Here's something we can whole-heartedly endorse (and get financial compensation for): the ClearCorrect Trimming Kit.
For $90, the kit includes all the supplies you need to make your own replacement aligners in your office: 10 plastic sheets, a steel wheel saw, crown & bridge scissors, and 10 abrasive buff polishers.
Our kits have always included .030" sheets of Biocryl™ plastic. It works great. In fact, it's one of the best materials available for making aligners with a vacuum-former (the most common type of thermoforming machine in dental offices).
We've never talked much about the material we use ourselves here at ClearCorrect, and we've never offered it for sale. This is partly because it wasn't packaged for individual sale, and partly because it requires a more advanced pressure-forming machine such as the BioSTAR, MiniSTAR, Drufomat, or Drufosmart.
Today we can reveal that the material ClearCorrect uses to make our aligners (and retainers) is called Zendura®. It's an advanced polymer that was developed by Bay Materials specifically to balance the properties needed for clear aligners: strength, ductility, chemical resistance, clarity, and stress relaxation resistance. It's significantly more crack-resistant and stain-resistant than traditional PETG-based plastics. We believe that this is the most effective material ever developed for making clear aligners.
We're not offering Zendura for sale just yet, but we do have a limited supply of individually foil-wrapped samples available. If you have a pressure-forming machine, let us know when you order a Trimming Kit, and we'll include a free "sneak-peek" sample of this advanced material while supplies last. We'd love to hear how it works in your office.
