概括

在临床使用后,与WaveOne Gold (WOG) 和One Curve (OC) 文件相比,Reciproc Blue (RPC Blue) 单片- (NiTi) 旋转文件表现出优越的循环疲劳抵抗力. RPC蓝色文件在内牙科手术中更耐用.

科学领域:

牙周内科医院牙周内科医院牙周内科医院
牙科材料科学牙科材料科学
生物材料工程生物材料工程

背景情况:

尼克 (NiTi) 旋转文件彻底改变了内牙治疗,使得更快的根管准备和改进的灌.
尽管取得了进展,仪器分离仍然是一个重要的临床问题,影响治疗疗效和患者安全.

研究的目的:

为了比较模拟临床使用后三个单档NiTi系统:WaveOne Gold (WOG),One Curve (OC) 和Reciproc Blue (RPC Blue) 的循环疲劳抵抗.
评估重复临床使用对这些内牙仪器的耐用性和骨折抵抗性的影响.

主要方法:

120名在下牙上接受内牙治疗的患者被随机分为三组,使用WOG,OC或RPC Blue文件.
文件在第一次使用 (n=10) 和第三次使用 (n=30) 后进行了测试,以通过槽方法评估循环疲劳抵抗力.
对照组 (n=10) 测试了未使用的文件,使用双向ANOVA,Games & Howell hoc后期和Weibull可靠性分析分析数据.

主要成果:

互惠蓝 (RPC蓝) 文件在所有测试条件下表现出最高的循环疲劳耐力 (故障时间和循环数到断裂).
在第三个使用组中,OC和RPC蓝文件显示了与WOG文件相比显著更高的故障时间值 (p < .05).
在骨折后的碎片长度方面,在两组之间观察到统计学上显著的差异 (p < .05).

结论:

在临床应用后, Reciproc Blue (RPC Blue) 单档NiTi仪器显示出优异的循环疲劳抵抗力.
这些发现表明,RPC Blue文件提供了增强的耐用性,可能降低了内牙治疗中仪器分离的风险.

Fatigue

Fatigue

Fatigue occurs when materials rupture under repeated or fluctuating loads, even at stress levels far below their static breaking strength. It typically results in brittle failure, even for ductile materials. It is a critical consideration in designing machines and structural components subjected to repetitive or varying loads. The nature of these loadings can range from fluctuating loads like unbalanced pump impellers causing vibrations to repeatedly bending a thin steel rod wire back and forth...

Fatigue Strength of Concrete

Fatigue Strength of Concrete

Fatigue, in the context of materials science and engineering, refers to the weakening or failure of a material caused by repeatedly applied loads, even if these loads are below the strength limit of the material. Fatigue strength in concrete is a critical property that influences its durability and longevity. Concrete can fail in two ways due to fatigue. Static fatigue or creep rupture occurs under a constant load or one that increases slowly. The other failure mode is due to cyclical or...
