Abstract

This study tested the impact of different adhesives and resin composite cements on shear bond strength (SBS) to polymethyl methacrylate (PMMA)- and composite-based CAD/CAM materials. SBS specimens were fabricated and divided into five main groups (n=30/group) subject to conditioning: 1. Monobond Plus/Heliobond (MH), 2. Visio.link (VL), 3. Ambarino P60 (AM), 4. exp. VP connect (VP), and 5. no conditioning-control group (CG). All cemented specimens using a. Clearfil SA Cement and b. Variolink II were stored in distilled water for 24 h at 37 °C. Additionally, one half of the specimens were thermocycled for 5,000 cycles (5 °C/55 °C, dwell time 20 s). SBS was measured; data were analyzed using descriptive statistics, four- and one-way ANOVA, unpaired two-sample t-test and Chi(2)-test. CAD/CAM materials without additional adhesives showed no bond to resin composite cements. Highest SBS showed VL with Variolink II on composite-based material, before and after thermocycling.

摘要

本研究测试了不同的胶粘剂和树脂复合粘接剂对聚甲基丙烯酸甲酯（PMMA）和基于复合 CAD/CAM 材料的剪切粘接强度（SBS）的影响。制备了 SBS 样本，并将其分为五个主要组（每组 30 个样本）进行处理：1. Monobond Plus/Heliobond（MH），2. Visio.link（VL），3. Ambarino P60（AM），4. exp. VP connect（VP），和 5. 无处理对照组（CG）。使用 a. Clearfil SA 水泥和 b. Variolink II 将所有粘合样本进行粘合，并在 37°C 的蒸馏水中储存 24 小时。此外，样本的一半进行了 5000 次热循环（5°C/55°C，停留时间 20 秒）。测量了 SBS；使用描述性统计、四向和单向 ANOVA、未配对的两样本 t 检验和卡方检验分析数据。没有额外胶粘剂的 CAD/CAM 材料与树脂复合粘接剂没有粘结。在热循环前后，VL 与 Variolink II 在基于复合材料的材料上显示出最高的 SBS。
