Yeah, if it's in "patent hell and FDA hell" there should be applications and evidence of that online, right?

  Patent hell should be over if this was invented in 1985.

    who knows. maybe invented as a concept and then developed as a concrete dentistry protocol, which then got parented recently?

      Good point. But that would be odd then to present it as solved in 1985 if only recently was figured out how to put it into a protocol. That would be a new innovation rather than “been around forever but never used.”
