What is a rapid palatal expander?
A rapid palatal expander, or RPE, is a type of orthodontic appliance that is used to widen the two halves of the top jaw, also known as the palate or maxilla.
Why is a rapid palatal expander used during initial orthodontic treatment?
The main advantage of using a rapid palatal expander during phase 1 orthodontic treatment is that it helps create enough room for permanent teeth. This ensures that the upper arch is not crowded, which can lead to crooked teeth.
How does a rapid palatal expander work?
A rapid palatal expander is cemented onto the back upper teeth and is激活 (turn) periodically to exert gentle pressure on the midline suture, separating the maxilla.
When is a rapid palatal expander needed during orthodontic treatment?
Rapid palatal expanders are generally used for patients who have a narrow upper jaw, overcrowding of the teeth, or a crossbite.
Are there different types of palate expanders?
Yes, there are different types of palate expanders, including removable, rapid, surgically assisted, and implant-supported expanders.
Can adults use a rapid palatal expander?
The use of a standard palate expander is usually not recommended for adults because most growth is finished by late adolescence or early twenties. However, a mini-screw assisted rapid palatal expansion (MARPE) can be an option for adults in their early twenties.
