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从未在具有潜在牙科应用的复合材料中用作填充剂。因此，研究的目的是以不同的质量比将这种未改性和重氮盐改性形式的二氧化硅作为光固化甲基丙烯酸复合材料的填料。使用拉曼光谱法证实了修饰过程的有效性。制备了具有改性和未改性的244的甲基丙烯酸复合材料，以及未填充树脂作为对照组。检查了它们的基本理化特性，例如固化深度，在盐水中孵育期间的质量稳定性，抗弯强度和抗压强度。还证明了SYLOID®244改性对所检查复合材料性能的积极影响。
