The study evaluated the effect of different surface treatments on the surface roughness of a new-generation fiber-reinforced CAD-CAM composite resin (FRC) and its bond strength to veneered composite resin. Fifty specimens (10 mm × 10 mm × 1 mm) were prepared from FRC blocks (Trinia; Shofu) and embedded in acrylic resin. The specimens were divided into five groups (n = 10) for different surface treatments: nontreated (control), Al₂O₃ airborne particle abrasion, silica coating (Cojet), acid etching (H₂SO₄) and hydrogen peroxide (H₂O₂) application. Surface roughness (R_a) of the specimens was measured using a profilometer. A veneering composite resin (3 mm in diameter by 4 mm in length) was applied on the specimens. The shear bond strength between the FRC and the veneering resin was measured. A one-way analysis of variance was used to analyze the data. The differences among the groups were analyzed with Dunn post hoc tests (α = 0.05). Surface treatments increased the surface roughness, and Al₂O₃ airborne particle abrasion resulted in the highest R_a value followed by H₂SO₄, Cojet, H₂O₂ and control group (P < 0.05). The highest shear bond strength was achieved with Al₂O₃ application (P < 0.05). Cojet and H₂O₂ applications resulted in higher shear bond strength than the control (P < 0.05). H₂SO₄ application resulted in lower bond strength than the control (P < 0.05). Surface treatments increased the surface roughness of FRC. Al₂O₃ and silica coating increased the surface roughness more than the chemical applications. The tested surface treatments can be used to increase the bond strength except for the H₂SO₄ application. © 2021 Society of Chemical Industry

表面处理对种植体支持假体用CAD-CAM多向玻璃纤维增强复合树脂粗糙度和粘结强度的影响

该研究评估了不同表面处理对新一代纤维增强 CAD-CAM 复合树脂 (FRC) 的表面粗糙度及其与贴面复合树脂的粘合强度的影响。用 FRC 块（Trinia; Shofu）制备 50 个试样（10 mm × 10 mm × 1 mm）并嵌入丙烯酸树脂中。将样品分为五组（n = 10）进行不同的表面处理：未处理（对照）、Al ₂ O ₃空气传播颗粒磨损、二氧化硅涂层（Cojet）、酸蚀刻（H ₂ SO ₄）和过氧化氢（H ₂ O ₂ ) 应用。表面粗糙度 ( R _a) 的样品使用轮廓仪测量。将饰面复合树脂（直径为 3 毫米，长度为 4 毫米）涂在样品上。测量了 FRC 和饰面树脂之间的剪切粘合强度。使用单向方差分析来分析数据。使用 Dunn post hoc检验分析各组之间的差异（α = 0.05）。表面处理增加了表面粗糙度，Al ₂ O _{3 气}载颗粒磨损导致最高的R _a值，其次是H ₂ SO ₄、Cojet、H ₂ O ₂和对照组（P < 0.05)。Al ₂ O ₃应用达到最高剪切粘合强度（P < 0.05）。Cojet 和 H ₂ O ₂应用导致比对照更高的剪切粘合强度（P < 0.05）。H ₂ SO ₄应用导致粘合强度低于对照（P < 0.05）。表面处理增加了 FRC 的表面粗糙度。Al ₂ O ₃和二氧化硅涂层比化学应用增加了更多的表面粗糙度。除 H ₂ SO ₄外，经测试的表面处理可用于增加粘合强度应用。© 2021 化学工业协会
