摘要
目的：比较用于间接复合材料修复的高填充可流动复合材料（HFFC）和粘贴型复合材料的剪切-粘结-强度（SBS），并评估不同表面处理（ST）对复合材料修复方案的影响：使用 Gradia Plus 和 SR Nexco 间接复合材料制备了 84 个 5 × 5 × 2 毫米的圆柱形试样。样品经过 5000 次热循环处理。根据 ST 将样品分为三组（对照组、毛刺组和气磨组）。ST 后，根据修复材料的不同，样品分组又分为两组：粘贴型复合材料和 HFFC（n = 7）。再进行 5000 次老化循环。SBS 值用万能试验机（日本岛津）测量。采用 Shapiro-Wilk、3 方方差分析和 Tukey HSD 检验来评估数据（P < 0.05）：ST 被认为对 SBS 有显著影响（P <0.001）。对照组、锉刀和磷酸组、气磨组的平均值分别为（13.9 ± 5.7）、（17.0 ± 6.4）、（20.4 ± 4.9）MPa。对于 SBS 而言，表面处理与修复材料的交互作用被认为是显著的（P = 0.044）。在 SR Nexco、气磨 ST 和 HFFC 修复的相互作用下，观察到最高的平均粘接强度（24.5 ± 4.5 MPa）：结论：在气磨后使用 HFFC 进行修复可提高间接复合材料修复体的 SBS。
Assessment of a highly-filled flowable composite for the repair of indirect composites
Purpose: To compare the shear-bond-strength (SBS) of a highly-filled-flowable composite (HFFC) and a paste-type composite for indirect composite repair and to evaluate the effect of different surface treatments (ST), concerning the composite repair protocol.
Methods: Eighty-four 5 × 5 × 2 mm cylindrical specimens were prepared using Gradia Plus and SR Nexco indirect composite materials. The samples were thermocycled 5,000 times. According to the ST, the samples were divided into three groups (control, bur, and air-abrasion). After ST, the sample subgroups were divided into two sub-groups according to the repair material: paste-type composite and HFFC (n = 7). Another 5,000 cycles of aging were performed. SBS values were measured with a universal testing machine (Shimadzu, Japan). Shapiro-Wilk, 3-way ANOVA, and Tukey HSD test were used to evaluate data (P < 0.05).
Results: ST was considered significant for SBS (P < 0.001). The mean values were (13.9 ± 5.7), (17.0 ± 6.4), (20.4 ± 4.9) MPa for the control, bur and phosphoric acid, and air-abrasion groups, respectively. The surface treatment and repair material interaction was considered significant for SBS (P = 0.044). The highest mean bond strength (24.5 ± 4.5 MPa) was observed for the interaction of SR Nexco, air-abrasion ST, and HFFC repair.
Conclusion: Repairing with HFFC following air abrasion might enhance the SBS for indirect composite restorations.
