- Objectives: The objective of this in vitro study was to evaluate the shear bond strength between the ceramic veneer and additively manufactured titanium with different surface treatments, and to compare with milled titanium. Also, to characterize the surface and the presence of an α-case layer of additively manufactured and milled titanium. Material and Methods: Sixty additively manufactured titanium grade 23, and 20 milled titanium grade 4 cylindrical specimens were divided into four groups based on surface treatments, air-particle abrasion and grinding. After ceramic veneering half of each group were thermocycled. The bond strength was analyzed using a shear bond strength test. The surfaces were analyzed using interferometry and scanning electron microscopy. Results: The grinding procedure and air-particle abrading pressure had no significant effect on the shear bond strength (p =.264 and p =.344). Thermocycling showed a tendency towards an effect but not significant (p =.052). The group with the highest air-abrading pressure showed the highest surface roughness. No presence of an α-case layer was detected in any of the groups. Conclusion: Additively manufactured titanium grade 23 may be veneered with ceramics without prior grinding of the surfaces.
