Titanium requires special ceramic systems for veneering. This study compared the three‐point bending strength of three commercially available titanium ceramic systems with a NiCr‐alloy with conventional ceramics. Three‐point bend specimens 25 × 5 × 0.5 mm were cast from polyethylene patterns. After α‐case removal, they were veneered with 8 × 5 × 1 mm of ceramics at the center of the bar. Specimens were tested in a universal testing machine without ageing, after thermocycling, and after 90 d storage in an electrolyte solution. Titanium‐ceramic systems were found to have a significantly lower bond strength in comparison to the NiCr‐ceramic system. One of the titanium ceramic systems had a significantly lower bond strength in comparison to the other systems investigated. It could be concluded that bonding between titanium and ceramics is obtainable; however, the achievable bond strengths did not match the NiCr‐ceramic control.
