Abstract Objective Resin-based luting agents (RBLAs) with tuned elastic moduli ( E ) were prepared and their influence on the strengthening, reliability, and mode of failure of luted feldspar ceramic was investigated. Methods RBLAs with low E (2.6 GPa), intermediate E (6.6 GPa), and high E (13.3 GPa...
