A fixed appliance
for the distalization and derotation
of the upper first molars, the
Pendulum appliance eliminates
patient compliance concerns from
this treatment objective.
A large
Nance type acrylic button is
used in conjunction with wire
rests that are bonded to the
occlusal surface of the bicuspids
to provide anchorage.
Helical
springs of .032 TMA wire extend
from the distal portion
of the acrylic button and are
fit into lingual sheaths on the
first molar bands. The springs
are preactivated in the laboratory
and, once fit into the sheaths,
provide a continuous light pressure
for the desired molar distalization.
The design is similar to the
Pendex pictured below without
the expansion screw.

The
Jet™ appliances
all use a combination of
the same components, but are
constructed
differently to accomplish
a variety of goals.
For your information
and convenience, we have displayed
them here on our web site and
listed them on our prescriptions
as well.
The diagrams listed
below, illustrate the different
uses of these very effective,
family of appliances.
