Effect of sandblasting with different size of aluminum oxide particles on tensile bond strength of resilient liner to denture base

Abstract

Objectives: The purpose of this study was to investigate the bonding properties of sandblasted with different size of aluminum oxide particles denture base to silicone based soft denture liner.

Methods: Polymethyl methacrylate (PMMA) test specimens were fabricated and then randomly assigned to 5 groups (n=15), according to the treatments applied, untreated (control, group 1), sandblasted with 50 µm Al₂O₃ (group 2), 60 µm Al₂O₃ (group 3), 120 µm Al₂O₃ (group 4), and 250 µm Al₂O₃ (group 5). The resilient liner specimens were processed between 2 PMMA blocks. Bonding strength of the liners to PMMA was compared by tensile test with the use of universal testing machine at a crosshead speed of 5 mm/min. The mean value and standard deviation of the specimens were statistically evaluated by 1-way ANOVA and post hoc Tukey-Kramer multiple comparisons tests (α=0.05).

Results: The highest mean force value was observed in group 4 specimens, and the lowest mean force value was observed in group 2 specimens. The differences between groups 1 and 4 was found to be statistically significant (p=0.001). Nevertheless, there was no statistical difference in tensile bond strength between groups 1 (control) and groups 2, 3, and 5 specimens.

Conclusion: Different particle sizes of aluminum oxide particles affect the bond strength of PMMA/resilient liner. Furthermore, 120 µm Al₂O₃ particles are the best particle size to improve strength of the bond.

Keywords: Sandblasting, tensile bond strength, soft liner, aluminum oxide.
