This data set contains a spreadsheet regarding data from the segmentation and evaluation of zirconia, polymethylmethacrylate (PMMA), graphene, and polyetheretherketone (PEEK) crowns in different CT system and acquisiton protocols combinations. CT systems included: 3D Accuitomo 170, Newtom VGi evo, Veraview X800, SOMATOM Force, and NAEOTOM Alpha CT systems. The data includes the difference between the reference crown and evaluated crowns' volume, as well as root mean square error value obtained through the Part Comparison analysis. For some combinations of crown material and CT systems, the surface area was algo obtained.
