概括
与被动方法相比,主动应用 (AA) 技术通常会提高对牙的粘合键强度. 具体的粘合剂系统表现出基于应用技术和老化变化的性能,AA被推为黄金标准.
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:
- 改善与牙基板的粘合相互作用是恢复性牙科的关键目标.
- 牙粘合剂存在各种应用技术,影响其性能.
- 了解这些技术对于优化债券强度和寿命至关重要.
研究的目的:
- 为了评估四种粘合系统 (Prime&Bond Universal,Clearfil SE Bond,OptiBond Universal,OptiBond FL) 对牙的粘合性能.
- 为了比较不同的应用模式:被动应用 (PA),主动应用 (AA),组合振动修改应用 (CVM) 和组合振动应用 (CV).
- 评估衰老 (24小时和6个月) 对键强度和材料性能的影响.
主要方法:
- 在实验室中使用80个提取的人类牙进行研究.
- 根据ISO/TS 11.405.5的微拉伸键强度和断裂模式分析.
- 进行了粘合接触角度 (CA) 和扫描电子显微镜 (SEM) 分析.
主要成果:
- 在24小时后,AA的Prime&Bond Universal (PBU) 和CVM的Clearfil SE债券 (CSE) 显示出更高的债券强度.
- 6个月后,CSE,PBU和OptiBond Universal (OBU) 显示出依赖于技术的债券强度变化.
- 积极应用 (AA) 显示了较低的接触角度,并且在测试的粘合剂中显示了树脂透到牙管道.
结论:
- 粘合材料和应用技术都会显著影响牙粘合强度.

01:12Bonding and Strength of Aggregate
201
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...

01:17Mortar Properties
131
Mortar properties encompass a range of characteristics crucial for construction and masonry work, including workability, water retention, bond strength, durability, compressive strength, volume change, and appearance. Workability refers to mortar's ability to be easily applied and manipulated without sagging or falling off surfaces, which is important for efficient masonry unit placement and alignment. Water retention is essential to prevent the mortar from losing moisture too quickly to...
