Rapid
Palatal Expander (RPE)
This appliance is typically used to widen
the upper jaw (maxilla) of a younger patient. It is attached
to the teeth, therefore not removable by the patient. The
orthodontist determines the frequency and quantity of the
turns, which are done by the parents at home.
Fixed
Lower Expander (FLE)
This appliance is used to broaden the lower
teeth. It is attached to the teeth, therefore not removable
by the patient. The orthodontist determines the frequency
and quantity of the turns, which are done by the parents
at home.
Pendulum
Appliance
The Pendulum appliance is custom made
to the upper jaw. It is used to move the upper molars backwards,
similar to the effects of headgear. It allows the orthodontist
to correct the upper molar position and gain arch length,
helping avoid permanent tooth extractions. It is not removable
by the patient, and is typically worn for 4-6 months.
T-Rex
Appliance
This appliance is a combination of the Pendulum
and the Rapid Palatal Expander. It has the ability to widen
the upper jaw, and move the upper molars backwards. It allows
the orthodontist to gain room in both the transverse (width)
and anterior-posterior (front-back) dimensions. This appliance
is not removable by the patient, and is typically worn for
4-8 months.
Herbst
Appliances
This appliance is attached to both the upper
and lower teeth. It is used for correcting the relationship
of the upper jaw to the lower jaw. It is particularly useful
for lower jaw asymmetry and when the lower jaw is significantly
positioned backwards. It provides the patient with an “unlocked” opportunity
for lower jaw growth as well as a substantial headgear effect
to the upper molars. It is not removable by the patient and
is typically worn for 12-18 months.
