Second video in the dual-arch series. This dual-arch CEREC 4.0 case series (01, 02, & 03) will demonstrate the screen workflow steps for the CEREC 4.0 software. There are a few icon changes in the side panel and the updated Shape (Anatomical and Circular) names that will be updated in the 4.0 final build. The principles of design remain the same. This video made in the 4.0 245 beta version.
