Three Great Choices for Aligners

GT FLEX Clear Aligner Materials - Original, PRO, and MAX

All three GT FLEX ® materials are excellent options for clear aligners. They each offer greater flexibility and strength than most comparable materials available today – usually at a better price!

Two, Extra-Strength Options for Retainers

GT FLEX Clear Retainer Materials - PRO and MAX

We engineered GT FLEX PRO and GT FLEX MAX to be *10-50x stronger* than GT FLEX ORIGINAL, making them the go-to options for clear retainers. But we didn’t forget about flexibility. In fact, both PRO and MAX are more flexible than ORIGINAL, despite their added strength, which lends an extra element of comfort to PRO and MAX retainers.

BPA-Free, Latex-Free, Phthalate-Free, and Gluten-Free

The GT FLEX materials are engineered with patient health and safety in mind. The materials are 100% free of BPA, latex, phthalate, and gluten.

Proven Success

GT FLEX ® aligner & retainer materials are helping dentists around the world achieve great outcomes for their patients.

In the example below, the treatment plan addressed crowding issues, midline adjustments, general alignment of teeth, and bite correction. It also included IPR and attachments.

In total, 8 upper and 16 lower GT FLEX aligners were used in the initial treatment phase, followed by a series of 6 upper GT FLEX aligners for refinement.

Read on… We have a lot more to share about GT FLEX!

High Strength and High Flexibility

The ability to provide both high strength (for fracture resistance) and high flexibility (for comfortable tooth movement) is one of the key advantages of the GT FLEX clear aligner & retainer materials. In many materials, if you increase flexibility you risk losing strength. But GT FLEX delivers both strength and flexibility at the same time.

More Continuous Force

All clear aligners lose strength over the time that they are worn in the mouth. If the strength at which they push against the teeth starts too low or changes too rapidly, it makes it very difficult to get effective, predictable tooth movement.

But GT FLEX applies a more continuous, effective force over time, helping you achieve more predictable tooth movement:

GT FLEX Clear Aligner Material - Continuous Force
Stress Relaxation tests measure the ability of a material (e.g. a clear aligner) to continue to apply force to other objects (e.g. to move teeth) before relaxing into a new shape that no longer applies the same force.

GT FLEX excels at maintaining a more continuous force.

Ultra-Low Water Absorption

The GT FLEX clear aligner & retainer materials have ultra-low water absorption – measured at just 0.14% in 24 hours – which helps them stay clear and odor free in the mouth. It also helps make GT FLEX…

Easy to Use

Some aligner and retainer materials need to be processed within 15 minutes of removing them from their protective pouches. This is typically due to excess water absorption. If the material absorbs too much water prior to processing, the heat from the thermoforming machine will turn that water into steam. And that steam will create bubbles, which reduce both the clarity and the strength of the final aligner.

With its ultra-low water absorption, GT FLEX has no 15-minute processing restriction. You can effectively process it at your leisure, and it’s unlikely to form bubbles during processing.

Dual, Protective Lamination

The GT FLEX clear aligner & retainer materials come with a super-thin, protective lamination on both sides. These protective layers are designed to stay in place throughout the thermoforming process. They help protect the aligner or retainer from absorbing potentially nasty chemicals from the printed models and from dust or other debris that could reduce the clarity of the finished aligner or retainer.

They also provide a generally higher level of sanitation to the finished aligner or retainer – some dentists even deliver the aligners or retainers to patients with these protective layers still in place.

Durable and Comfortable

With their unique combination of high strength and high flexibility, clear aligners and retainers made with the GT FLEX materials are both durable (fracture-resistant) and comfortable.

Unique & Patent-Pending

The GT FLEX materials incorporate a variety of proprietary innovations, all designed to help make them perform better as aligner materials. And the GT FLEX PRO and GT FLEX MAX materials are patent-pending worldwide.

What People Are Saying

GT FLEX is incredible. Dentists love it because it’s really comfortable for their patients and works well. I love how easy it is to use in our lab. We’ll be making a lot of aligners this year and we’ll be making them with GT FLEX. Vinh Lam, Director of Business Development, Oral Image

I’m very impressed with GT FLEX. I’ll be ordering more. Dr. Matt Walton, Owner, Walton Orthodontics

Patients are saying GT FLEX gives a ‘snugglier’, more comfortable fit. Dr. Marco Navarro, Owner, Advanced Orthodontics Studio

Our first impressions of the GT FLEX materials are amazing. The clarity of GT FLEX Original is incredible. It’s like nothing we’ve seen so far. It’s impossible to see the aligners on our patients when they’re wearing them. Bian Paul, Owner, Corona Dentis
