The
unique 3-Way Expander features
three independently expanding
sections in one housing-
for transverse as well as
sagittal anterior development.
Each section can be independently
activated. When an
equal amount of lateral development
is desired, turn the two
lateral sections at the same
time. If a differential amount of lateral development is needed, by turning
one of the lateral sections, the rest of the appliance will act as an anchorage
unit - making unilateral movement possible.
