The flexural strength and resilience of the new resin nanoceramic material LVU are greater than those of MZ, EMP, VM2, and TEC.  The flexural modulus of LVU is statistically lower than EMP and VM2, and statistically not different from MZ and TEC.  The combination of high strength and low modulus give LVU a high resilience, as shown by its modulus of resilience, which is statistically significantly higher than other materials tested in this study.  LVU can absorb significantly more stress than other materials without suffering permanent deformation or failure.   The high strength of LVU helps support its use in demanding single-unit restorations, including posterior crowns and implant crowns.
