Abstract Calcium montmorillonite and montmorillonite with hydroxyapatite layer were used as fillers with remineralizing potential in composites for dental applications. These fillers were also modified using silane to improve their adhesion to the methacrylic resin. The effectiveness of fillers preparation has been confirmed by techniques such as X-ray Diffractometry, Scanning Electron Microscopy, Energy Dispersive Spectroscopy, Transmission Electron Microscopy, Nitrogen adsorption/desorption measurements, and Fourier-Transform Infrared Spectroscopy. Calcium incorporation, mineralization of hydroxyapatite on the surface of montmorillonite, and particles silanization were conducted successfully. The usefulness of these composites as dental fillings was determined by examining the following properties: degree of conversion, depth of cure, flexural and compressive strength, mass stability, and remineralizing potential, understood as the ability to release calcium ions in the conditions simulating natural oral environment. All composites with calcium and hydroxyapatite forms of montmorillonite show the ability to release Ca2+; however, the remineralizing potential of calcium form of this mineral is significantly higher. Due to the ability to incorporate and release calcium ions, it is worth conducting further research on the application of this calcium-rich form of montmorillonite as an active filler in composites with potential dental applications.

钙蒙脱石和具有羟基磷灰石层的蒙脱石作为具有再矿化潜力的牙科复合材料中的填料

摘要 钙蒙脱石和具有羟基磷灰石层的蒙脱石被用作牙科复合材料中具有再矿化潜力的填料。这些填料还使用硅烷进行改性，以提高它们对甲基丙烯酸树脂的粘附力。填料制备的有效性已通过 X 射线衍射、扫描电子显微镜、能量色散光谱、透射电子显微镜、氮吸附/解吸测量和傅里叶变换红外光谱等技术得到证实。钙的掺入、羟基磷灰石在蒙脱石表面的矿化和颗粒硅烷化均成功进行。这些复合材料作为牙科填充物的有用性是通过检查以下特性来确定的：转化程度、固化深度、弯曲和压缩强度、质量稳定性和再矿化潜力，理解为在模拟自然口腔环境的条件下释放钙离子的能力。所有含有钙和羟基磷灰石形式的蒙脱石的复合材料都显示出释放 Ca2+ 的能力；然而，这种矿物质的钙形式的再矿化潜力要高得多。由于具有结合和释放钙离子的能力，值得进一步研究这种富含钙的蒙脱石作为活性填料在具有潜在牙科应用的复合材料中的应用。所有含有钙和羟基磷灰石形式的蒙脱石的复合材料都显示出释放 Ca2+ 的能力；然而，这种矿物质的钙形式的再矿化潜力要高得多。由于具有结合和释放钙离子的能力，值得进一步研究这种富含钙的蒙脱石作为活性填料在具有潜在牙科应用的复合材料中的应用。所有含有钙和羟基磷灰石形式的蒙脱石的复合材料都显示出释放 Ca2+ 的能力；然而，这种矿物质的钙形式的再矿化潜力要高得多。由于具有结合和释放钙离子的能力，值得进一步研究这种富含钙的蒙脱石作为活性填料在具有潜在牙科应用的复合材料中的应用。
