概括

与标准支架相比,一个实验性的牙科支架设计提高了90%以上的粘合转换. 虽然债券强度没有显著差异,但增强的转换表明了改善长期支架保留的潜力.

科学领域:

生物材料科学生物材料科学
牙科材料牙科材料
ортодонтическая技术 ортодонтическая 技术 ортодонтическая 技术

背景情况:

ортодонтика支架的解仍然是一个临床的挑战.
提高粘合树脂性能对于可靠的支架固定至关重要.
目前的支架设计可能会限制光线的透,影响粘合剂固化.

研究的目的:

为了评估一个实验式支架设计的质粘合能力.
为了评估正义牙粘合树脂的转换度 (DC),使用新型支架.
为了比较实验和标准括号之间的剪接强度 (SBS) 和粘接残留指数 (ARI).

主要方法:

13个牛牙被用于粘合实验.
一个具有中央半透明区域的实验支架 (点支架,SB) 与标准支架 (CB) 相比较.
通过拉曼光谱分析了剪接强度 (SBS),粘合残留指数 (ARI) 和转换度 (DC).

主要成果:

现货支架 (SB) 组显示出高于控制支架 (CB) 组 (8.77 MPa) 的平均SBS (10.33 MPa),但这在统计学上并不显著 (p=0.376).
两组均平均ARI分数为1,表明类似的粘合剂残留物.
拉曼光谱检测显示,SB组 (49.3%) 与CB组 (25.9%) 相比,SB组的DC显著更高.

结论:

实验式支架设计显著增加了正统牙粘合剂的转换程度.
尽管增强了粘合剂转换,但实验支架没有产生统计学上显著的剪接强度增加.
这些发现表明,实验设计可能会改善粘合物聚合,这可能会影响临床性能.

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...
