摘要： Silica gels of a mean grain size of about 0.5 to 50 .mu.m are subjected to a heat or acid treatment that considerably reduces their surface area and the volume of pores smaller than 50 nm, while maintaining approximately the same grain size distribution and amorphous structure. These products are colorless and can be worked into a resinous molding material in relatively large quantities, especially as a filler for dental materials based on polymerizable monomers, in particular mono-, di- or polyfunctional esters of acrylic or methacrylic acid. In the completely hardened condition, these materials have good mechanical characteristics, less polymerization shrinkage, very low thermal expansion coefficients, excellent transparency and tooth similarity resulting from the favorable refractive index of the filler, as well as very good ability to be polished and abrasion resistance.
摘要翻译： 对平均粒度约0.5-50μm的硅胶进行热处理或酸处理，可大大降低其表面积和小于50nm的孔的体积，同时保持大致相同的晶粒尺寸分布和无定形结构。 这些产品是无色的并且可以相对大量地加工成树脂成型材料，特别是作为基于可聚合单体的牙科材料的填料，特别是丙烯酸或甲基丙烯酸的单，二或多官能酯。 在完全硬化的条件下，这些材料具有良好的机械特性，较少的聚合收缩率，非常低的热膨胀系数，优异的透明性和由于填料的有利折射率导致的齿相似性以及极好的抛光和耐磨性能 。

摘要： The invention relates to light-activated teeth whitening compositions, and to the use thereof for lightening teeth. The inventive whitening agent contains riboflavin and or the derivatives thereof, which enable the oxidant in the whitening agent to decompose more rapidly, by means of radiation energy, thus effectively accelerating the whitening action. The invention especially relates to single-constituent or dual-constituent materials that have a stable pasty form and can be optionally additionally chemically activated.
