Sadly, as much as I would like the content all to be true, 'Quack' is my assessment too. They say they have been selling this in Austria for 11 years but want crowdfunding to take it abroad. Somehow that does not add up.
And in my experience dentists are really pretty open to innovation, especially 3d scanning and machining. Most recently I got a grinding guard and instead of taking an impression my dentist actually used a Danish scanner that pieced together a couple of hundred individual photos.
