摘要

目的:研究在藻酸盐印模材料中添加纳米载银磷酸锆、四针状氧化锌晶须后其物理性能的影响.方法:将2%、5%、10%比例的纳米载银磷酸锆、四针状氧化锌晶须添加到藻酸盐印模材料中,参照相关标准检测其结固时间,压应变等物理性能的变化.结果:在一定地浓度范围内,载银磷酸锆、四针状氧化锌晶须这两种无机抗菌剂对藻酸盐印模材料地物理性能均起到一定地增强作用.在相同质量比下四针状氧化锌晶须对藻酸盐印模材料物理性能的影响优于纳米载银磷酸锆.结论:纳米载银磷酸锆、四针状氧化锌晶须的添加量为5%时,对藻酸盐印模材料的性能最佳,且在此用量下,对藻酸盐印模材料物理性能的增强作用,四针状氧化锌晶须明显地优于纳米载银磷酸锆.%Objective:To study the effect of two antibacterial agents on the physics properties of alginate impression material.Methods:Silver-zirconium phosphate and T-ZnOw are added to alginate impression material respectively by 2%,5%,10%.The antibacterial ratios were tested using a method according to the Chinese and Japanese standards for testing antibacterial efficacy of antibacterial materials.Bacteria strains used testing its fixation time,the change of physical properties such as compressive strain.Results:Two kinds of inorganic antibacterial agent in certain concentration range of alginate impression material physical properties have a certain enhancement effect.With the same quality,T-ZnOw on alginate impression material physical properties is superior to the influence of nanometer zirconium phosphate carrying silver.Conclusion:Silver-zirconium phosphate and T-ZnOw in the alginate impression material in the optimum adding amount was respectively 5%,in the same case,T-ZnOw on the properties of lginate impression physics properties reinforced effect is obviously superior to silver-zirconium phosphate.
