Invisalign: Q&A
Ask a QuestionHow 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
There is an U for the upper and an L for the lower and there is a number next to that which signifies the aligner. Use number 4. If you only had 4 aligners then thats your last one and its safe to wear. If you had 10 or 20 then number 4 is not recommended to wear.

Normally invisalign is numbered low to high
The first aligner is #1 and the last one is #20 (if there were 20). It sounds like you were an Express case? only 4 total?
In a pinch, the dental office can take impressions and send to a local lab. Normal turnaround time for this is only 2-3 days.
