  1. Different superscript letters within the α and P10 columns are statistically significant differences based on a 95% confidence interval (CI). α: characteristic strength or scale of a Weibull parameter. β: the shape, slope, modulus of a Weibull parameter. P10: estimation at 10% probability of failure. FM: failure modes percentage; (A) adhesive failure at ceramic-resin interface, (C) cohesive failure at the resin cement, and (M) mixed failure.
