概括

与传统复合材料相比,纤维增强复合材料 (FRCs) 显著提高了与传统复合材料相比,具有大 mesio-occluso-distal (MOD) 腔的牙的骨折抵抗力. 埃弗斯蒂克玻璃纤维表现出最高的断裂阻力,为后部修复提供了更好的耐用性.

科学领域:

牙科材料科学牙科材料科学
生物材料工程生物材料工程
恢复性牙科恢复性牙科

背景情况:

重新修复大后牙,而后牙有间隙,则存在骨折的风险.
传统的纳米混合复合材料可能在闭塞负载下缺乏足够的尖端增强.
纤维增强复合材料 (FRC) 具有改善机械性能和应力分布的潜力.

研究的目的:

用不同的FRC系统和常规复合树脂恢复的MOD腔与下牙的骨折阻力进行比较.
评估FRCs在加强弱化牙结构以防止骨折方面的有效性.

主要方法:

在40个人类下牙中准备了标准化的MOD腔.
使用纳米混合复合材料 (控制) 或纳米混合复合材料与FibraFill Dentin,Ribbond聚乙烯纤维或EverStick玻璃纤维进行了恢复.
使用通用测试机器测试骨折阻力,直到故障.

主要成果:

所有FRC组均表现出比对照组 (仅纳米混合复合材料) 高的平均断裂阻力.
埃弗斯蒂克 (2759.5N) 的骨折阻力明显高于对照组 (1655.3N).
FibraFill Dentin (2371.1 N) 和Ribbond (2057 N) 也改善了骨折阻力,尽管与对照组或彼此相比并不总是显著.

结论:

与传统复合材料相比,FRC显著提高了具有大MOD腔的牙的断裂阻力.
在经过测试的材料中,EverStick玻璃纤维提供了最高的断裂阻力.
FRCs代表了一种有前途的方法来加强严重损坏的后牙.

Fiber Reinforced Concrete

Fiber Reinforced Concrete

Fiber-reinforced concrete significantly enhances the structural and nonstructural properties of traditional concrete by incorporating fibers like steel, glass, and polymers. These fibers, varying from natural ones such as sisal and cellulose to manufactured ones like polypropylene and Kevlar, are mixed into hydraulic cement with aggregates. Steel fibers, often preferred for their robustness, contribute to improved ductility, toughness, and post-cracking performance. The concrete is classified...

Fractures: Bone Repair

Fractures: Bone Repair

Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
