Skeletal expander

Skeletal expander

The skeletal expander (Hyrax, Rapid Palatal Expander, Banded Expander) is a very important part of orthodontic treatment. The expander helps increase the growth, thus widening the upper arch. It is used to carefully broaden the upper jaw by exerting lateral pressure on the two halves of the maxilla (upper jaw) in patients with a narrow upper jaw. If done properly, bone grows in the middle and a once-constricted maxilla can attain proper width to improve the bite. Ex­panding the maxilla may also help to create space for eruption of permanent teeth. This device can correct skeletal/dental problems that if left untreated, would require jaw surgery to correct later in life.
