摘要/Abstract

摘要： 目的研究义齿基托树脂表面抗菌涂层对基托吸水性和溶解性以及单体渗出的影响。方法根据YY 0270-2003 标准,测量4种基托树脂涂膜前、后的吸水值和溶解值,应用索氏提取法测量固化后基托树脂的交联度;利用气相色谱法测量基托树脂涂膜前、后的单体渗出量。采用SPSS17.0软件包对数据进行统计学分析。结果具有抗菌涂层的基托材料的吸水值、溶解值和单体渗出量明显减少。4种材料中,贺利氏树脂的交联度最高,日进和山八树脂次之,新世纪树脂最低。结论义齿基托树脂的吸水值、交联度和单体渗出量之间存在一定联系,即交联度较大时,吸水值减少,甲基丙烯酸单体渗出量也相应降低。抗菌涂层可以提高树脂基托的综合性能。

Abstract: PURPOSE: To determine the influence of denture base resins coated with antibacterial coating on water sorption, solubility and monomer elution. METHODS: The values of water sorption and solubility were measured according to YY 0270-2003 and gas chromatography was used to examine the leachability of 4 commercially available heat-cured acrylic resins between experimental group and control group. Degree of crosslinking of the experimental heat-cured acrylic denture bases were measured by soxhlet extraction method. The data was analyzed by 17.0 software package. RESULTS: The values of water sorption, solubility and monomer elution of experimental group were lower compared to the control group. Degree of crosslinking of Heraeus reins was the highest among the experimental heat-cured acrylic denture bases. CONCLUSIONS: There is a same trend among water sorption, degree of crosslinking and the monomer elution. When the degree of crosslinking increases, the values of water sorption and monomer elution decrease. Antibacterial coating can improve the comprehensive properties of the denture base resins.
