The first 100% digital fixed retainer made of PEEK that protects your results and saves chair time.
Metal orthodontic retainers are no longer up to the task.
Over one million orthodontic retainers are placed each year in patients across France. These fixed retainers are designed to remain in the mouth for life, maintaining the dental alignment achieved through treatment. However, up to 50% of these orthodontic retainers experience issues over their lifetime.
Currently, the situation can be summarized as follows :
12-50*%
Failure
- Wire breakage
- Debonding
- Adverse effect
≈100%
Hand-bent
- Inaccuracy
- Poor fit
- Discomfort
≈ 1
Support visits per patient over 24 months
- Unbilled chair time
- Disruption of your schedules
- Negative word of mouth

In the Clinic: 3 Steps, Zero Surprises
Step 1 – Digital Impression
- A check-up session is performed before debonding, during which an intraoral scan is taken.
- The STL file is automatically uploaded to our lab directly from the scanner.
Step 2 – Validate Your Prescription
- To confirm your order, simply send the prescription from your eZtain practitioner account.
- Place your order in just three clicks and receive it within a week at most.
Step 3 – Guided Chairside Placement
- At the next appointment, you can proceed with retainer placement.
- You may keep your usual protocols and adhesives—no changes needed.
- No adjustments are required: the wire is perfectly adapted to your patient’s anatomy.

For over 3 years, we’ve received excellent feedback.

eZtain retainers offer exceptional durability and a perfect fit in the mouth. My patients are very enthusiastic about benefiting from a more aesthetic, metal-free retention solution. Moreover, over the past two years, I have observed a reduction in emergency visits related to broken retainers in the clinic, which frees up time for our teams and reduces costs associated with minor relapse treatments.

I frequently use eZtain retainers, which offer the advantage of being very easy to bond and perfectly fitted.
Additionally, because the material is white, patients appreciate the discreet appearance and the absence of metal in their mouths – this is a significant selling point for them.
It also seems logical that this material would help prevent wire-related syndromes caused by metal wires, which is a very promising benefit.

Offering my patients the choice between traditional retainers and eZtain has significantly enhanced their satisfaction. eZtain stands out with its tooth-colored material that blends more naturally, and the absence of metal components is unquestionably a major advantage.

When I present my patients with the choice between a traditional retainer and eZtain, they are immediately drawn to eZtain for its natural shade and metal-free design. I have also been using eZtain for several months now, and I’m impressed by the reliability of these retainers. I recommend it without hesitation.

I can only recommend eZtain retainers. They are extremely precise (I never need to use the positioning key), the delivery is fast, they are aesthetically pleasing, and patients consistently mention how comfortable they are.

In certain clinical situations, I use eZtain retainers as an alternative to traditional metal wires. This solution is especially appreciated by patients looking for a metal-free option. The adaptation and bonding in the mouth are very easy. The eZtain platform simplifies the ordering process, with fast delivery times.

My patients and I are very satisfied with eZtain retainers, which offer a discreet alternative to traditional metal retainers. Bonding is easy even without a repositioning key, and the fit is perfect.
