I'm getting my wisdom teeth out (just the right side, I had the left side out 5 years ago; they are erupted and not terrible, but they are hard to clean and would be better if gone) in a few days, and Boing Boing had a piece about the panoramic X-rays for facial maxilo images. You stand with your chin in a brace and the machine rotates around you. Pretty exciting. I got one done, so I'll try to get it and post it.
In the mean time, learn more about Scanora, the "top quality imaging system for the difficult dento-maxillo-facial area " It's an exciting time in dental X-rays, friends.
