eZtain Lab

designs and manufactures custom orthodontic retainers made of PEEK, a biocompatible, durable, and aesthetic material.


Thanks to a 100% digital approach (intra-oral impressions, CAD/CAM modeling, 5-axis CNC machining), eZtain retainers offer a perfect fit and superior resistance compared to traditional metal wires.


Developed in collaboration with orthodontists and INSA engineers, they ensure optimal post-treatment stability.

eZtain Lab is aimed at modern orthodontists who want to offer their patients a discreet, reliable, and innovative solution.
