The 3-Screw Sagittal Appliance combines a removable, sectional acrylic plate with three genuine orthodontic screw assemblies and stainless-steel wire components, including a labial bow across the front teeth.
Its defining feature is the three-screw layout: one central transverse screw arranged crosswise and two lateral sagittal screws arranged lengthwise, one on each side. This layout is used in both the upper and lower versions.
The lower version has a horseshoe-shaped acrylic base. Choose an appliance for the upper or lower jaw, or select Upper & Lower Jaw to receive two separate appliances, each with its own three-screw construction.
