The effects of viscoelastic parameters on residual stress development in a zirconia/glass bilayer dental ceramic Taskonak B et al. - Heat treatments produced significant differences between the mean flexural strengths of the heat treatment groups when the specimens were cooled using a fast cooling rate. However, there was not a significant difference between the mean flexural strengths of the heat treatment groups when a slow cooling rate was used. Fractures initiated from the veneer surfaces of the specimens [more...]
