The MemRx D is designed to increase arch length by moving posterior teeth distally. Anchorage is achieved by connecting the first bicuspids together via an anterior lingual arch. A Nance button may be used in addition to, or instead of, the anterior lingual arch if sufficient anterior teeth are not present to anchor the appliance.

Distalization of the molars is accomplished by compressing the Nickel Titanium coil spring with the Inman Power Component (I.P.C.). Using the special adjustment tool, the I.P.C. can be moved in increments ranging from 1 millimeter to several millimeters. depending on the needs of the particular patient. However, once the clinician has had experience with the I.P.C., several millimeters of spring compression can be placed into the appliance at the initial seating. (See back cover for proper adjustment of MemRx appliances)

The MemRx D appliances can be used in conjunction with any Straight Wire mechanics. Buccal tubes added to the molar bands will accept any .022 or .018 size arch wire.

The appliance consists of the following:

• Molar bands with straight wire tubes and lingual I.P.C.s.
• First bicuspid bands.
• A lingual wire soldered to the bicuspid bands.
• I.P.C.s placed on lingual.
• Nickel Titanium Open-Coil spring placed over the I.P.C. slotted wire.
• I.P.C.s soldered to lingual of bicuspid bands.
