Practitioners speak out
For over 3 years, we have received very positive feedback.
Dr. Nicolas Philippides
Orthodontist in Lausanne

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.
Dr. David Couchat
Orthodontist in Marseille

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.

I am deeply impressed by the quality and innovation of eZtain. These custom fixed retainers fit perfectly and offer great comfort, which makes all the difference for my patients.
Dr. Gauthier Bodart
Orthodontist in Annecy

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.
Dr. Aurore Delavierre
Orthodontist in Orléans

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.
