Key Features

More Sustained Force Retention

TruGEN™ material provides better force retention and more efficient tooth movement than the leading aligner brand. With innovative Spark Clear Aligners you can provide your patients with comfort while also experiencing more efficient and pleasing results.*

Flexural Modulus (GPa)

The TruGEN material is the latest innovation in proprietary branded aligner material. There are two varieties, TruGEN and TruGEN XR™, that differ from each other in terms of flexibility. TruGEN XR is more rigid while TruGEN is more flexible. A higher flexural modulus value indicates a more rigid material.

Both TruGEN and TruGEN XR have .75mm (.030”) material thickness.

TruGEN™ Material Choices

TruGEN XR™

Spark™ Clear Aligners give doctors control and flexibility when choosing dental tray material options.

Doctors can now choose TruGEN™ and TruGEN XRTM for primary Spark 10 & 20 treatments and for refinements with all Spark Aligners cases*
TruGEN XR has the same advanced force retention, clarity, stain resistance, and material thickness that orthodontists love about TruGEN.*
Since TruGEN XR is slightly more rigid than TruGEN it is an ideal solution for finishing, refinements, and any clinical situation that would benefit from extra rigidity.

“The TruGEN aligner material is crystal clear and the software interface is amazing.”
—Dr. Stuart Frost*†

“The Spark attachment template material is outstanding. It peels off easily, doesn’t readily distort, and I’ve never found it to tear. As bonding attachments consumes more chairtime than almost all other aligner protocol, this adds to Spark's efficiency.”
—Dr. Vas Srinivasan*†

“The TruGEN material is very clear and seats well on the teeth.”
—Dr. Robert Gire*†

“Spark sets a new standard in clarity for aligners.”
—Dr. Jeffrey Heinz*†

“Our assistants were blown away by how user-friendly the attachment template is to use!”
