How Are Invisalign Trays Numbered?
I am finished with my treatment & have saved my last 2 sets of aligners incase my retainers broke. Well, my retainer broke and I'd like to use my last set again until my new retainer comes in. I have one set that's labeled 03 and one that is 04. I can not remember which was the last set in my case.
Numbers are laser inscribed on each aligner
Normally invisalign is numbered low to high
