A unique feature of the SmartClip™ SL3 and Clarity™ SL Self-Ligating Appliance Systems is their ability to add a tandem archwire for more control during first- and second-order corrections.
Once in place, the tandem archwires provide complete rotational and angulation correction, as well as full vertical correction due to the vertical alignment of the two archwires. Using tandem archwires can often shorten the length of treatment. ( disclaimer
