TLZ compared to pfm

This is a demonstration that was conducted at our laboratory comparing the fracture toughness of conventional porcelain fused to metal crowns and bridges to the TLZ crown. Below is the result of driving crowns into a wood plank with a hammer. The TLZ crown exhibited no change while the pfm restorations were destroyed.
