We tried a lot of plastics before deciding on the one we felt was best, and in the past we've used a copolyester which offered a number of advantages over other aligners.

Since August 2024, we have been using a brand new bio-compatible resin, TC85 from Tera Harz.

This resin makes it possible to manufacture SMA 4.0 aligners with shape memory. This offers a number of advantages

  • More resistant
  • More transparent
  • Thinner
  • More flexible
  • More precise
  • More hygienic

All this means greater comfort and faster results for you.
