Restorations were crystallized and adhesively luted to resin dies using resin cement. Specimens were then subjected to 400,000 cycles of chewing in a mastication simulator. A universal testing machine was used to apply a compressive load at a crosshead speed of 1\u00a0mm\/min to the long axis of the tooth with a stainless\u2010steel sphere until fracture occurred.
