Fracture Load of Monolithic Zirconia Crowns with Varying Occlusal Thicknesses

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 STML/UTML Kuraray)and lithium disilicate (IPS e.max CAD LT, Ivoclar Vivadent) (control). Teeth were prepared with 0.5 or 1.0mm occlusal reduction and scanned (Omnicam, Dentsply/Sirona).
