The ordering process, step by step
- Look for eZtain Lab among your intraoral scanner’s partners.
- If you can’t find us, or if you use an iTero scanner, please contact us.
- Check-up appointment before debonding: an intraoral scan is taken.
- The STL file is automatically uploaded from the scanner to our laboratory.
- To confirm your order, send the prescription from your eZtain practitioner portal.
- Order in three clicks, with delivery within one week at most.
- Our teams of dental technicians design your orthodontic retainers using our proprietary software.
- Modeling is done in all three spatial dimensions to produce a retainer perfectly fitted to your patients’ dental morphology, taking the occlusion into account for the upper arch.
- Our teams mill your PEEK retainer wires.
- Thanks to high-performance 5-axis dental milling machines, we can guarantee precision of around 3 µm.
- The fit of each retainer is checked on the models you provided.
- The retainers are then cleaned and decontaminated.
- Your retainers are shipped by tracked mail.
- We strive to ensure you receive your retainers at your practice within 7 days of the prescription date.
- At the next appointment, you can proceed with bonding the retainers.
- You can keep all your usual protocols and adhesives.
- No adjustment needed: the wire is perfectly fitted to your patient’s morphology.
