This appliance works in much the same way as the CD Distalizer. However, the design has been modified with the guide wires soldered to the first bicuspids (rather than using the vertical tube assembly to attach them to the bicuspids). Advantages: superior strength and added patient comfort -- attachments to the bicuspids are smooth and reduced in overall bulk. Although this design requires all four bands to be seated at once, this is typically not a problem. Appliance shown depicts the force module necessary to distalize #14 -- and use of the Gurin lock to maintain the already distalized #3. Note: Gurin Locks and open coil spring provide the necessary distalizing force to the molars.
