They were divided into two primary groups (n=38) based on two brands: IPS Emax CAD LT (Ivoclar Vivadent) designated as (E), and Initial Lisi LT/B1 (GC America) designated as (L). Each primary group was further split into two subgroups (n=19) based on surface treatment: group E into (E0 & E1) and group L into (L0 & L1). Half of the specimens were subjected to flexural testing without chewing simulation cycles and designated as (E0 and L0), while the remainder were tested after 24× 104 cycles of chewing simulation and designated as (E1 and L1). The ceramic surfaces were examined using SEM before and after loading.Statistical Analysis: Data were gathered, organized, and subjected to Shapiro–Wilk’s and Levene’s tests (p-value < 0.05), followed by analysis with Brown-Forsythe two-way ANOVA and Tamhane’s post hoc tests to assess group differences (p-value < 0.05).Results: There were significant statistical differences in the flexural strength values between the different brand groups before and after chewing simulation (p-value < 0.05). The IPS Emax CAD group showed values approximately twice that of the Initial Lisi group (307.2– 310.5 MPa ± 48.5– 67 vs 148.1– 158.5 MPa ± 24.6– 25.6).Conclusion: Within the limitation of the current study, the following may be concluded: 1. The study’s findings suggest that Initial Lisi blocks should not be used for posterior teeth restorations. 2. This study can provide valuable insights for dental professionals to make informed decisions about which material is most appropriate for various clinical situations.Keywords: lithium disilicate, flexural strength, ceramics, mastication |
