The Latest Advancements in Clear Dental Aligner Material*

Designed for a high-tech smile transformation experience, our aligners are made with the latest dental aligner material available. Spark Aligners’ TruGEN is proven to perform better compared to the leading aligner brand with:

  • More sustained force retention
  • Better surface contact area with the tooth
  • Clearer, more comfortable, and stains less

Force retention is a key factor impacting aligner predictability.*

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 (.030in) material thickness.

Hear From Spark Providers

“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!”
