Abstract

A methylmethacrylate-free denture base polymer (Eclipse) in comparison to a conventional denture base polymer (Palapress vario) was evaluated after water saturation and Stick glass fibre reinforcement. The data were analysed with ANOVA at a = 0.05. Water-storage caused a decrease in the flexural strength and stiffness of the materials (p > 0.05). Conventional denture base material with fibre reinforcement gave highest flexural strength (201.1 MPa) compared to fibre reinforced Eclipse (79.1 MPa) (p < 0.05). Water sorption after 76 days was 2.08% (Palapress vario) and 1.55% (Eclipse). Fibre-reinforcement of methylmethacrylate-free material was not as successful as conventional denture base and needs to be further optimized.

摘要

在水饱和及粘贴玻璃纤维增强后，对一种不含甲基丙烯酸甲酯的义齿基托聚合物（Eclipse）与传统义齿基托聚合物（Palapress vario）进行了评估。数据采用方差分析，显著性水平α = 0.05。水储存导致材料的弯曲强度和刚度降低（p > 0.05）。与纤维增强的Eclipse（79.1 MPa）相比，纤维增强的传统义齿基托材料具有最高的弯曲强度（201.1 MPa）（p < 0.05）。76天后的吸水率分别为2.08%（Palapress vario）和1.55%（Eclipse）。不含甲基丙烯酸甲酯材料的纤维增强不如传统义齿基托成功，需要进一步优化。
