概括
与延迟准备的连续波凝结 (CWC) 相比,使用单 (SC) 堵塞的即时后空间准备显示出优越的纤维后键强度. 这一发现影响了内牙后安置策略.
科学领域:
- 牙周内科医院 牙周内科医院 牙周内科医院
- 牙科材料科学 牙科材料科学
背景情况:
- 纤维柱被广泛用于恢复经过内牙治疗的牙.
- 空间后准备的时间和封闭技术可以影响纤维柱的粘合强度.
研究的目的:
- 评估即时与延迟后空间准备对纤维后推出键强度 (PBS) 的影响.
- 为了比较两个封闭技术:单形 (SC) 和连续波凝结 (CWC).
主要方法:
- 四十八个人类前被分为四组,基于封闭技术 (SC,CWC) 和后空间准备时间 (即时,延迟).
- 扫描电子显微镜 (SEM) 评估了涂抹层的去除,微型计算机断层扫描 (CT) 评估了空虚体积.
- 推出的结合强度测试是在从顶,中间和宫区域的根切片上进行的.
主要成果:
- 与延迟准备的CWC相比,立即后空间准备的单 (SC) 堵塞显示出更高的结合强度.
- 在SC直接组中,SEM显示了部分涂抹层的去除和可见的牙管.
- 两组之间没有发现空虚体积的显著差异.
结论:
- 与SC封闭的即时后空间准备提供了优越的结合强度,用于纤维柱到内牙.
- 这些发现表明,SC封闭和即时准备的结合可能会增强后保留.

01:12Bonding and Strength of Aggregate
462
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...

01:15Posttensioned Masonry Walls
454
Post-tensioned masonry walls use high-strength steel rods or flexible tendons to enhance the strength and efficiency of masonry structures. These elements are securely anchored to the foundation and extend vertically either within the cores of the masonry units or between the masonry wythes. The construction process involves building the wall with these tensioning elements in place and allowing the mortar to fully cure.
Following the curing process, the tensioning begins. Steel rods are...
