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).

That’s pretty wild. I got a mould taken with some sort of a putty .

I wear a night guard and have had them made both ways.

The 3D camera was really neat. A little faster, and I didn’t once dry heave.

I could watch the software and a 3D model slowly form of my mouth. Looked surprisingly user friendly. Missed areas were highlighted, for example.

Dry heaving would have been great. I would regularly vomit from impressions. My orthodontist would just prepare two sets if impression trays, cause the first one was going to go in the medical waste bin.

Impressions for invisilign (when I did it, about a million years ago) weren't so bad though. Unfortunately invisilign resulted in an open bite for my molars, which I really should go back to an orthodontist to address, but I'd rather not.

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.

While both were originally companies based in Israel, the technology behind the Kinect is different.

iTero scanners (owned by Align Technology) use parallel confocal imaging via red light lasers. Their newer models also use Multi-Direct Capture techniques.

Kinect used a Light Coding technique, an infrared projector and camera. It was developed by a company called PrimeSense, which was later purchased by Apple.
