The Modified Spring Retainer is useful for correcting minor rotations of the upper anterior teeth. The teeth are set-up in the corrected position on the model. The appliance is then constructed. The dentist completes the necessary interproximal recontouring on the day of delivery. When in place, the resulting labial-lingual force will align the teeth.

The helical coil (in the labial wire portion), and the “mushroom” helical coil spring design of the active lingual component make this appliance very effective for quickly aligning the incisors. The appliance may also be used as a final positioning retainer, but is not recommended for closing spaces.NOTE: The Modified Spring Retainer will NOT gain arch width or length. Adequate space for alignment of the anteriors is essential.
