Recently, I have read this scientific article about digital scanning.
More precisely this study compaired Omnicam to Bluecam evaluating the final precision of the prosthetic teeth after their milling. The conclusions fundamental were fundamental two:
1. Crowns fabricated with the Omnicam scanner system had significantly higher vertical discrepancy values than those fabricated with the Bluecam scanner system.
2. A powder application before Omnicam Scanning the vertical fit of the crowns and reduced the volumetric 3D internal fit.
