Abstract

Purpose

The primary objective of this study was to determine which single-shade composite surface yielded clinically acceptable shear bond strength (SBS) to metal orthodontics brackets. The secondary objectives were to identify the best composite surface treatment to enhance SBS and determine which surface treatment produced the least surface damage at debond.

Methods

Forty dental composite samples were selected from four different manufacturers (n = 160) and grouped by manufacturer, one standard multi-shade dental system (FilTek™ Supreme Ultra) and three single-shade dental composites systems (OmniChroma®, SimpliShade™ and Venus® Diamond One). Each group of forty samples was randomly divided into four sub-groups (n = 10). Each sub-group was identified by the surface treatment used, hydrofluoric acid (HFA), micro-etching (MIC), or phosphoric acid (PA). Shear bond strength testing and adhesive remnant index (ARI) were performed. Statistical analyses included Kruskal-Wallis, Wilcoxon rank-sum, and two-factorial ANOVA.

Results

OmniChroma® had statistically significant lower shear bond strength than the other composite materials tested. The control groups had statistically significant lower shear bond strength than Group 1/HFA (P < 0.001) and Group 2/MIC (P < 0.001). Group 1/HFA had the lowest distribution ARI score overall, while MIC had the highest ARI score distributions.

Conclusions

The results of this in-vitro study found that all tested composite materials achieved clinically acceptable shear bond strengths. The utilization of micro-etching produced higher SBS. Significant Adhesive Remnant Index scores (< 0.001) were only found for OmniChroma® without any surface preparation.

正畸托槽与单色复合材料表面的剪切粘接强度：不同表面制备方法的体外比较研究。

目的：本研究的主要目的是确定哪种单色复合材料表面能产生临床上可接受的金属正畸托槽剪切粘结强度（SBS）。次要目标是找出提高 SBS 的最佳复合材料表面处理方法，并确定哪种表面处理方法在脱粘时产生的表面损伤最小：从四家不同的生产商（n=160）处选取了四十个牙科复合材料样品，并按生产商进行分组，包括一个标准多色牙科系统（FilTek™ Supreme Ultra）和三个单色牙科复合材料系统（OmniChroma®、SimpliShade™ 和 Venus® Diamond One）。每组 40 个样本被随机分为四个子组（n=10）。每个子组根据所使用的表面处理方法（氢氟酸 (HFA)、微蚀刻 (MIC) 或磷酸 (PA)）来确定。进行了剪切粘接强度测试和粘接残余指数（ARI）。统计分析包括 Kruskal-Wallis、Wilcoxon 秩和和双因子方差分析：结果：OmniChroma® 的剪切粘接强度明显低于其他受测复合材料。对照组的剪切粘接强度在统计学上明显低于第 1 组/HFA（PC 结论：体外研究结果表明，所有测试的复合材料都达到了临床可接受的剪切粘接强度。利用微蚀刻可产生更高的 SBS。显著的粘合剂残留物指数得分 (
