I help doctors submit for refinements/ additional aligners every day. Here’s what I need to know first:
1. What aligner is the patient currently holding on?
2. Did you take new scan/impression?
3. Did you remove the old attachments before the impression?
Here’s a guide to doing it yourself: https://www.youtube.com/watch?v=WeZxTnM81AU&t=1506s
