the upper and lower teeth can often be narrow or
constricted. This can cause teeth to become crowded
and is not as pleasing as a broad smile. An upper and
lower expander in children or braces in adults can be
used to correct this problem.
The pendulum appliance can be used to move the
upper molars backward in an effort to correct the
bite and make room for the front teeth.
Quad helix expanders increase the width of the
palate without the use of a traditional
screw-based expander. Quad helix expanders work
best in cases where minimal expansion is needed.
