Abstract

Fiber-reinforced composites have recently been advocated as an alternative to fixed metal framework prostheses. The aim of this study was to evaluate the effect of glass-fiber reinforcement on the flexural strength of different resin composites. The tested composites were X-tra fil, Filtek Z350 XT Flow and Filtek Z350 XT commercially available and reinforced with glass-fiber. Six groups of bars specimens (2?×?2?×?20?mm) were prepared (n?=?10). The measurement of flexural strength of the resin composites was carried out by the three-point bending test. Data were subjected to ANOVA and post hoc Tukey’s tests (α?=?0.05). The flexural strength of all composites was improved when combined with glass fiber. The bulk-fill X-tra fil composite (133.53?MPa) was the strongest fiber-reinforced material. Clinically, fiber reinforcement should be employed in extensive restorations to provide increased flexural strength.

玻璃纤维增强对不同树脂复合材料抗弯强度的影响

纤维增强复合材料最近被提倡作为固定金属框架假体的替代品。本研究的目的是评价玻璃纤维增强对不同树脂复合材料抗弯强度的影响。测试的复合材料为X-tra fil、Filtek Z350 XT Flow和Filtek Z350 XT，均采用玻璃纤维增强。共制备6组棒材样品(n = 10)，尺寸为2 × 2 × 20 × mm。采用三点弯曲试验对树脂复合材料的抗弯强度进行了测试。数据进行方差分析和事后Tukey检验(α?=?0.05)。与玻璃纤维结合后，复合材料的抗弯强度均有提高。体积填充X-tra -fil复合材料(133.53 MPa)是最强的纤维增强材料。临床上，纤维增强应用于广泛的修复，以提供增加的抗弯强度。
