Abstract

Objective

The aim of this in vitro study was to investigate the effect of the titanium dioxide formed by anodization process on the titanium–resin cement microshear bond strength.

Methods

Forty titanium cylinders (9 × 11 mm) were randomly divided into 4 groups according to the surface treatment methods: Control group, no treatment; airborne-particle abrasion group, 120 µm Al2O3; primer group, 120 µm Al2O3 +metal primer; and titanium dioxide group, titanium dioxide nanotube (n-TiO2) formed by anodization process. Scanning electron microscope analysis was performed to determine the surface alterations of the specimens. Then, dual-polymerizing resin cement was applied on the specimens by using Tygon tubes, and microshear bond strength tests were performed by using a universal testing machine. The obtained data were analyzed by using 1-way analysis of variance and the Tukey post hoc test (α=0.05).

Results

Each surface treatment application increased the titanium–resin cement bond strength (P < .05). The highest bond strength value was obtained by titanium dioxide nanotube application, and the difference between groups was statistically significant (control group: 4.91 ± 1.10; airborne-particle abrasion group: 5.66 ± 1.90; primer group: 6.700 ± 2.05; and titanium dioxide group: 9.44 ± 1.20) (P < .05). All groups showed an adhesive failure mode.

Conclusion

The formation of titanium dioxide nanotube on titanium by anodization process increased the microshear bond strength significantly higher than that of the airborne-particle abrasion group or the metal primer group.
