Abstract

OBJECTIVE

The objective of this study was to evaluate the influence of adhesives with different 10-MDP concentrations on the shear bond strength of a resin cement to zirconia.

METHODS AND MATERIALS

Six experimental adhesives were prepared with the following composition: camphorquinone, 1,2-diaminobenzene, butylhydroxytoluene, diphenyliodonium hexafluorophosphate, 2-hydroxyethyl methacrylate triethylene glycol dimethacrylate, ethoxylated bisphenol A glycol dimethacrylate, urethane dimethacrylate, bisphenol A diglycidyl methacrylate, and ethanol. The 10-methacryloyloxydecyl dihydrogen phosphate (10-MDP) monomer was added at 0wt%, 3wt%, 6wt%, 9wt%, 12wt%, or 15wt%. Three commercially available adhesives were evaluated: Single Bond Universal, Single Bond 2, and Signum Zirconia Bond. Resin cement cylinders made with RelyX Ultimate were bonded to yttria-stabilized tetragonal zirconia polycrystal with one of the evaluated adhesives and were subjected to the shear bond strength evaluation. Failure modes were analyzed with a stereoscopic loupe. Statistical analyses were performed with one-way analysis of variance and the Tukey's Honestly Significant Difference test (α=0.05). Pearson's was used to correlate the percentage of 10-MDP in the experimental adhesives and shear bond strength.

RESULTS

There were significant differences between adhesives (p<0.00001). The highest shear bond strength values were obtained with the Signum Zirconia Bond and Single Bond Universal. Single Bond 2 showed the lowest values. There were no differences between experimental adhesives. All groups showed adhesives failures. A nonlinear correlation was found between bond strength and percentage of 10-MDP in experimental adhesives (r=0.872).

CONCLUSIONS

The commercially available adhesives indicated for bonding to zirconia showed the highest bonding values.

摘要

目的

本研究的目的是评估不同10 - MDP浓度的粘接剂对树脂水门汀与氧化锆之间剪切粘接强度的影响。

方法和材料

制备六种实验性粘接剂，其组成如下：樟脑醌、1,2 - 二氨基苯、丁基羟基甲苯、六氟磷酸二苯基碘鎓、甲基丙烯酸2 - 羟乙酯三乙二醇二甲基丙烯酸酯、乙氧基化双酚A乙二醇二甲基丙烯酸酯、聚氨酯二甲基丙烯酸酯、双酚A二缩水甘油甲基丙烯酸酯和乙醇。10 - 甲基丙烯酰氧基癸基磷酸二氢酯（10 - MDP）单体的添加量分别为0wt%、3wt%、6wt%、9wt%、12wt%或15wt%。评估了三种市售粘接剂：通用型单键粘接剂、单键粘接剂2和氧化锆专用型Signum粘接剂。用RelyX Ultimate制作的树脂水门汀圆柱体用其中一种评估的粘接剂与氧化钇稳定的四方多晶氧化锆进行粘接，并进行剪切粘接强度评估。用立体放大镜分析失效模式。采用单因素方差分析和Tukey's 真实显著差异检验（α = 0.05）进行统计分析。用Pearson's方法关联实验性粘接剂中10 - MDP的百分比与剪切粘接强度。

结果

粘接剂之间存在显著差异（p < 0.00001）。氧化锆专用型Signum粘接剂和通用型单键粘接剂获得了最高的剪切粘接强度值。单键粘接剂2显示出最低的值。实验性粘接剂之间没有差异。所有组均显示粘接剂失效。在实验性粘接剂中，粘接强度与10 - MDP的百分比之间发现非线性相关性（r = 0.872）。
