This appliance is useful in correction of minor rotation and crowding up to 1.5 millimeters from cuspid to cuspid in the anteriors. The space necessary to correct this crowding is gained by judicious interproximal re-contouring in the anterior region only, as the appliance is not designed to gain any arch width or length.

Before fabricating the appliance, the lab will separate the rotated and crowded anteriors from the stone cast and will reset them in ideal alignment. A labial and lingual acrylic matrix of the newly positioned anterior teeth is formed on the active wires of the appliance. The appliance is then fabricated to this corrected anterior position and sent back to you for delivery. On the day of delivery, complete the necessary interproximal re-contouring, and then seat the appliance. NOTE: Do not activate the I.P.C. modules before cementation of the appliance.

Activate the I.P.C. / NiTi coils by using the specialized adjustment tool sent with the appliance. Place the slotted portion of the tool to engage the adjustment collar and push the tool and collar in the direction that will compress the NiTi coil spring. EXAMPLE: On the lingual I.P.C. you will push the tool and the collar distally towards the molars. On the labial I.P.C. you will push the tool and collar mesially towards the anteriors. (both are pictured at below right)

As this is a fixed, cemented appliance, the forces generated by activation of the I.P.C. / NiTi coil springs will immediately and consistently start aligning the malpositioned anterior teeth. Correction will be achieved in a short time. However, the patient should remain in the appliance for a period of time after alignment has been achieved for stability. A bonded retainer can be seated at a later time if the doctor or patient wishes.
