dc.description.abstractPurpose: This study was done to determine the flexural strength of the three different types of In-Ceram materials and In-Ceram spinell mixed with either 35 Wt% In-Ceram alumina or 38 Wt% In-Ceram zirconia. Materials and methods: Ninety seven bars were prepared representing eleven In-Ceram groups including the the three availalble types of In-Ceram (Alumina, Spinell,and Zirconia) and In-Ceram spinell mixed with either 35 Wt% In-Ceram alumina or 38 Wt% In-Ceram zirconia. In-Ceram alumina and zirconia groups were infiltrated with their corresponding glass or with spinell glass, while spinell In-Ceram groups were infiltrated with three available glasses. The two groups of spinell In-Ceram mixed with 35 wt% alumina In-Ceram were infiltrated with either spinell glass or alumina glass. The last two groups of In-Ceram spinell mixed with 38% zirconia In-Ceram were infiltrated with either spinell glass or zirconia glass. The flexural strength was measured using a four-point bend test. Results: Analysis of variance and Tukey’s multiple comparison post hoc tests demonstrated significant differences among the three original types of In-Ceram, with In-Ceram zirconia having the highest strength (p[less than] 0.05). Mixing In-Ceram spinell with In- Ceram alumina or zirconia did not result in a statistically significant improvement in flexural strength of In-Ceram spinell. Conclusion: Adding 35 Wt% alumina or 35 Wt% zirconia In-Ceram to In-Ceram spinell does not result in a significant increase in the strength of the material (p[less than] 0.05).en_US
