Functional Applicances Flashcards
(7 cards)
1
Q
Aim of functional applicances
A
- Eliminate abnormal perioral muscle function
- Facilitate dental arch development
- Correct occlusal relationships of maxilla and mandible
Perioral muscle function can affect natural muscle growth
2
Q
Period of use of functional appliances
A
From mixed dentition to permanent dentition
3
Q
Functional applicance classification
A
- Myotonic
- Myodynamic
4
Q
Myotonic appliances use
A
- Redistribute mastication force to dental arch
- Induce isometric muscle contraction through compressive stress and strain on muscles
5
Q
Myotonic activators
A
- Haupl-Andresen
- Monobloc
- Inclined plane plate
Monobloc and inclined plane plate modifications of Haupl-Andresen
6
Q
Myodynamic appliances use
A
- Restore balance between tongue and perioral muscles
- Induce isotonic muscle contraction resulting in abnormal and restrictive influences being eliminated
7
Q
Functional appliances are fabricated in
A
Working bite
Determines new position of mandible
