概括

在这个系统性审查中,单立式石完整门假肢显示出高生存率 (99%) 和植入物寿命 (100%). 然而,在14%的案例中出现了技术并发症,而面板设计的发生率更高.

科学领域:

牙科植入物学牙科植入物学
牙修复牙修复牙修复牙修复牙修复
生物材料科学生物材料科学

背景情况:

有限证据表明,单立体石对完整的形植入物支持假肢的长期结果有限.
数据的异质性需要对临床可预测性评估进行全面的系统审查.

研究的目的:

系统地评估单体石完整门植入物支持假肢的生存率和整体性能.
综合现有关于并发症率和临床可预测性的证据.

主要方法:

按照PRISMA指南进行的13项研究 (2841个假肢,3940个植入物) 的系统审查和元分析.
随机效应模型用于聚合比例分析;对并发症的子组分析.
使用ROBINS-I评估的偏差风险;使用GRADE对证据的确定性进行分级.

主要成果:

整体假肢存活率为99% (95% CI: 97%-100%),植入物寿命为100% (95% CI: 99%-100%).
聚合技术并发症率为14% (95%CI:4%-27%),在面 (27%) 和单体 (1%-3%) 设计中显著高.
大多数研究都有中度至严重的偏差风险;GRADE评估表明证据的确定性较低.

结论:

单立体石完整的门假肢表现出高的累积存活率和植入长寿.
在报告的随访期内,观察到技术和生物并发症的低率.
由于目前证据的方法限制和异质性,需要进一步进行高质量的研究.

Spanning Openings in Brick Walls

Spanning Openings in Brick Walls

In brick wall construction, supporting structures are crucial for openings like windows and doors to maintain the integrity and support the weight of the wall above. These supports include lintels, corbels, and arches, each serving specific structural purposes.
Lintels are primary supports used to span openings and can be crafted from materials such as reinforced concrete, steel-reinforced brick masonry, or simple steel angles. These are straightforward to install and are typically concealed...

Non-destructive Tests for Concrete Strength

Non-destructive Tests for Concrete Strength

The rebound hammer test, also known as the Schmidt hammer test, is a non-destructive technique for evaluating the hardness of concrete and, indirectly, the strength of concrete. It operates on the principle that the rebound of a spring-driven mass from a concrete surface correlates to the surface's hardness. The device comprises a mass within a tubular housing, a spring mechanism, and a plunger that strikes the concrete. Upon release, the energy imparted to the mass by the spring causes it to...
