The aim was to determine the compressive strength of three nanohybrid composite resins, Bulk Fill, which correspond to Filtek ™ 3M, Tetric EvoCeram-Ivoclar Vivadent and Admira Fusion X-tra-Voco stored in distilled water at 37o for 24 h. Materials and Methods: an in vitro, cross-sectional and comparative study was carried out, for which 60 cylindrical samples of 4x8 mm were divided into 3 groups with 20 samples in each. The data obtained and statistically analyzed showed that the compressive strength of Filtek ™ Bulk Fill resin had an average 51,964MPa, minimum 18.30MPa and maximum 85.15 MPa. On the other hand, Tetric® Evo-Ceram Bulk Fill resin had an average 111,607 MPa, minimum 77, 19 MPa and maximum 185, 42 MPa. Finally, the Admira Fusion X-tra Bulk Fill resin had an average 99.273 MPa, minimum 62.87 MPa and maximum 139.26 MPa. In conclusion, we have that Tetric Evo-Ceram resin has a higher compressive strength compared to the other resins evaluated. Keywords: compressive strength, nanohybrid resins, Bulk Fill. |
