A zeolite with high ion-exchange potential was used as an active filler with remineralizing potential in composites that can be applied in restorative dentistry. Two calcium-rich forms of the 13X zeolite were obtained by sodium to calcium ion exchange and mineralization of a hydroxyapatite layer. These fillers were also silanized and mixed with methacrylic resins and photoinitiators to obtain composite materials. First, the effectiveness of the filler preparation and silanization was confirmed by X-ray diffractometry, scanning electron microscopy, energy dispersive spectroscopy, transmission electron microscopy, nitrogen adsorption/desorption measurements, thermogravimetric analysis, and Fourier transform infrared spectroscopy. The physicochemical characteristics of composites with silanized and nonsilanized forms of sodium- and calcium-rich 13X zeolite fillers were examined. The 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 a natural oral environment, were determined. The effect of ion exchange, hydroxyapatite mineralization, and silanization of fillers on the final composites’ properties was examined. Composites with calcium-rich fillers proved to show the ability to release Ca2+ during incubation in saline for 14 days at 36.6 °C showing therefore remineralizing potential with good values of other parameters.

富含钙的13X沸石，具有可矿化的牙科复合材料填充剂
具有高离子交换电势的沸石被用作具有可再矿化作用的复合材料的活性填料，该复合材料可用于修复性牙科。通过钠到钙离子交换和羟基磷灰石层的矿化获得了两种富含钙的13X沸石。还对这些填料进行硅烷化处理，并与甲基丙烯酸树脂和光引发剂混合以获得复合材料。首先，通过X射线衍射法，扫描电子显微镜，能量分散光谱，透射电子显微镜，氮吸附/解吸测量，热重分析和傅里叶变换红外光谱确认了填料制备和硅烷化的有效性。研究了具有富钠和富钙的13X沸石填料的硅烷化和非硅烷化形式的复合材料的理化特性。确定了转化度，固化深度，挠曲和抗压强度，质量稳定性和再矿化潜力，这被理解为在模拟天然口腔环境下释放钙离子的能力。研究了离子交换，羟基磷灰石矿化和填料硅烷化对最终复合材料性能的影响。具有高钙填料的复合材料被证明具有释放钙的能力 被理解为在模拟自然口腔环境的条件下释放钙离子的能力。研究了离子交换，羟基磷灰石矿化和填料硅烷化对最终复合材料性能的影响。具有高钙填料的复合材料被证明具有释放钙的能力 被理解为在模拟自然口腔环境的条件下释放钙离子的能力。研究了离子交换，羟基磷灰石矿化和填料硅烷化对最终复合材料性能的影响。具有高钙填料的复合材料被证明具有释放钙的能力在36.6°C的盐水中孵育14天期间，其2+值显示出具有其他参数良好值的再矿化潜力。
