Aligner Material Makes Orthodontic Treatment More Predictable

Richard Gawel


Many clear aligner systems use off-the-shelf plastics but only Align Technology’s Invisalign system uses SmartTrack material, which is a proprietary material designed for the sole purpose of moving teeth, according to the company. Backed by decades of global research, patents, and successful cases, SmartTrack provides a greater than 75% improvement in the predictability of overall tooth movement compared to off-the-shelf, single-layer, 0.03-in material, Align says. The material also is four times more durable than generic materials, the company reports. It is designed to provide a better fit and comfort while being easier to use and remove than other clear aligners as well.
