牙修复牙修复牙修复牙修复牙修复

背景情况:

固定在水泥上的修复在假牙方面至关重要.
和是皇冠和支柱的常见材料.
树脂水泥的选择会影响修复的寿命和结合的耐用性.

研究的目的:

评估各种树脂水泥的剪接强度 (SBS) 和耐久性.
为了比较自蚀刻,自粘和未填充的树脂水泥.
评估储存条件 (储水,热循环) 对结合强度的影响.

主要方法:

测试了6个树脂水泥组 (三个自蚀刻,两个自粘,一个未填充)
与圆柱相结合的立方体经过24小时的储水或5000/10,000次热循环.
使用通用测试机测量剪接强度 (SBS),然后进行故障模式分析.

主要成果:

储存条件和粘合剂显著影响了SBS (p < 0.05),除了IS和GMP (p > 0.05).
AI和RU水泥在10000次热循环后显示SBS降低;SB和GM显示SBS增加.
在24小时的水储存后,GM和GMP在SBS中表现出显著的差异,但在热循环后却没有.

结论:

树脂水泥类型和储存条件显著影响SBS.
使用HEMA和10-MDP的结合系统初始强度很高,但在热循环后降解.
在测试条件下,IS,GM和GMP水泥表现出稳定的结合耐久性.

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...
