I had a chat with Dr. A about retainers as well. He usually puts in a bonded retainer on the lowers and an essix retainer on top because apparently having essix top and bottom takes some getting used t0 (too bulky?). Given that my regular dentist is strongly recommending removable retainers. I'm going to look into my insurance coverage to see if it will cover Vivera for the first year and then maybe I can just get the essix retainers once I'm into night time wear only. Anyhow, I think he's going to take a close look and determine if I need to go for another round of refinements after tray 20.
