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.
The Higher the Number the Closer to Finishing
When it comes to Invisalign trays, typically the higher number would be the last set. So if you have a higher number than odds are that is where you left off.
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.
