摘　　要：目的:研究添加纳米载银磷酸锆和载银纳米二氧化钛对义齿软衬材料机械性能的影响。方法:将纳米载银磷酸锆和载银纳米二氧化钛分别按2%、5%、10%和1%、3%、5%的比例添加于Silagum软衬材料中,按国家相关标准检测其粘结强度、拉伸强度和邵氏硬度的变化。结果:两种纳米无机抗菌剂在一定浓度范围内对软衬材料的机械性能均有一定的增强作用。当纳米载银磷酸锆与载银纳米二氧化钛的添加质量分数分别为5%和3%时,软衬材料的机械性能综合体现较好。结论:纳米载银磷酸锆与载银纳米二氧化钛在软衬材料中的最佳添加量分别为5%和3%,且在此量下,载银纳米二氧化钛对软衬材料机械性能的增强作用明显优于纳米载银磷酸锆。Objective：To study the effect of antibacterial agents on the mechanical function of soft denture liners. Methods：Silver-zirconium phosphate and Nano.Ag-TiO2respectively by 2%,5%,10% and 1%,3%,5% are added to Silagum soft denture liners.The bond strength,the tensile strength and the Shore-A hardness were tested,according to national standards.Results：Two different antibacterial agents in a certain range of concentration on mechanical function of soft denture liners have certain enhancement effect.Silver-zirconium phosphate and Nano. Ag-TiO2content were 5% and 3%,the mechanical properties of soft denture liners synthesis manifests better. Conclusion：Silver-zirconium phosphate and Nano.Ag-TiO2in the soft denture liners in the optimum adding amount was respectively 5%and 3%.In this case,Nano.Ag-TiO2on the properties of soft denture liners reinforced effect is obviously superior to silver-zirconium phosphate.
