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.
