Conclusions :�

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.�
