Describe the growth chart with the 4 different curves on it.
What is the least accurate assessment of growth development?
Chonological age - birthday candles
Describe the growth patterns of the maxilla and mandible.
- Maxilla
- Intramembranous ossification
- Moves out from under cranium - downward and forward
- Mandible
- Endochondral and Intramembranous ossification
- Chin - downward & forward
- Condyle - upward & backward
- Ramus - grows away from chin
What is the primary growth of the cranium, when does most of it happen?
- The first few years
- Sutures & synchondroses
- Fontanelles
When are the first signs of tooth initiation show up?
6 weeks in utero
