The Sagittal can be constructed for wear on either the upper or lower dentition, and utilizes from one to three (usually two side) screws to lengthen the arches. The acrylic makes anterior contact in the cuspid area and posterior contact with bite pads. The cuts are distal to the cuspids, and create arch length when turned.

Working from a single basic design, the Sagittal may take various forms depending on the prescribed treatment. Five basic types are explained in our Ortho Handbook.
