16
Q

Profile analysis is difficult for….

A

very young children (younger than 6)

Class 3

when vertical problems are present

(profile analysis can be done… but it just needs to be done carefully)

17
Q

True or False?

Mandible is easier to grow than Maxilla

A

False

Maxilla is easier because mandible has condyles so modification can be difficult

18
Q

Possibilities for growth modification

A

Maxilla/mandible: maxilla is easier

Anteroposterior

Vertical: hardest to modify (but longest acting growth)

Transverse: 1st dimension to stop growing (that is why we usually correct posterior crow bite & Maxillary constrictions early)

19
Q

Types of growth modification

A
  1. Ultimate size changes (stimulation/retardation)
  2. Timing changes (acceleration/deceleration)
  3. Redirection (ap to vertical or vertical to ap_
20
Q

What do you need to do to get a successful growth modification?

A

must control all planes of space

interaction between the vertical and AP

21
Q

For class II maxillary protrusion, the best treatment options are:

A

Headgear (favored): force on maxilla, mandible grows

Functional appliances

22
Q

For class II mandibular retrusion, the best treatment options are:

A

Functional appliance (favored): best choice to put mandible forward

Headgear

23
Q

For Class III maxillary retrusion, the best treatment options are:

A

Face mask: best choice for max retrusion (pull forward)

functional appliances

24
Q

For class III mandibular protrusion, the best treatment options are:

A

Functional appliances

Chin cup: very minimal success, changes do not last

25
Q

What can you do to modify transverse growth?

A

opening of midpalatal suture: RPE for near and post-adolsecent

lingual arch type in primary and mixed dentitions: pre-adolescents

26
Q

True or False?

Early mixed dentition is no benefit to ultimate growth over late mixed dentition

A

True

If you do it too early…. you might end up doing 2 separate treatments..

27
Q

Is early transverse treatment beneficial?

A

Skeletal and dental changes can be made and maintained.

The changes can affect the unerupted teeth.

28
Q

When is early treatment justified?

A
  1. Esthetics or trauma reduction (class 2)
  2. Class 3’s - True max deficiency (can be corrected with max protraction)
  3. Posterior crossbites: with functional shifts and arch length shortages
