This video documents my workflow for scanning in veneers with Primescan.  This technique works well for Omnicam users, however, a light mist of Optispray will be needed to define the interproximal margin zone when using Omnicam.  Primescan has solved so many scanning issues of its predecessors (Omnicam and Bluecam).  Primescan is definitely a dream and captures thin enamel margins and undercuts to provide well-defined images and clean margins.
