Comparison of Zendura FLX and Zendura A

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.

What do I need to Know Before Using Zendura FLX?

Zendura FLX is easy to handle

  • For clinicians and technicians familiar with commodity materials, we think you'll be pleased with the ease-of-use.
  • For clinicians and technicians currently using Zendura A, we think the increased flexibility of Zendura FLX will make many of your processes even easier.

Thermoforming

Zendura FLX requires different time and/or temperature settings than Zendura A. Check the Zendura FLX instructions for use for recommended settings.

Trimming

  • With Scissors: trimming should be easy and quick, no special technique required.
  • With burr or rotary cutter: consider reducing burr speed to reduce flash.

Finishing

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.
