The invention relates to a composition which is self-adhesive to the hard tooth tissue, comprising: (A) 5 to 75 percent by weight of one or more mono or higher functional ethylenically unsaturated compounds which additionally have an acid functional group, wherein one of said compounds has a P—OH group, for instance a phosphoric, phosphonic or phosphinic acid group; (B) 2 to 50 percent by weight of one or more mono or higher functional ethylenically unsaturated compounds without any acid functional group; (C) 22.8 to 85 percent by weight of filling material(s), comprising at least one filling material that may react with component (A) in the sense of causing a ion exchange, neutralization, salt formation and/or chelate formation reaction; (D) 0.1 to 8 percent by weight of one or more initiators and optionally activators; (E) 0.1 to 20 percent by weight of further additives, for example, modifiers, wherein the weight ration in % of component (A) relative to component (B) ranges from 21 to 90:10 to 79.
本发明涉及一种可自粘于硬质牙齿组织的组合物,该组合物包括:(A) 5%至 75%(重量百分比)的一种或多种单官能度或更高官能度的乙烯基不饱和化合物,这些化合物还具有酸官能团,其中一种化合物具有 P-OH 基团,例如磷酸基、膦酸基或膦酸基;(B) 2%至 50%(重量百分比)的一种或多种单官能度或更高官能度的乙烯基不饱和化合物,这些化合物不具有任何酸官能团;(C) 22.8%至 85%(重量百分比)的填充材料,包括至少一种可与组分(A)发生离子交换、中和、盐形成和/或螯合物形成反应的填充材料;(D)0.1%至 8%(重量百分比)的一种或多种引发剂和可选活化剂;(E)0.1%至 20%(重量百分比)的其他添加剂,例如改性剂,其中组分(A)相对于组分(B)的重量比(%)为 21 至 90:10 至 79.
