An analysis of the flexural strength of two groups of bisacrylic resins and one group of acrylic resins was carried out to achieve this objective. The methodology used was based on a mixed quasi-experimental approach. A total of 90 samples were worked with, distributed respectively in three groups: one of acrylic resin and two of acrylic resin; each group included 30 samples of the following materials: Structur 2 from VOCO, Protemp 4 from 3M, and Alike from GC. These samples were transferred to the stress and vibration analysis laboratory of the National Polytechnic School, where they were subjected to a three-point flexural strength test using a Shimadzu universal testing machine. This made it possible to determine the total fracture point of the material and calculate its resistance in megapascals; the results achieved were as follows: Structur 2 (88.4 MPa), Alike (79.2 MPa), and Protemp 4 (75.73 MPa). Consequently, it was concluded that bisacrylic resins, due to the amount and type of filler present in their composition, exhibit higher flexural strength than acrylic resins; in this study, Structure 2, belonging to the group of bisacrylic resins, showed the highest strength. As a recommendation for future research, another group of acrylic resins should be included to obtain a complete comparison between acrylic and bisacrylic resins in terms of flexural strength. |
