Abstract
A U-shaped acrylic body is separated at its closed end and slideably connected by means of a turnbuckle to allow lateral adjustment, the acrylic body further having a palatal wire extending into the palatal area of the mouth, buccal wires emerging from the outer sides and extending in a rectangular construction parallel thereto, and cuspid guidance wires emerging perpendicularly from the outer sides. The palatal wire is separated at its approximate midpoint in the palatal area and slideably connected, such that when the appliance is positioned in the mouth adjacent the inner sides of the teeth the wearer can make periodic lateral adjustments.
