本研究评估了超声和酸洗对树脂骨水泥与CAD/CAM树脂块粘合的影响。将两种树脂粘固剂PANAVIA V5（PV 5）或PANAVIA SA CEMENT HANDMIX（PSA）中的一种粘固到24个CAD/CAM块（KATANA AVENCIA BLOCK）中的一个上。每个骨水泥组又分为4个亚组：不清洗（Ctl）、超声清洗（Uc）、酸洗（Ac）和Uc+Ac。微拉伸粘结强度（亩TBS）立即和1，3，和6个月后，水存储。通过扫描电子显微镜分析每次处理后的块表面。方差分析显示，参数“表面处理”（p
The present study assessed the effect of ultrasonic and acid cleaning on resin cement bonding to CAD/CAM resin blocks. One of two resin cements, PANAVIA V5 (PV5) or PANAVIA SA CEMENT HANDMIX (PSA), were bonded to one of 24 CAD/CAM blocks (KATANA AVENCIA BLOCK). Each cement group was divided into four subgroups: no cleaning (Ctl); ultrasonic cleaning (Uc), acid cleaning (Ac) and Uc+Ac. Micro-tensile bond strengths (mu TBSs) were measured immediately and 1, 3, and 6 months after water storage. Block surfaces after each treatment were analyzed by scanning electron microscopy. Analysis of variance revealed a statistically significant effect for the parameters 'surface treatment' (p
