alt Hacker NewsI did Invisalign a few years ago. Manufacturing the retainers is surely only a small part of the puzzle.
They used a specialized sort of 3D camera on a stick to get an incredibly accurate model of my mouth, any open source solution would need an equivalent. And you’d also need open source code from somewhere to work out which teeth need to move where and at what stage in the treatment.

AFAIK Align's 3D scanning system is more or less branched from the same Israeli tech that went into the Xbox 360 kinect camera and the iPhone face-ID.

They also use this camera system when creating implants. After the implant post was installed, they scan your mouth to determine the optimum shape for your crown (that goes on the post).
