概括
活性粘合技术通常比对大多数通用粘合剂的修改三层应用 (MTLA) 对牙产生更高的粘合强度. 然而,在六个月的时间里,粘合强度的耐用性因材料和应用方法而异.
科学领域:
- 牙科材料科学 牙科材料科学
- 粘合式牙科 粘合式牙科
- 生物材料是一种生物材料.
背景情况:
- 优化粘合剂应用技术对于实现牙修复材料和牙结构之间持久的纽带至关重要.
- 修改的三层应用 (MTLA) 和活性粘合技术是提高粘合性能的策略.
- 了解这些技术对各种粘合剂系统的影响对于临床成功至关重要.
研究的目的:
- 评估MTLA策略 (主动-被动-被动,主动-主动-被动,主动-主动-主动) 与单个主动应用 (A) 对四种粘合系统对牙粘合强度的影响.
- 在24小时和6个月的老化后,评估结合强度和接口形态.
- 为了确定结合性能是否依赖于材料.
主要方法:
- 四种粘合系统 (Prime&Bond Universal,OptiBond Universal,OptiBond FL,Clearfil SE) 进行了测试. 这些系统包括:
- 使用单个活性 (A) 和三种MTLA技术 (APP,AAP,AAA) 应用粘合剂.
- 在24小时和6个月后测量了微拉伸键强度;通过SEM检查了接口形态.
主要成果:
- 在24小时时,与MTLA技术相比,单一活跃应用 (A) 显示了四种粘合剂中的三种 (OptiBond FL,OptiBond Universal,Prime&Bond Universal) 的键强度明显更高.
- 六个月后,A技术总体上保持了优越的债券强度,OptiBond FL显示了A和AAA技术的可比结果.
- 只有Prime&Bond Universal在所有应用技术中表现出随着时间的推移的一致的粘合强度;在MTLA中观察到更厚的粘合层.
结论:
- 单次活性应用技术通常为大多数测试的通用粘合剂提供了与MTLA相比,对牙的更高的即时和长期结合强度.
- 粘合性能和耐久性取决于粘合剂系统,并受应用技术的影响.
- 对树脂标签的形成和接口的完整性进行进一步的研究,对于像OptiBond FL.这样的特定粘合剂系统是有必要的.

Bonding and Strength of Aggregate
200
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
16.6K
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...
