■聚甲基丙烯酸甲酯(PMMA)是一种常用的义齿基托材料,但是在功能负荷下对骨折的敏感性仍然是一个挑战。
■这项初步筛选研究旨在研究丝胶和丝心蛋白在PMMA义齿基托材料中作为增强剂的潜力。
■加入0.01%丝胶的PMMA的弯曲和冲击强度,丝胶和丝心蛋白各0.01%,进行了评估。对照组由PMMA组成,不含任何添加剂。测量破坏样品所需的最大载荷和能量。使用单向ANOVA检验和ScheffePostHoc检验进行统计分析,以比较亚组之间的平均值。
■结果表明,添加丝胶蛋白和丝心蛋白后,PMMA的弯曲和冲击强度得到了显着改善。含0.01%丝胶的亚组,丝胶和丝心蛋白各0.01%,与对照组相比,负荷和能量测量的平均值更高。统计分析证实了这些发现的意义。
■向PMMA义齿基树脂材料中添加0.01%的丝胶和丝心蛋白各自0.01%的丝胶和丝心蛋白显着增加了其弯曲和冲击强度。这些初步发现表明丝胶和丝心蛋白作为PMMA义齿基托材料中有效增强剂的潜力,从而增强它们的生物力学特性。
UNASSIGNED: Polymethyl methacrylate (PMMA) is a commonly used denture base material, but susceptibility to fracture under functional loading remains a challenge.
UNASSIGNED: This preliminary screening study aims to investigate the potential of sericin and
fibroin as reinforcing agents in the PMMA denture base material.
UNASSIGNED: The flexural and impact strengths of PMMA incorporated with 0.01% sericin, and 0.01% each of sericin and
fibroin, were evaluated. The control group consisted of PMMA without any additives. The maximum load and energy required to break the samples were measured. Statistical analysis was performed using one-way ANOVA test and Scheffe Post Hoc tests to compare mean values between subgroups.
UNASSIGNED: The results indicated significant improvement in the flexural and impact strengths of PMMA with the addition of sericin and
fibroin. The subgroups with 0.01% sericin, and 0.01% each of sericin and
fibroin, demonstrated higher mean values in load and energy measurements compared to the control group. The statistical analysis confirmed the significance of these findings.
UNASSIGNED: The addition of 0.01% sericin and 0.01% each of sericin and fibroin to PMMA denture-based resin material significantly increases its flexural and impact strengths. These preliminary findings suggest the potential of sericin and
fibroin as effective reinforcing agents in PMMA denture base materials, thereby enhancing their biomechanical properties.
