The STL\u2010R files were loaded into a computer\u2010aided manufacturing (CAM) machine and a milling disk made of a modified PEEK\u2010based polymer with 20% ceramic fillers was milled into post and core restorations. Each original post and core resin pattern was sprued, invested and pressed using pellets made of the same PEEK material and a PEEK pressing unit. The resulting post and core restorations from the CAD\u2010CAM and heat\u2010pressed methods were scanned to generate STL\u2010M (milled) and STL\u2010P (heat\u2010pressed) files, respectively. STL\u2010M and STL\u2010P files were digitally aligned and compared to STL\u2010R files using a 3D analysis software. The 3D spatial distribution deviation was exported, and the statistical analysis was performed using the 95% CI deviation distribution from the Gaussian function subtraction. The statistical outcome for each group was merged and a 3D color\u2010coded map was created showing the average deviation (\u03b1 = 0.05).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The heat\u2010pressed post and core restoration showed 79 \u00b16% of the areas within \u00b150 \u00b5m while the CAD\u2010CAM post\u2010and\u2010core restoration showed 66 \u00b19%.
