Just browsing around for scanners and I am trying to figure out what exactly the differences are between the Zirkonzahn Arti series of scanners. The catalogue points out almost the same information for each scanner while I am trying to figure out which one would be best suited for the lab. It is regarding a crown and bridge lab. For all I know the S300 suffices but would hate the 'if I had only known before' moment! Any Arti experience out there?
