6
Q
describe aligner therapy in early 2000’s
A
- minor alignment
- limited correction of rotations
- no predictable vertical control
- clear aligners push
- clear aligners do not pull
7
Q
what force is applied to the crown in aligner therapy
A
- the line of action is at a distance from the center of resistance
- a moment of force is created by the force
8
Q
aligners alone are:

not enough
9
Q
the majority of treatments may require the use of:
A
- attachments
- elastics

- bite ramps
10
Q
what do attachments do
A
- correct rotations
- improve root movement
- anchorage
- extrusion
11
Q
what do elastics do
A
- class II mechanics
- class III mechanics
- increase anchorage
- correct midlines
12
Q
what do bite ramps do
A
- used to open the bite
- level de curve of spee by extruding and uprighting lower molars
- less proclination of lower incisors
