I did okay with a trios when I scanned a model. It was pretty easy. A live patient would have a different set of challenges,controlling the environment for the scanner to be successful. It's funny seeing videos of these Doc's holding a foot long device with one hand trying to maneuver it in a tiny space. I'm sure it's not easy.
Well I'm not complaining, I'm just saying what I have seen on scanned files. I'm reading on here and trying to read articles on how to be successful with an oral scanner.
I do want to get a IO scanner but I'm waiting a bit longer to see what Chicago has to offer. Hopefully something smaller.
