概括

将含原料的原料两次应用到喷砂的体表面,可以最大限度地提高树脂水泥的剪接强度 (SBS). 这种优化对于耐用体修复至关重要,不包括M&C Primer集团.

科学领域:

牙科材料科学牙科材料科学
生物材料工程生物材料工程
粘合式牙科粘合式牙科

背景情况:

基于的牙假体提供了出色的美学和机械性能.
在和树脂水泥之间实现持久的纽带对于长期的修复成功至关重要.
含酸盐的原料通常用于增强对石表面的附着性.

研究的目的:

为了研究含有酸盐的原料应用的最佳数量,以最大限度地提高石和树脂水泥之间的剪接强度 (SBS).
为了评估不同类型的原料和应用频率对子水泥结合耐久性的影响.

主要方法:

315个体样本进行了沙吹,并根据原料类型 (CLEARFIL CERAMIC PRIMER,PANAVIA V5牙原料,M&C PRIMER,Monobond N,Z-PRIME plus) 和应用编号 (1-4) 分成组.
用树脂水泥粘合样本,并使用通用测试机器测量SBS.
使用立体显微镜分析了解锁的表面,用双向ANOVA统计分析了数据.

主要成果:

两种含酸盐的原料应用通常会在大多数原料组中产生最高的SBS.
在PANAVIA V5牙膏,Monobond N和Z-PRIME plus的两个应用程序中观察到SBS的显著增加.
在第二次应用时,M&C Primer组显示SBS显著下降,所有故障都是粘合剂.

结论:

为了在合金-树脂水泥接口上获得最佳的剪接强度,喷砂合金表面应两次应用含酸盐的原料.
M&C Primer是一个例外,因为它的第二次应用降低了债券的强度.
这些发现为寻求通过改进的凝固协议提高体修复寿命的临床医生提供了关键指导.

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...
