SYLOID® 244 has never been applied as a filler in composites with potential dental application. Therefore, the aim of research was to apply this silica in its unmodified and diazonium salt-modified forms in different mass ratios as fillers in light-cured methacrylic composites. The effectiveness of modification process was confirmed with the use of Raman spectroscopy. Methacrylic composites with the modified and unmodified SYLOID® 244, as well as unfilled resin as a control group were prepared. Their basic physicochemical properties, such as depth of cure, mass stability during incubation in saline, flexural and compressive strengths were examined. A positive effect of SYLOID® 244 modification on the properties of the examined composites was also demonstrated. The obtained results proved the high applicability of SYLOID® 244 as a filler in composites with potential dental applications.
SYLOID® 244从未被用作具有潜在牙科应用的复合材料中的填料。因此，本研究的目的是将这种未改性和重氮盐改性形式的二氧化硅以不同质量比用作光固化甲基丙烯酸复合材料中的填料。通过拉曼光谱证实了改性过程的有效性。制备了含有改性和未改性SYLOID® 244的甲基丙烯酸复合材料，以及作为对照组的未填充树脂。检测了它们的基本物理化学性质，如固化深度、在盐水中孵育期间的质量稳定性、弯曲强度和压缩强度。还证明了SYLOID® 244改性对所检测复合材料性能的积极影响。所得结果证明了SYLOID® 244作为具有潜在牙科应用的复合材料中的填料具有很高的适用性。
