概括

与干燥方法相比,乙醇湿粘合降低了正牙支架剪切粘合强度. 然而,乙醇为湿结合提供了MIP的经济有效的替代品,保持了足够的结合强度.

科学领域:

ортодонтика和牙科材料科学牙科和牙科材料科学

背景情况:

ортодонтика支架粘合对于治疗成功至关重要.
湿结合技术可能会损害剪接结合强度 (SBS).
探索像乙醇这样的替代粘合剂是必不可少的.

研究的目的:

为了评估乙醇湿结合对正统牙科支架剪切结合强度的影响.
为了比较乙醇湿结合与传统和MIP (甲基化物聚合) 方法.

主要方法:

90个前牙被分为六组:传统的干湿,MIP干湿和乙醇干湿.
测量了剪接强度 (SBS) 和粘附残留指数 (ARI) 的得分.
对获得的SBS和ARI数据进行了统计分析.

主要成果:

传统的干粘合产生了最高的SBS,而传统的湿粘合显示出最小的SBS.
乙醇湿结合显示SBS明显低于MIP湿结合,但高于传统湿结合.
在湿MIP和乙醇组中,ARI得分显示出比粘合剂故障更具凝聚力.

结论:

乙醇湿粘合是一种可行的,成本效益高的替代方案,以MIP为正牙支架粘合.
虽然湿结合通常会减少SBS,但以乙醇为基础的方法保持了临床上可接受的结合强度.

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...
