Zendura™ FLX was designed as a premium aligner material. It is optimized to combine best-in-class patient comfort (and thus compliance) with pinpoint-accurate tooth movement over a one or two-week period. Zendura A (Classic Zendura) excels where either high initial movement force or extreme rigidity, such as for a retainer, is desired.
For longer-term usage - as in post-treatment retainers - and for special situations (e.g. heavy bruxers) the remarkable overall toughness of Zendura A will be beneficial.

Zendura FLX is easy to handle
Zendura FLX requires different time and/or temperature settings than Zendura A. Check the Zendura FLX instructions for use for recommended settings.
In our testing, we see less flash during trimming, so finishing should be easy. As with trimming, consider using a finishing tool at either lower speed or lower abrasion than used for commodity materials.
