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

两种类型的单体，不同的乙氧基化物的数量和预期具有较低的粘度和收缩率，被用来使实验光固化牙科复合材料。研究了其稠度、固化收缩率和机械强度。复合材料的稠度随乙醇单体含量的增加而降低。由等量的两种单体的混合物制成的复合材料显示出与常规的bis-GMA基复合材料相似的强度。

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.
