Background: This study aimed to evaluate the shear bond strength (SBS) of ceramic and titanium substructures produced by different methods. Methods: After designing 51 disc-shaped samples, three groups were created according to material type and manufacturing method Cobalt-chromium (Co-Cr) group prepared by selective laser melting (GC), titanium group prepared by milling (GTi1) and titanium group prepared by selective laser melting (GTi2). Surface roughness values (Ra, Rz) of six samples from each group were examined and scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDX) analyses were applied to one specimen from each group, and failures were examined using a stereomicroscope. Results: The mean SBS, Ra and Rz values for GC were 21.21 ± 6.15 MPa, 5.79 ± 0.58 µm and 37.54 ± 6.87 µm; GTi1 were 25.80 ± 7.79 MPa, 2.69 ± 0.41 µm and 26.05 ± 7.60 µm; GTi2 were 24.32 ± 7.07 MPa, 5.91 ± 0.51 µm and 44.46 ± 7.78 µm respectively. Although the shear bond strength did not show a significant difference between the groups, the roughness values of the GTi1 group were statistically significantly lower than those of the other groups (p < 0.05). The roughness values of the GTi2 and GC groups did not show a statistically significant difference (p > 0.05). Conclusions: The ceramic bonding of titanium specimens produced by both methods showed values similar to those of Co-Cr and ceramic bonding used in routine treatments.
