What type of retainers should I use after Invisalign? I fixed crossbite

Hello there,Generally speaking, they all are pretty similar.  Some will tell you that Vivera retainers are best, some will tell you that others are best.  I actually provide about 3-4 different options for my patients and the results are great across the board.  Just make sure that you consider your options and pick one that suits you and has some type of replacement offer (in case you loose one or both). Good luck and follow me on Real Self, if you have additional questions.

I'd go with the Invisalign retainer, most likely, as they are much more comfortable and less noticeable than a Hawley.  Wear the Invis for 3-4 months and then sign on for Vivera, which should get you another year.  Many crossbites become self retentive eventually, so follow your orthodontist's advice.
