How Mavira custom retainers are made
Mavira has been making retainers for over five years. It uses an at-home impression kit and lab fabrication to create custom clear upper and lower retainers. Your impressions provide the shape used for fabrication. The lab reviews the impressions, makes the selected number of matched sets, checks the finished appliances, and ships them to you.
What “custom†means in this process
A custom retainer is fabricated to the dental anatomy captured by your accepted impressions. It is different from a stock mouthguard that comes in a standard size or a boil-and-bite product shaped by heating. Mavira's process begins with separate upper and lower impressions so the lab can fabricate a matched pair.
One Mavira set contains two appliances: one custom upper clear retainer and one custom lower clear retainer. The available one-, two-, and three-set options determine how many matched pairs the lab makes from the order.
The Mavira lab process, step by step
Your kit is prepared
The order begins with the impression materials and instructions needed for upper and lower impressions. Review every step before starting because impression materials have a working time.
You take impressions at home
Follow the kit directions to capture the teeth and surrounding detail. Taking your time with setup and following the sequence exactly can help create a usable result.
Impressions travel to the lab
Use the included return process to send the completed impressions back. Protect them with the supplied packaging and follow the shipping directions in the kit.
The impressions are reviewed
The lab checks whether the impression captures enough usable detail for fabrication. If the impression cannot support the process, Mavira support can explain the next step.
Your retainers are fabricated
The accepted shapes are used to form and finish the clear appliances. The lab makes the exact number of upper-and-lower sets selected with the order.
The finished order is checked and shipped
The appliances are checked against the order before packaging. Once shipped, delivery depends on the carrier and destination. See shipping and fit-support information.
Why impression quality matters
The lab can only fabricate from the anatomy captured in the impression. Missing tooth detail, movement while the material sets, an incorrectly positioned tray, or removing it too early can affect whether the impression can be used. A lab review is therefore an important checkpoint in a mail-in process.
That review is a fabrication check, not a dental diagnosis or a substitute for an oral examination. An impression may look complete enough to make an appliance while a separate health or bite concern still requires a licensed dentist or orthodontist.
Before taking impressions
Read the full instructions, organize the materials, confirm which tray and material to use, and make sure you can complete the timed steps without interruption.
Before mailing impressions
Follow the supplied review and packing directions. Do not trim, reshape, or alter a finished impression unless the kit instructions specifically tell you to do so.
What to check when your retainers arrive
Confirm that the package contains the quantity selected and identify the upper and lower appliances. Inspect each retainer for shipping damage or an obvious material defect before use. Follow the supplied seating and care instructions rather than biting forcefully to push an appliance into place.
A new retainer can feel close or firm, but it should not be forced. If it does not seat fully, has a sharp or damaged edge, or causes significant or persistent pain, stop and contact Mavira support. Keep the retainers, case, kit records, packaging, and order information because support may need details or photos to review the concern.
What clear retainers are—and are not—designed to do
Clear retainers are designed to help maintain the current position of teeth after orthodontic treatment or as directed by a dental professional. They are not active aligners and are not intended to move teeth into a new position. A mail-in impression and lab fabrication process also does not replace routine dental care.
Contact a dental professional before ordering if:
- Your teeth have visibly shifted or your bite feels different.
- Your previous retainer no longer seats fully or causes significant pain.
- You have swelling, bleeding, sores, loose teeth, suspected decay, or another active dental concern.
- You are unsure whether a replacement retainer is appropriate for your current treatment stage.
Clear information before you order
Mavira publishes the total price for each quantity: one set for $120, two sets for $150, and three sets for $180. The three-set option works out to $60 per matched upper-and-lower set. Review the full pricing explanation, shipping and fit-support overview, checkout terms, and official refund policy before ordering.
Mavira lab process questions
Where are Mavira retainers made?
Mavira states that its custom clear retainers are fabricated through its lab process after the mailed impressions are reviewed.
Does the lab use my old retainer?
The mail-in process uses new upper and lower impressions from the kit. Those accepted impressions provide the shape used for fabrication.
What happens if an impression cannot be used?
Contact Mavira support and follow the instructions provided for your order. The appropriate next step depends on what the lab can see in the returned impression.
Does lab review replace a dental exam?
No. The review checks whether an impression can support fabrication. It does not diagnose dental conditions or determine whether active tooth movement is needed.
