概括

这项研究比较了合剂 (SCA) 和含甲基甲酸盐 (MMA) 的基板 (MCP) 复合材料块. 一般来说,MCP表现出更高的结合强度,特别是在非喷砂表面上,尽管喷砂对某些材料提高了SCA的有效性.

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
表面化学表面化学

背景情况:

优化复合材料块和假牙之间的粘合强度对于恢复寿命至关重要.
合剂 (SCA) 和含甲基甲酸盐 (MMA) 含有甲基甲酸盐 (MCP) 的原料等原料用于增强粘附.
了解这些药物在各种复合材料块表面的比较疗效对于临床应用至关重要.

研究的目的:

评估和比较SCA和MCP在11个商业复合材料块 (CB) 上的剪接强度 (SBS).
调查喷砂表面处理对SCA和MCP的粘合效率的影响.
为了确定不同复合基板上的SCA和MCP处理的物质依赖性疗效.

主要方法:

11个商业复合材料块 (CB) 用合剂 (SCA) 或含甲基甲酸盐 (MMA) 的原料 (MCP) 进行处理.
样本在喷砂和非喷砂表面条件下进行了测试.
剪接强度 (SBS) 是使用ISO 29022划分边缘剪接强度测试来测量的.

主要成果:

在相同条件下的复合材料块中观察到SBS的显著差异.
对于大多数CBs来说,MCP处理的标本在非吹砂表面上的SBS显著高于SCA处理的标本.
在喷砂表面上,MCP在11个CB中的7个中显示出优异的SBS,而SCA在3个中更好;喷砂对SCA处理的标本更有效地增强了SBS.
与MCP治疗相比,SCA治疗的疗效更依赖于物质.

结论:

含甲基甲酸盐 (MMA) 的原料 (MCP) 通常在复合材料块上提供优越的剪接强度 (SBS),而不是合剂 (SCA),特别是在非吹砂表面上.
喷砂可以在某些复合材料上更有效地提高SCA的粘合强度,这表明表面处理和原料类型之间的相互作用效应.
虽然MCP在整体上被证明更有效,但其性能在不同的复合材料块中有所不同,这凸显了牙粘合剂协议中需要考虑特定材料的需要.

Bonding and Strength of Aggregate

Bonding and Strength of Aggregate

The bond between aggregate particles and the cement matrix is significantly influenced by the shape and surface texture of the aggregates. High-strength concretes benefit from a rougher texture, which leads to stronger bonding due to greater adhesion. Angular aggregates with larger surface areas also enhance this bond. The bonding quality, however, is complex to assess as no universally accepted test exists. Good bonding is indicated when a crushed concrete specimen shows some aggregate...

Composite Masonry Walls

Composite 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...
