Each patient has an individual treatment plan that may or may not involve the use of some type of expansion or distallizing appliance.  These are some examples of the types of orthodontic appliances Dr. Mehan uses:

RAPID PALATE EXPANDER

(The design may vary for each patient.)

Used to widen the upper jaw.

DISTALLIZER

A Rapid Palatal Expander that also moves the 6 year molars back.
