Abstract

The purpose of this study was to investigate and analyze fracture toughness (KIc) of yttria stabilized tetragonal zirconia (Y-TZP) dental ceramics by the Vickers indentation fracture test (VIF). In order to determine fracture toughness, the Vickers indenter was used under the load of 294.20 N (HV30). The cracks, which occur from the corners of a Vickers indentation, were measured and used for fracture toughness determination, through the different mathematical models (according to Anstis, Casellas, Palmqvist and Niihara).
