When you choose between the two aligner systems, here’s what to think about: if you have a lot of tooth movement, spacing, crowding, functional issues, an overbite or underbite, by all means, you have to do Invisalign. You need the attachments and that ability to be able to make room between your teeth, which is the IPR I was referring to.
But for the simple cases like a little crowding or one tooth out of position, by all means, use the less expensive direct-to-consumer aligner system.
