In brief: Exactly what it says

A palatal expander is an orthodontic appliances (usually fixed) designed to expand the upper jaw laterally (side to side).
Prior to the late teen years, the mid palatal suture has not fused yet. It can be split via orthopedic forces via the palatal expander to increase overall arch space to accomodate crowded teeth or coordinate a narrow upper arch to a normal lower arch.

A palatal expander is not done to accommodate crowding. The skeletal imbalance of narrow upper jaw to more wide lower jaw, yes, for crowding NO.
Dr. Donna Galante
The change in the arch form that results from a Palatal expander will definitely provide more room for the emerging adult teeth.

In brief: Palate expander

I'm not an orthodontist but i work with them daily and am very familiar with palate expanders.
It's an orthodontic appliance that is applied to the upper teeth and has a gear mechanism to allow for the slow, gradual daily expansion of the upper jaw in a growing child. It does not work in adults and will usually cause damage. It only works during growth, before the growth plates have fused.

A palatal expander is an orthodontic device used to expand or widen a narrow upper jaw.
It is generally used in a growing individual however there are applications in an adult however surgical assistance is necessary.

In brief: Mechanical device

Used non surgically in growing children, and surgically in adults after the 2 halves of the upper jaw bone have fused.
A mechanical appliance to apply pressure laterally to move the two halves of the upper jaw bone apart. In growing children this is a very common non-invasive treatment modality. I did palatal expansion for my own daughter.

There are many dozens of different ex panders, depending on the diagnostic criteria and the Orthodontist's preference. Ask your Orthodontist for individualized information.

In brief: Widener

Palate expansion takes on several forms.
In growing persons it is an orthopedic device that spread the 2 halves laterally=rapid maxillary expansion. In non growers, expansion can be done but it is dental expansion, only teeth move laterally. It should done for a crossbite only (or other esoterica).

In growers it is used rapidly, typically 1/2mm per day

In brief: Expansion

It is used to expand the palate in order to correct malocclusions such as cross bites where the top teeth overlap the bottom teeth on the tongue side instead of the cheek side.
Genetics and oral habits such as thumb sucking can cause these probs and bone malformations that need to be corrected prior to full growth. Best time for them is 8-10yrs old. See your dental provider for more care.

In brief: A device

that expands your upper jaw.
The goal is that your top jaw should be more in a 'U' shape and less in a 'V' shape. typically used on kids who have a more malleable jaw, but we have used VERY successfully even with patients in their early 20's
