This popular molar distalizer can be used on either arch and can also be used in a unilateral or bilateral configuration. The anterior portion typically attaches to the first bicuspid bands with a Nance Button -- and often with an additional lingual wire for anchorage. Vertical tubes on the buccal aspect of these bicuspid bands accept the .032 guide wires that run back through the horizontal tubes on the molar bands. Gurin Locks and open coil springs are placed to provide the necessary distalizing force to the molars.

Adjustments are made approximately every 3-4 weeks. Vertical tubes allow it to be placed segmentally, by first cementing the anterior segment, and then placing the molar bands (with .032 guide wires inserted in the tubes) as individual units. The appliance shown here is a depiction of the force module needed to distalize #14 -- and also of the use of the Gurin Lock to maintain the already distalized #3. Note: When selecting this appliance, please provide the lab with detailed instructions.
