Abstract
To determine the influence of the fracture toughness (K${IC}$) methods [single-edge-V-notch-beam (SEVNB) and chevron-notch-beam (CNB)] as well as an optional heat treatment on the K${IC}$ of three different zirconia generations (1st: ZI, 3rd: FX, 4th: HT). One hundred and twenty specimens each (3×4×45 mm) were fabricated, sintered, notched (n=360) and half of them heat treated before K${IC}$ measurements with 4-point-flexural-strength test. SEM images of the notches were recorded. Highest K${IC}$
