摘要
评估纳米陶瓷混合 CAD/CAM 块体与两种大量填充复合材料在不同表面预处理后的深边缘隆起剪切粘接强度（SBS）。从每组团状填充树脂复合材料（BRC）（SonicFill 3/SF、VisCalor bulk/VS）中制备 40 个圆柱形样品（直径 3 毫米×高 4 毫米），从 Grandio Block 中切分 80 个样品（14.5 毫米×7.2 毫米×2 毫米）。每个 BRC 样品被分成两组，其中一组的表面经过摩擦化学二氧化硅涂层处理。CAD/CAM 块样本表面用氧化铝颗粒处理。使用双固化通用树脂基水泥（Bifix QM）对 CAD/CAM 块和复合材料样品进行砌筑。在蒸馏水中浸泡 24 小时后，样品被分为直接组和测试组。测试组进行热循环（5-55 °C，10,000 次循环）。砌块和 BRC 之间树脂基水泥的 SBS 在通用测试装置上进行测试，直至失效。使用体视显微镜确定失效类型。用扫描电子显微镜对粗糙模式进行评估。统计分析包括 Shapiro Wilk 检验、广义线性模型检验和费雪精确检验（0.05）。老化过程导致平均 SBS 值之间存在显著的统计学差异 ( < 0.001)。即时组的平均 SBS 值为 33.7 ± 7.9 兆帕，而热循环后测试组的平均 SBS 值为 22.6 ± 6.3 兆帕。就 SBS 值而言，两种填充树脂复合材料的表现相似。虽然摩擦化学二氧化硅涂层获得了更高的 SBS 值，但热循环对粘合的不利影响无法避免。
Evaluation of the shear bond strength between CAD/CAM blocks and sonic/thermoviscous bulk-fill composites with different surface treatments
Background/purpose
To evaluate the shear bond strength (SBS) of nanoceramic hybrid CAD/CAM blocks with two bulk-fill composites in deep margin elevation following different surface pretreatments.
Materials and methods
Forty cylindrical-shaped samples (3 mm diameter × 4 mm height) were prepared from each group of bulk-fill resin composites (BRC) (SonicFill 3/SF, VisCalor bulk/VS), and 80 samples (14.5 mm × 7.2 mm × 2 mm) were sectioned from Grandio Block. Specimens of each BRC were assigned to two subgroups, and surfaces of one group were treated with a tribochemical silica-coating. The CAD/CAM block sample surfaces were treated with Al2O3 particles. CAD/CAM block and composite samples were luted using dual-cure universal resin-based cement (Bifix QM). Following immersion in distilled water for 24 h, the samples were divided as immediate and test groups. The test group was subjected to thermocycle (5–55 °C, 10,000 cycles). The SBS of the resin-based cement between the blocks and BRC was tested on a universal testing device until failure. Failure type was determined using a stereomicroscope. The roughening pattern was evaluated with SEM. Statistical analysis included Shapiro Wilk, Generalized Linear Models, and Fisher's Exact tests (P < 0.05).
Results
No statistically significant difference was found between the mean SBS values according to deep margin elevation materials and surface pretreatment (P > 0.05). Aging procedure resulted in a statistically significant difference between the mean SBS values (P < 0.001). While the mean SBS value was 33.7 ± 7.9 MPa in immediate group, it was calculated as 22.6 ± 6.3 MPa in test group following thermocycle.
Conclusion
In terms of SBS, both bulk-fill resin composites performed similarly. Although higher SBS values were obtained with tribochemical silica-coating, the adverse effects of thermocycling on bonding could not be prevented.
