Palatal expander. Animation showing a palatal expander, an orthodontic device used to widen the upper jaw, and braces. The expander fits into the roof of the mouth (palate) and is attached to the upper molars. Turning of the central screw applies a gentle force against the teeth to gradually push them apart. Once the palate has been expanded braces are often needed to realign the teeth. HD supplied with alpha, or for a flat version on a black background, see clip K003 3671. | |
