AirFlex™ Aligners
The only FDA-cleared aligner for 12 hours of continuous daily wear time.*
AirFlex is designed for effortless compliance and predictability. Utilizing the latest advancements in material engineering, OrthoFX developed a proprietary multi-copolymer to enhance the predictability of aligner performance and deliver efficient orthodontic movement.
- 50% less wear time*
- 8.4x less loading force
- 88% of cases with one or fewer refinements*
"AirFlex with 50% less wear time is a gamechanger to get the patient compliance and treatment outcomes as planned."
- Dr. Neil Warshawsky, Orthodontist & Professor


50% Less Wear Time
AirFlex is the first and only FDA-cleared aligner system designed explicitly for 12 hours of continuous daily wear time, without extending treatment duration.*
Designed to keep treatment on-track, AirFlex’s proprietary multi-copolymer utilizes sustained ideal force delivery, supporting natural bone tissue remodeling to compensate against day-time relapse.

8.4x Less Loading Force
With industry aligners, very little strain (5%) results in excessive stress that is greater by 20x the optimal force. With AirFlex™ aligners, stress and strain have been decoupled, resulting in strain control within the working range without increasing stress.
During the loading phase, gentle forces are vital and help spare the immediate shock of pain on initial aligner insertion. The OrthoFX AirFlex aligner loading force of 147 g-f is approximately 8.4X less at 5% deflection from the industry standard aligner (1,243 g-f).*

88% Cases with ≤ 1 Refinements
AirFlex's groundbreaking predictability offers a smoother treatment experience for both your practice and your patient.
The multi-copolymer features a highly adaptable inner surface designed to conform precisely to the tooth's outer surface, ensuring an exact fit and preventing the aligner from unseating. HyperElastic technology expands the elastic range, accommodating up to 4 weeks of tooth movement, reducing relapse from non-wear and minimizing refinements.

AirFlex FAQs
What are the patient wear instructions?
12 hours of continuous daily wear. Aligners changed at 7-day intervals or as instructed by a doctor.
Will AirFlex aligners increase treatment duration?
No. AirFlex aligners will not increase treatment duration. For example, if the treatment duration is of 12 months if wearing another aligners brand, AirFlex treatment duration will be of a comparable treatment time. The difference is that patients will only need to wear their aligners continuously for 12 hours a day instead of the 20-22 hours required by other aligner brands.
Do other brands offer shorter wear time?
No, AirFlex aligners are the only patented and FDA-cleared aligner system designed explicitly for shorter wear time. Other aligner brands require 20 to 22 hours of daily wear time versus 12 hours of continuous wear time for AirFlex.
Are there other brands with 12 hour wear aligners?
There are other brands promoting night wear aligners, but AirFlex aligners are the only patented and FDA-cleared aligners for 12 hours of continuous wear time*. Shorter wear time means more time for patients to live life uninterrupted.
Will patients experience more discomfort and a longer treatment experience with AirFlex aligners?
No, AirFlex aligners with patented HyperElastic technology are designed to straighten teeth using gentle, optimal forces. Leading brand aligners exert more force, which may cause discomfort and pain. They also require 20 to 22 hours of wear time per day versus 12 hours of continuous wear time required for AirFlex™ aligners.
AirFlex is designed to deliver the same treatment duration and you may experience fewer unplanned modifications or refinements.
