Abstract

UNLABELLED

Background and aims. Polymethyl methacrylate (PMMA) is widely used for the fabrication of removable prostheses. Silver nano-particles (AgNps) have been added to PMMA because of their antimicrobial properties, but their effect on the mechanical properties of PMMA is unknown. The aim of this study was to investigate the effects of AgNps on the tensile strength of PMMA. Materials and methods. For this study, 12 specimens were prepared and divided into two groups. Group 1 included PMMA without AgNps and group 2 included PMMA mixed with 5 wt% of AgNps. Tensile strength of the specimens was measured by Zwick Z100 apparatus. Statistical analysis was carried out by SPSS using t-test. Statistical significance was defined at P<0.05. Results. This study showed that the mean tensile strength of PMMA in group 2 was significantly lower than that in group 1. Therefore, the tensile strength decreased significantly after incorporation of silver nano-particles.

CONCLUSION

Within the limitations of this study, tensile strength of acrylic resin specimens was influenced by silver nano-particles.

摘要

未标注

背景与目的。聚甲基丙烯酸甲酯（PMMA）广泛用于制作可摘义齿。由于银纳米颗粒（AgNps）具有抗菌特性，已将其添加到PMMA中，但其对PMMA机械性能的影响尚不清楚。本研究的目的是探讨AgNps对PMMA拉伸强度的影响。材料与方法。本研究制备了12个标本并分为两组。第1组包括不含AgNps的PMMA，第2组包括混合了5 wt% AgNps的PMMA。标本的拉伸强度通过Zwick Z100仪器测量。使用SPSS通过t检验进行统计分析。统计学显著性定义为P<0.05。结果。本研究表明，第2组中PMMA的平均拉伸强度显著低于第1组。因此，加入银纳米颗粒后拉伸强度显著降低。

结论

在本研究的局限性范围内，丙烯酸树脂标本的拉伸强度受银纳米颗粒影响。
