Purpose: The system of indirect composite resins is an alternative esthetics treatment aiming to solve some of the problems present in the ceramic restorations and conventional resins. The aim of this study was to evaluate and compare the flexural strength in three points, of two indirect restorative materials, Sinfony® (3M-ESPE) and Ceramage® (Shofu). Materials and Methods: Twelve samples were made of each material with 15 mm diameter and 2 mm thick. After 24 hours of preparation, the discs were subjected to flexural strength test at three points in a universal testing machine EMIC, at constant speed of 0.5 mm/min and load cell of 50 Kgf. The data were analyzed by Student T test, the significance level of 5%. Results: The Ceramage had the highest average (98.90 MPa) of resistance to bending by the method biaxial compared to Sinfony (86.90 MPa), the difference had being statistically significant. Conclusion: Within the limitations of this study, we conclude that the Ceramage showed higher values of flexural strength than Sinfony, being an excellent option of indirect restorative material for the clinician.
