The MemRx ED is for lateral development of either arch and distalizing molars. It is an especially effective choice when used  to treat crowded arches that lack sufficient anterior/posterior length. Lateral development is achieved by the use of the Memory Expansion Screw. Proper AP is achieved by distalizing the molars via the NiTi Open Coil Springs which are activated by the Inman Power Component.

Once the appliance is cemented into the mouth, the screw may be adjusted 5-6 turns immediately. This will load the internal NiTi Open Coil Springs. Expansion is expressed in a gentle, more consistent manner than traditional RPE screws.

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 seven 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.
