摘　　要：齿科修复用复合树脂是目前牙体缺损常用的修复材料。研究发现,树脂残余单体对材料的机械、化学及生物学性能具有不可忽视的影响。本文阐述了牙科复合树脂残留单体的危害,分析了树脂基质、无机填料的类型、含量,以及引发体系、光照、二期处理等因素对复合树脂单体转化率的影响,讨论了提高单体转化率的有效措施和方法,指出了复合树脂发展方向,为研制更为理想的复合树脂和临床应用提供一定的理论依据。Dental composite resin is a kind of material which has been widely used in dental restoration.Research has found that the influence of residual monomer on the material mechanical,chemical and biological properties cannot be ignored.This paper elaborates these harms of residual monomers.The effects of resin matrix,inorganic filler and initiating system,illumination,secondarily treatment on the degree of conversion were also analyzed.The paper also discusses the effective measures to increase the conversion,and offers theoretical basis for the clinical application and development of composite resin.
