Understanding Maxillary Skeletal Expanders

A maxillary skeletal expander (MSE) is a type of orthodontic appliance that is used to widen the upper jaw. It is a non-surgical procedure that can be used to treat a variety of dental problems, including:

Narrow upper jaw
Crowded teeth
Posterior open bite
Midline deviation

MSEs work by applying pressure to the bones of the upper jaw. This pressure causes the bones to slowly widen, which creates more space for the teeth. MSEs are typically worn for 4-6 months, but the exact duration of treatment will vary depending on the individual patient’s needs.

There are two main types of MSEs:

Miniscrew-assisted MSEs: These MSEs use small titanium screws that are placed in the bone of the upper jaw. The screws provide anchorage for the expander, which allows for more controlled and gradual expansion.
Traditional MSEs: Traditional MSEs do not use screws. Instead, they rely on the teeth to provide anchorage for the expander. This type of MSE is typically used in younger patients, whose teeth are still growing.

MSEs are generally well-tolerated by patients. However, some side effects may occur, including:

Difficulty speaking
Increased salivation

These side effects are usually mild and go away on their own. However, if you experience any severe side effects, you should contact your orthodontist immediately.

If you are considering MSE treatment, it is important to talk to your orthodontist about the risks and benefits of this procedure. They can help you decide if MSE is the right treatment for you.

Here is some additional information about MSEs:

MSEs are typically used in children and adolescents, but they can also be used in adults.
MSE treatment is usually covered by insurance.
There are no special dietary restrictions during MSE treatment.
After MSE treatment, you may need to wear retainers to maintain the expansion.

Here are some questions you may want to ask your orthodontist about MSEs:

What are the risks and benefits of MSE treatment?
How long will I need to wear the expander?
What are the chances of side effects?
What will my teeth look like after treatment?
How much will MSE treatment cost?


MSEs are a safe and effective way to widen the upper jaw. If you are considering MSE treatment, talk to your orthodontist to learn more about this procedure and whether it is right for you. If you are in Sydney, you can book a Free Consult with us at any of our 5 locations.
