Treatment overview

What are orthodontic expanders?

Orthodontic expanders, also called Rapid Maxillary Expanders (RME), are appliances used to treat a narrow upper jaw and crossbite. The appliance is custom-made for the patient and is activated using a small key.

Expansion is most useful while the upper jaw is still developing, which is why assessment at the right stage of growth matters.

Treatment advantages

Why choose orthodontic expander plates?

01

Minimal discomfort

RME treatment is often well tolerated and can be used in children from a relatively young age when indicated.

02

Early intervention

Correcting a narrow palate during growth can address the transverse jaw problem before later comprehensive treatment.

03

Highly effective

When used at the appropriate developmental stage, expansion can produce substantial correction of a narrow upper jaw.

The process

How does it work?

The expander gradually widens the upper jaw as the key is turned according to the activation schedule provided by the orthodontic team. The appliance remains in the mouth during the expansion phase.

This treatment takes advantage of the developing upper jaw before the two halves become more mature and resistant to expansion.

Individual suitability

Who are orthodontic expanders suitable for?

Expanders are commonly used for children with a narrow upper jaw or crossbite. The old Go Orthodontics treatment information identifies ages around 8–10 years as a common treatment period, with selected older patients potentially remaining suitable depending on skeletal maturity.

Because expansion is a specialised treatment, suitability is confirmed after an orthodontic assessment.
