Do crystallization and refiring protocols affect the translucency, flexural strength, and Weibull reliability parameters of nanolithium disilicate glass-ceramic?

Key Points

• Translucency levels depended significantly on the final firing temperature, influencing how light passes through the material.
• Flexural strength (BFS) tests revealed HT, MT, and HT-MT specimens had lower strengths for single-unit restorations, suggesting limits for these materials.
• Weibull reliability indicated that while moduli were similar, LT, MO, HT-LT, and HT-MO had greater characteristic strengths, enhancing treatment options.
• The findings underscore the importance of firing protocols on the performance of dental materials, highlighting the need for tailored approaches.
