Rapid maxillary expansion (RME) is a type of orthodontic treatment that involves widening the upper jaw to correct problems such as crowded teeth, crossbites, and breathing issues. The goal of RME is to create more space in the upper jaw, which can improve the overall function and appearance of the mouth.

During RME, a device called a palatal expander is placed in the mouth and attached to the upper molars. The expander is then gradually widened over a period of several weeks to several months, using a special key that is provided by the orthodontist. As the expander is widened, it applies gentle pressure to the upper jaw, gradually separating the bones and creating more space.

RME is typically performed on children and adolescents, as the bones of the upper jaw are still growing and can be more easily manipulated. However, in some cases, adults may also benefit from RME.

The benefits of RME include improved breathing, reduced risk of sleep apnea, and a more balanced facial appearance. It can also make it easier to clean the teeth and prevent dental issues such as tooth decay and gum disease.

Overall, RME is a safe and effective form of orthodontic treatment for correcting certain types of dental and breathing issues. It’s important to consult with a qualified orthodontist to determine if RME is the right choice for your individual needs.
