What is the best type of retainer to use after Invisalign?

Hi, thanks for sending your question. The best retainers system in my opinion is the Vivera system with Invisalign. Since you have 4 retainers, you have excellent reassurance. You may choose to alternate by wearing one retainer at night and another during the day time. Also the flexibility to have multiple retainers in case something happens to another one is great.

Hello
The choice of one type of retainer or another will depend on what the dentist considers to be best for the specific case of that patient. However, the patient must receive the information in a clear and understandable language and agree
Regards.

Each set of Vivera should last up to a year. No need to get a new one every couple of months. Find an Invisalign provider near you to get your Vivera by just going to Invisalign.com. I highly recommend Vivera for post Invisalign treatment. Hawley is old school and uncomfortable to wear. 

I highly rec o mend the Vivera retainers. Although your dentist is no longer practicing, you should find another dentist that does Invisalign. They can even transfer your case to the new provider. A new scan or impressions can be sent, if you feel that your current retainer doesn’t fit properly, otherwise new ones can be ordered right from you old account.
