth?
Intramembranous
Are Frankl appliances a tooth borne appliance?
No
This modifies growth at Midpalatal suture above teeth to widen maxilla
Maxillary expansion appliance
A maxillary expansion appliance will give you up to how much expansion?
6mm
If the maxilla is not wide enough, what appliance would you use?
Maxillary expansion appliance
When does a functional crossbite must be corrected?
Young age
Maxillary expansion appliance is associated with what growth?
Sutural growth
You get sutural growth with what appliance?
Maxillary expansion appliance
