Abstract

Background: The aim of this study was to evaluate ceramic/titanium shear bond strength and microstructure of two commercially dental ceramics. Materials and Methods: Ceramic/titanium bond strength (6.0 mm × 2.0 mm) was measured using a universal testing machine. The load was applied with a crosshead speed of 0.5 mm/min until fracture. The titanium received different modifications for commercially pure titanium (airborne-particle abrasion and acid and thermic treatment). Results: All specimens showed different features within the interfacial area according to the different kinds of surface treatment. The tensile bond strength showed significant difference among the ceramics and surface treatment where the acid treatment groups had least means bond strength as differences between ceramic groups (P = 0.03). Conclusion: It was concluded that the use of acid solutions did not improve titanium-ceramic bonding strength values and the combination of airborne-particle abrasion and thermic treatment produced the most significant improvement in the titanium-ceramic bonding.
