目得：在义齿基托树脂上添加阴离子电荷已被证明可以抑制白色念珠菌的粘附并促进唾液防御分子的吸附。本研究的目的是评价一种用于义齿制作的改性义齿基托树脂的物理性能。材料与方法：以热聚合树脂Lucitone 199制成的试件作为对照组。两个实验组E-10和E-20分别有10%和20%的单体被实验性含磷酸酯单体取代。进行抗弯强度和模量、吸水性、溶解度和颜色稳定性试验，以确保符合ADA质量标准12。还评估了水向树脂和树脂中的扩散系数。方差分析和Scheffe检验进行统计显着性。结果：有一个整体下降，在所有性能与实验磷酸盐化合物的加入。然而，E-10以及对照品的弯曲强度和模量、吸水性和溶解度均在ADA质量标准范围内。三组的扩散系数有显著性差异（p < 0.05）。染色和颜色标本显示无显着性差异（P > 0.05）之间的三groups.CONCLUSIONS：在本研究的限制，在10%的磷酸盐义齿基托树脂的物理性能应该是适合义齿制作的基础上评估的属性。
PURPOSE: The addition of anionic charge on denture base resins has been shown to inhibit Candida albicans adhesion and to facilitate adsorption of salivary defense molecules. The aim of this study was to evaluate the physical properties of a modified denture base resin for denture fabrication.MATERIALS AND METHODS: Specimens made from heat polymerizing resin Lucitone 199 were used as the control group. The two experimental groups, E-10 and E-20, had 10% and 20%, respectively, of the monomer substituted with an experimental phosphate-containing monomer. Flexural strength and modulus, water sorption, solubility, and color stability tests were conducted to ensure compliance with ADA specification No. 12. Water diffusion coefficient into the resins and stainability were also assessed. ANOVA and Scheffe tests were performed for statistical significance.RESULTS: There was an overall decline in all properties with the addition of the experimental phosphate compound. The flexural strength and modulus, water sorption and solubility for E-10, as well as the control were, however, within the ADA specifications. The diffusion coefficients were significantly different (p < 0.05) for the three groups. Staining and color specimens showed no significant difference (p > 0.05) among the three groups.CONCLUSIONS: Within the limitations of this study, the physical properties of the phosphate denture base resin at 10% should be suitable for denture fabrication based on the properties assessed.
