Weinmann-Sicher theory (1947) stated what?
|
Sutural expansion was responsible for downward & forward translation of viscerocranium
Slide 3: four sutures |
Fronto-maxillary
Zygomatico-temporal Zygomatico-maxillary Pterygo-palatine |
|
|
What was the basis of JH Scott's cartilage theory?
|
Nasal cartilage continues to grow post-transplant.
Condylar cartilage does not. If it continues to grow then it is a growth center. |
|
|
|
Melvin Moss said what had absolutely nothing to do with growth?
What does? |
Cartilage
Soft tissues such as the brain, muscles of mast. and sinuses |
|
|
|
What are the (2) functional matrices of the Melvin Moss theory?
|
Periosteal matrix
Capsular matrix |
|
|
|
Which matrices act upon skeletal units directly, through resorption and deposition.
|
Periosteal matrices
|
|
|
|
Which matrices act upon functional cranial components indirectly?
(by altering the volume) |
Capsular matrices

Explain the Hunter-Enlow Growth Equivalent Theory
|
The face consists of horizontal and vertical equivalents
|
|
|
|
Ant cranial base
Maxilla and body of Mandible What do these make up? |
Horizontal Equivalent
|
|
|
|
According to Hunter-Enlow what causes malocclusion?
|
Max ≠ Mand growth
|
|
|
|
What four things are contiguous in the Growth Equivalent theory?
|
Mandible
Middle Face Upper Face Calvarium |
|
|
|
According to Growth Equivalent Theory, growth occurs where?
Four places |
Growth occurs at:
- sutures - periosteum - endosteum - synchondroses |
|
|
|
Growth is a combination of what two processes?
|
Complex remodeling
Translation |
|
|
|
Differentiate primary and secondary translation
|
Primary - change from within
Secondary - influenced by outside forces |
|
|
|
The complex pattern of deposition and resorption taking place in the growing mandible is called the __ _ Principle.
|
Expanding V
|
|
|
|
True or False: It is important to wait until the permanent dentition emerges to begin orthodontic treatment.
|
False. The longer you can milk Mom and Dad's insurance the better!
|
|
|
|
Overall potential for growth is primarily determined by __ factors
|
intrinsic
|
|
|
|
An individual's maximum growth potential is determined by what?
|
The environment.
|
|
|
What does this creepy picture demonstrate?
|
Different parts of the body develop at different rates/times.
|
|
|
|
Why do orthodontists ask girls about their periods?
|
Menarche signifies the pubertal growth spurt.
Time elapsed since menarche predicts remaining growth. |
|
|
|
When might you expect to see the sesamoid on a H/W radiograph of a female patient?
|
6 mos. post menarche
|
|
|
|
What skeletal indicator is used to determine when growth is nearly complete?
|
Closure of epiphyseal plates.
|
|
|
|
Height and weight measurements are important for adults, especially who?
|
Crusty old geezers, aka "the elderly"
|
|
|
|
How many stages of maturity are described as the CVM changes?
|
Five: CVM I, II, III, IV, V
|
|
|
|

What are they? |
Five:
A) Birth B) Puberty C) Adolescence D) Young Adult E) Adult |
