Development of dental composite resin utilizing novel low-shrinking and low-viscous monomer mixtures

采用两种不同数量的乙氧基单体，制备了具有较低粘度和收缩率的实验性光固化牙科复合材料。对其稠度、固化收缩率和机械强度进行了研究。随着环氧单体含量的增加，复合材料的稠度降低。两种单体的等量混合制备的复合材料强度与常规双gma基复合材料相近。

Two types of monomer, differ in number of ethoxides and expected to possess lower viscosity and shrinkage, were used to make experimental light cure dental composites. The consistency, curing shrinkage and mechanical strength was investigated. The consistency of composites was decreased with the increase of more ethoxide monomer content. The composite made by the mixture in equal amount of two monomers showed similar strength to conventional bis-GMA base composites.
