概括

这项研究研究了添加多功能多面体寡合物丝素 (MA-POSS-8) 如何影响牙键强度. 5%重量的MA-POSS-8度随着时间的推移改善了蚀刻和冲洗粘合剂的粘合强度.

科学领域:

牙科材料科学牙科材料科学
聚合物化学聚合物化学
在牙科的纳米技术.

背景情况:

粘合性牙科依赖于牙基板和修复材料之间强大的纽带.
提高粘合接口的耐用性和寿命对于临床成功至关重要.
多面体寡合性丝素 (POSS) 是具有增强聚合物特性潜力的纳米粒子.

研究的目的:

为了评估将多功能多面体寡合性丝二氧化 (MA-POSS-8) 纳入蚀刻和冲洗 (ER) 和自蚀刻 (SE) 牙粘合剂的效果.
确定MA-POSS-8对长期储存水后牙剪接强度 (SBS) 和故障模式的影响.
评估MA-POSS-8作为填充剂的潜力,以提高牙粘合剂的性能.

主要方法:

在ER和SE粘合剂中透了5重%或10重%的MA-POSS-8,纯粘合剂作为对照.
牛牙样本与修改后的粘合剂和纳米混合复合材料结合在一起.
切割键强度 (SBS) 和故障模式在24小时和长达24个月的储水后被分析.

主要成果:

24个月后,5重量%的MA-POSS-8组显示,与对照组相比,ER粘合剂的SBS显著更高.
10%的MA-POSS-8度降低了ER粘合剂的SBS,并导致更有凝聚力的故障.
通用SE粘合剂的SBS随着老化而增加,无论MA-POSS-8度如何,表明其稳定性良好.

结论:

包含5%的MA-POSS-8可以增强蚀刻和冲洗粘合剂的长期牙粘合强度.
在5%的MA-POSS-8并没有对通用自蚀刻粘合剂的粘合强度产生负面影响.
MA-POSS-8作为增强牙粘合剂系统耐用性的添加剂具有前景.

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...

Chemical Bonds

Chemical Bonds

Atoms participate in a chemical bond formation to acquire a completed valence-shell electron configuration similar to that of the noble gas nearest to it in atomic number. Ionic, covalent, and metallic bonds are some of the important types of chemical bonds. Bond energy and bond length determine the strength of a chemical bond.
Types of Chemical Bonds
An ionic bond is formed due to electrostatic attraction between cations and anions. Often, the ions are formed by the transfer of electrons...
