I wonder how this works, they added brackets on my teeth that act as anchors. Definitely worth the try, I believe that I paid 3k for my treatments, this is ~600. Amazing
They do not add brackets / anchors but they do use a straight-across aligned as opposed to a more trimmed "scalloped" aligner. The straight across gets a bit more turning force because it goes higher up and covers a bit of your gums. I'm no expert so I don't know if that's the whole story. They definitely filter out people with more complicated alignment issues so that could play a role as well.
