The Rapid Palatal Expander is an orthodontic device that functions to create a wider space in the upper jaw. This device is typically used when the upper jaw is too narrow for the lower jaw or when the upper teeth are crowded or blocked out of the dental arch.
When patients are young and still growing, their connective tissue between the left and right halves of their upper jaw is very responsive to expansion. The expander begins to work by simply activating it by turning a screw in the center, with a special key we provide. Gradual outward pressure is then placed on the left and right halves of the upper jaw. This pressure encourages a large amount of bone to grow between the right and left halves of the jaw, resulting in an increased width.
