The effect of nonthermal argon plasma surface treatment on the fracture resistance of monolithic zirconia restorations containing tetragonal and cubic grains
Abstract
Purpose: The aim of this study was to investigate the effect of nonthermal
argon plasma (NP) surface treatment on the fracture resistance of monolithic zirconia restorations with different microstructures.
Methods: Twenty restorations were prepared from each of two tetragonal
and two cubic zirconia materials (80 restorations in total). The restorations were then divided into two subgroups (n = 10) for each material
according to the surface treatment applied: air abrasion or NP. The surface
topography of the treated groups was examined using a scanning electron
microscope. All restorations were fixed to metal dies with resin cement,
subjected to thermal cycling, and then underwent fracture resistance testing with a universal testing device. Two-way ANOVA and Bonferroni tests
were used for statistical analysis of the data (α = 0.05).
Results: The type of surface treatment and the type of zirconia material
were shown to significantly affect the fracture resistance of the restorations.
The air-abraded groups showed significantly higher fracture resistance (N)
than the NP groups (P < 0.001).
Conclusion: The results of this study suggest that air abrasion surface
treatment has a more favorable effect on the fracture resistance of tetragonal and cubic zirconia restorations than NP surface treatment.
