Ivan worked at Align and was CTO of European DTC competitor. I agree with Ivan that both technologies have their sweet spot. I disagree with the scale piece and the frequency of visits as there are practices doing both those things differently using the placement and remote monitoring technology.

For younger patients that haven’t had braces before which is the majority of historical patient populations and future ones, 3D printed personalized braces systems are better as the tooth movement needed is more clinically substantial at tougher angles. Many younger patients forget and lose their plastic aligners.

That said: what is chosen should be what for the whole person at multiple levels.

This sounds like AI-written comment, at least in the first part. What I do not get is why are you dismissing the argument about number of visits. 3D printed braces are still braces. They require manual adjustment for each treatment stage. Aligners do not need that - they may need a check-up in the middle of the treatment, maybe one or two mid-course corrections, maybe an appointment for installation of attachments, but that's it. You change aligners at home without visiting doctor.

They can get a new one easily by post.
