OBJECTIVE: The objective of this study was to evaluate the resin-composite micro-shear bond strength to zirconia using different techniques of surface treatment.
MATERIALS AND METHODS: Fully sintered zirconia (LAVA, 3M-ESPE, Seefeld, Germany) discs were used in combination with resin-composite (Filtek Supreme, 3M-ESPE, Seefeld, Germany) discs and divided into four groups of surface treatments. The micro-shear bond strength was measured by applying an axial load on the bonded interface until failure occurred. Failure load (N) was determined and the samples were examined under a SEM and the failure type was identified. One-way analysis of variance (ANOVA) was used to analyze the data with the level of significance α = 0.05.
RESULTS: Data analysis revealed significant difference between the different tested surface treatments with the group using sandblasting and coated with an experimental primer showing the highest failure load and a cohesive fracture pattern.
CONCLUSION: Within the limitations of this in vitro study the use of an experimental primer achieved a better bond strength in combination with air-abrasion particles.
