Lithium disilicate was the most translucent and yet the weakest material, whereas highstrength zirconia was the most opaque ceramic and the strongest. Katana UTML had the highest translucency but was weakest among translucent and highstrength zirconia materials. Overall, translucency was negatively correlated with biaxial flexural strength.

1. Introduction. At room temperature (RT), zirconia is found in the monoclinic crystal structure (space group P 2 1 / c).Zirconia undergoes a firstorder, displacive martensitic transformation at approximately 1170 °C [1] with a volume change in the unit cell by about 4% [2].After the phase transition, zirconia is stabilized in a tetragonal phase (space group P 4 2 / n m c) at temperatures ...
