Copings were made in the DMLS machine [EOSINT M270, EOS GmbH, Germany, Figure 7]. The ten working models were read by the scanner, using Cambridge software, by an experienced dental technician. Cobalt-chromium copings of 0.5 mm thickness, with a 50 μm of cement film thickness and short of their cervical margin by 0.5 mm, were designed.

DMLS technology fuses metal powder into a solid part by melting it locally using the focused laser beam and was builtup additively layer by layer, using layers of 20 μm thickness. A total of 10 DMLS copings were fabricated [Figure 8].
