Patients can maintain their beautiful new smile with our Retainer Subscription Program. Vivera_® retainers are clear retainers used to protect the results of Invisalign_® treatment. They look like Invisalign aligners and are made of the same premium-grade SmartTrack material, but they are designed to keep teeth in place, not move them. Vivera_® retainers provide patients the durability, comfort, strength, and effectiveness that they were provided with Invisalign_®.
