Method of manufacturing dental restorations using curable compositions including degradable macromonomers having one or more terminal acrylate or methacrylate functionality, a curing composition, a filler composition including bioactive particles of bioactive glass, bioactive glass-ceramics, calcium phosphates, calcium apatites, or mixtures thereof and optionally one or more polymerizable acrylate or methacrylate comonomers. Degradable macromonomers are manufactured from cyclic monomers with compounds having acrylate or methacrylate functionality. Depending on their use, the degradable macromonomer compositions further include one or more organic or inorganic fillers, including a calcium-based compound and/or a radiopacity-imparting agent. The compositions are particularly suitable for root canal sealants, implants, bone cements, and pulp capping materials.
使用固化组合物制造牙科修复体的方法,固化组合物包括具有一个或多个丙烯酸酯或甲基丙烯酸酯官能团末端的可降解大单体、固化组合物、填料组合物,填料组合物包括生物活性玻璃、生物活性玻璃陶瓷、磷酸钙、磷灰石钙或其混合物的生物活性颗粒,以及任选的一个或多个可聚合丙烯酸酯或甲基丙烯酸酯共聚单体。可降解大单体由具有丙烯酸酯或甲基丙烯酸酯官能团的环状单体制成。根据用途的不同,可降解大单体组合物还包括一种或多种有机或无机填料,包括钙基化合物和/或放射增容剂。这些组合物尤其适用于根管密封剂、植入物、骨水泥和牙髓封顶材料。
