Abstract :

: In this project, a dental composite has been prepared using Bis-GMA, UDMA, and TEGDMA resins along with quartz and barium aluminosilicate fillers containing fluoride. After the fabrication stage, FTIR tests were performed to study the surface modification of fillers, UTM to determine the flexural strength and stiffness test. Then, SEM images were obtained from the fracture surfaces of the bending test. The results of the UTM test were about 23% higher than the standard level of ISO4049 (93MPa) and the hardness test result was 84.4 HV, which is in the acceptable range for dental composites. FTIR peaks related to quartz and barium silicate glass systems showed the success of the silanization process in these two systems. In general, it seems that the composition prepared in this study can meet the requirements of a dental composite. However, further studies need to be carried out.
