What Do You Know About Palatal Expanders, And How Do They Work?

May 9, 20220

Palatal expanders are the orthodontic devices that help create more space in a child’s mouth by widening or expanding the roof of the mouth (palate) over time. The primary purpose of a palate expander is to broaden the narrow palates in children and correctly align the jaw and upper teeth. They can complete this treatment only when the jaw is still developing. Investing in a palatal expander at a young age is the most effective way to prevent crowded teeth, bad bites, and other misalignment issues. Each patient’s expanders are custom-made depending on their dental arch and palate size.

The dental expander devices are available in both fixed and removable versions. It consists of two sections that are screwed together in the middle. You merely turn the screw a minimal amount each day using a specific key to activate the device. It creates tension where the two palatal bones meet, forcing them to drift apart.

After achieving the expansion, we will leave the device in place for a few more months. We desire to allow new bones to develop in the gap and consolidate the development. According to an orthodontist specialist near me, you should wear a palate expander for 3 to 6 months.

What are the types of palatal expenders?

The common types of palate expanders are

Rapid Palatal Expander (RPE)

With the help of a rapid palatal expander, you can address narrow palates, crowding, and crossbites with a screw in the center. The appliance fits appropriately over a few back teeth in the upper jaw. You use a specific key to turn the screw a small amount each day to build tension between the two palatal bones to activate an RPE. According to a dentist who does palate expander for adults, the purpose is to enlarge the dental arch, widen the upper jaw or maxilla, and shift the teeth within the bone.

The jaw widens when the two palatal bones separate over time. After achieving the expansion they desire, most orthodontists leave the appliance in place for a few months to allow new bone to form. Palate growth treatment usually takes three to six months.

Implant-Supported Expansion

Mature adolescents generally require an Implant-supported mouth expander. Once the jaw is almost wholly developing, it will need heavier forces to widen the jaw and palate. It is an expansion treatment that consists of four miny implants that apply pressure directly to maxillary bone instead of the teeth.

Removable Palatal Expander

An orthodontist usually recommends a detachable expander when a patient simply requires minor jaw widening. These products resemble acrylic retainers, but they make them from chrome.

Surgically Assisted Palatal expansion

A wholly grown jaw is usual as a person reaches full adulthood (puberty). However, some jaws may not fully develop until they are between 21 and 25. A local orthodontist must surgically introduce an expander into the mid-palatal suture if this is the case (palate bone).
