For the present case, the quality in the fabrication of the individual hybrid abutment was good, with a mean deviation of 42 μm (±43) between the original CAD design and the mesh of the zirconia abutment captured intraorally. It must be noted that the presence of a little hole on the top of the actual abutment (very useful to facilitate the outflow of the cement in excess, during the extraoral cementation in the laboratory of the upper zirconia portion on the titanium base), depicted here in dark blue, may increase the mathematical error; however, this is clinically not relevant. The software used for this calculations was a powerful reverse engineering (Studio 2012, Geomagics, Morrisville, NC, USA) able to detect deviations up to 1 μm
