Not everything can be done in the scanning software parameters settings , some depends how software will aligned upper/lower ( sometimes it can be off a little) some depends on the mill calibration .
Most of the doctors going to restorative part without making temps and custom impression copings to manage tissue . It is why we end up with the tissue overlap .

I did see scanner at the Grater New York dental show . Scanner with the software around $20k .
John , I agree with you ; primopattern will not work in the mouth , but work fine for me at the bench . Primotec have more stuff that you can use for jig and like you said - what work for one, may not work for other .
I can't see yours video , but I think if you work in dental office , this is the way to go .
