Prepolymerizing microfilled composite resins have gained acceptance as restorative materials. However, when used as a posterior material, many of them undergo debonding of the organic filler. Such a condition has been attributed to the fact that the filler particles are held to the surface of the resin matrix primarily by mechanical means. Recently, a composite resin has been developed in which the prepolymerized organic particle is bonded chemically to the resin matrix through copolymerization. The material consists of trimethyol propane trimethacrylate, and the numerous double bonds on the surface provide a means for chemical bonding. A three-bodied wear-testing device was used in conjunction with a series of experimental trimethyol propane trimethacrylate-containing polymers, and it was shown that most of these systems offered greater resistance to wear and marginal deterioration than did conventional systems.
预聚合微填料复合树脂已被认可为修复材料。然而,当用作后牙材料时,其中许多会发生有机填料的脱粘。这种情况归因于填料颗粒主要通过机械方式附着在树脂基质表面这一事实。最近,已开发出一种复合树脂,其中预聚合有机颗粒通过共聚与树脂基质发生化学键合。该材料由三羟甲基丙烷三甲基丙烯酸酯组成,其表面的众多双键提供了化学键合的方式。一种三体磨损测试装置与一系列含三羟甲基丙烷三甲基丙烯酸酯的实验聚合物一起使用,结果表明,与传统体系相比,这些体系中的大多数对磨损和边缘劣化具有更强的抵抗力。
