概括
实现自然牙美学需要匹配修复材料的颜色和半透明度. 这项研究发现,相同的树脂基复合材料 (RBC) 的不同分层配方之间或不同RBC之间在颜色或半透明度方面没有显著的兼容性.
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:
- 自然外观的牙修复取决于将修复材料的特性与天然牙结构相匹配.
- 颜色和半透明度是美学修复牙的关键因素.
研究的目的:
- 为了评估不同商业树脂基复合材料 (RBC) 之间的颜色和半透明度兼容性.
- 评估不同RBC系统内和不同RBC系统之间的各种分层配方之间的兼容性.
主要方法:
- 从三个RBC (ESS,BEG,IPS) 中准备了60个圆盘样本 (1毫米厚).
- 使用四种分层配方 (乳,牙,不透明色调) 来创建单层,双层和三层样本.
- 测量了颜色 (CIE L*a*b*C*h°) 和半透明度 (RTP00);分析了颜色 (ΔE00) 和半透明度 (ΔRTP00) 的差异.
主要成果:
- 在所有红细胞和配方中发现了颜色和半透明度的显著差异 (p < 0.001).
- 透光度根据使用的RBC和分层配方有显著的变化.
- 材料之间的颜色差异比每个配方内的半透明度差异更明显.
结论:
- 在相同红细胞的不同分层配方之间没有发现显著的颜色或半透明度兼容性.
- 在使用不同复合材料品牌时,类似的分层配方之间也缺乏兼容性.
- 为了达到可预测的美学效果,需要仔细选择材料,并考虑分层技术.

01:18Composite Masonry Walls

Composite masonry walls combine multiple wythes of the same or different masonry materials to create a unified structure. These walls feature wythes that are bonded together either through mortar-filled collar joints, grouted spaces, or more commonly, with rigid metal ties and reinforcements, with the use of masonry header units being rare. Metal ties are preferred because they effectively minimize water penetration, as these walls primarily absorb moisture and then release it into the...

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...
