摘要: The invention relates to a dental composition comprising polymerizable components, an initiator suitable for curing the polymerizable components, a Ca-ions releasing component having a Ca-ions releasing capability of 400 to 700 mg/l (ppm) if 2.5 g Ca-ions releasing component is steered in 50 ml de-ionized water having a pH of 2 for 24 hours; a F-ions releasing component having a F-ions releasing capability of 1,500 to 3,500 mg/l (ppm) if 2.5 g F-ions releasing component is steered in 50 ml de-ionized water having a pH of 7 for 24 hours. The invention also relates to a kit of parts comprising such a dental composition according and the following items alone or in combination: dental adhesive, dental milling block, prefabricated dental crown. The dental composition is suitable for use in a process of remineralizing a defect tooth in the mouth of a mammal, the process comprising the step of fixing a dental restoration to the surface of the defect tooth with the dental composition.

摘要: 一种基于微环境诱导纳米粒子再沉积的牙本质粘接预处理组合物,包含二元体系或者三元体系,该组合物应用在牙本质酸蚀处理之后、粘接剂使用之前。该粘接预处理剂可以在酸蚀后脱矿牙本质基质所构成的天然矿化环境诱导下,迅速在脱矿牙本质基质的极性位点形成的大量ACP纳米颗粒,这些化学结合的无机纳米粒子掩蔽了脱矿牙本质基质的极性,消除牙本质有机质的水化能力,改善粘接界面的脱矿牙本质基质相和粘接剂相的相容性;提高其机械强度,抵抗水挥发时导致的塌陷,从而摆脱牙本质粘接时对水的依赖性,降低临床粘接操作的敏感性和由水残留导致的混合层的不稳定性,可制备为一种牙科粘接预处理剂,适用于口腔所有粘接剂场合。
