Pressed lithium disilicate glass ceramics: Microstructural characterization, in vitro and in silico nonlinear dynamic analysis for biaxial flexural strength

PURPOSE: To evaluate the mechanical properties of lithium disilicates, and to assess the predictive capability of in silico models for biaxial flexural strength (BFS). MATERIALS AND METHODS: ] and Weibull modulus [m]. RESULTS: than Vintage Prime and LiSi Press, whereas e.max Press demonstrated similar values to all materials. Vintage Prime demonstrated the highest m among the materials. Similar load-displacement curves from in vitro and in silico BFS were obtained for all materials. CONCLUSIONS: Vintage Prime exhibited higher fracture toughness and m compared to the other materials. The BFS and FEA results were consistent, reinforcing the FEA value as a complementary analytical tool for interpreting material behavior under controlled conditions.
