The Snodgrass is a fixed appliance that expands transversely followed by molar distalization. The Snodgrass appliance is most often used as a rapid palatal expander. In addition, it also offers the unique option of distalizing the molars following the lateral expansion phase. The distalization capability can be pre-activated at the laboratory if desired. The convertible caps on the lingual of the molar bands make additional adjustments easy.
