Hi, I'm due to have my braces removed and I'm due to have 2 implants in the top lateral incisor positions. My implantologist suggested that he will place temporary crowns immediately after the implants are inserted. However, I need to wear retainers due to the recent orthodontic treatment. Can I use Essix retainers over the temporary implant crowns? Would it not be better to have an Essix retainer with composite material to mask the gaps instead?
