Table 1.

Mechanical properties of the studied materials. Mean flexural strength (σ_F), Vickers hardness (HV), fracture toughness (K_Ic) and respective standard deviation values (SD).

Material	σ_F ± SD (MPa)^*	HV ± SD (GPa)	K_Ic (MPa.m^1/2)^**
3Y-PSZ	878 ± 97^a	13.6 ± 0.8	5.0
5Y-PSZ	641 ± 132^b	13.8 ± 0.1	2.4

Mean values followed by different letters in the same column are statistically different (p<0.05).
