The work he did with the impressions, to me, suggests he has experience as / knows someone who is a dental technician. If he didn't, wow, he independently figured out some of their key techniques.

My grandfather used to make dentures, and that casting in the 4th photo looks exactly like the impressions my GF would make. They also used these hinges so they could mate the upper to the lower, so they could adjust any collisions that occurred while opening and closing the mouth.

Link?

Nope, no prior experience. It's quite easy, if you have an impression tray (I had to mock it up in 3d and print one). The instructions for alginate are right on the bag.

The rest was just reading freely available docs on how to make castings.
