Fabrication of a custom cast metallic post and core with direct technique is an established clinical procedure for the treatment of endodontically treated teeth with extensive loss of hard dental tissue. Nowadays computer-assisted digital CAD/CAM technologies can be used in fabrication of post and core. Digital techniques shorten the necessary clinical and laboratory procedures and make fabrication easier, quicker and accurate. For each tooth one metal post was fabricated with digital technique using SLM fabrication technology (group A) or one by casting (group B). All teeth were sliced perpendicular to the axis of the post and the thickness of the cement layer was measured. The average cement thickness for group A was 36.76 ± 17.29 µm in cross-section 1 62.38 ± 15.24 µm in cross section 2 129.42 ± 38.37 µm in cross-section 3 and 142.76 ± 36.35 µm in cross section 4. For group B the average cement thickness was 18,18 ± 4,6 µm in cross-section 1,. 15.36 ± 5.41 µm in cross-section 2 25.41 ± 13.42 µm in cross section 3 and 23.69 ± 13.44 µm in cross section 4.
