Unlike other traditional clear retainers, Vivera retainers are made with the same state-of-the-art technology as Invisalign® aligners, custom made from an impression or scan of your teeth is the only orthodontic retainer on the market that does not require an alginate impression (mouth full of putty). Invisalign sends you 4 sets of clear retainers that are created from your final iTero scan.
Pros: thicker and more durable, It also reduces the risk of the retainer cracking or breaking; precise fit and therefore more comfortable fit.
Cons: Any major dental work (veneers, crowns) can affect the fit of all the retainers and require new impressions, retainers and fees
Failure to wear as instructed may cause sufficient relapse to require new impressions, retainers and fees
