Abstract:

Newer translucent zirconia materials may have different minimum occlusal thickness requirements based on type of cement. Objective The purpose of this study was to evaluate the effect of occlusal thickness and cement type on the fracture load of crowns made with three all-ceramic materials. Methods One-hundred twenty extracted maxillary human third molar teeth were divided into three groups and restored with crowns using cubic-containing 4Y- PSZ and 5Y- PSZ zirconia Katana STMLUTML Kurarayand lithium disilicate IPS e.max CAD LT, Ivoclar Vivadent control. Teeth were prepared with 0.5 or 1.0mm occlusal reduction and scanned Omnicam, DentsplySirona.
