Abstract

Objective: The objective of this study was to evaluate the shear bond strength of metal brackets bonded with indirect bonding, under different surface treatment protocols.

Material and methods: 40 bovine teeth were randomly divided into four groups (n = 10), according to the type of surface treatment: G1 = 70% alcohol, G2 = air/water spray, G3 = 100-µm aluminum oxide blasting, G4 = direct boning. After drying, the standard Edgewise central incisor brackets were bonded with light-cured resin. The brackets were moved from the plaster models by means of a transfer tray made with condensation silicone, and bonded to the surface of the enamel with self-curing adhesive. The samples were submitted to shear tests by a universal test machine. Data were analyzed with SPSS 20.0 by the one-way ANOVA test and the Tukey post-test.

Results: No statistically significant difference (p=0.174) was observed between the mean forces measured between the group for shear strength values of the groups during the test: G1 (5.33 MPa), G2 (3.52 MPa) and G3 (4.58 MPa).

Conclusion: The bracket surface treatment protocols presented similarities in shear bond strength test. However, alcohol 70% and oxide blasting presented higher absolute values of resistance than the water group.

间接粘接中使用的托槽底座清洁方法是否会影响与牙釉质的粘接？

研究目的本研究旨在评估不同表面处理方案下间接粘接金属托槽的剪切粘接强度。材料和方法：根据表面处理类型将 40 颗牛牙随机分为四组（n = 10）：G1 = 70% 酒精，G2 = 空气/水喷雾，G3 = 100 微米氧化铝喷砂，G4 = 直接剔骨。干燥后，用光固化树脂粘结标准 Edgewise 中切牙托槽。用冷凝硅胶制作的转移托盘将托架从石膏模型上移开，并用自固化粘合剂粘合到珐琅表面。样品通过万能试验机进行剪切试验。数据用 SPSS 20.0 进行单因素方差分析和 Tukey 后检验：在测试过程中，各组的剪切强度值的平均测量力之间没有发现明显的统计学差异（P=0.174）：G1（5.33 兆帕）、G2（3.52 兆帕）和 G3（4.58 兆帕）：支架表面处理方案在剪切结合强度测试中表现出相似性。结论：支架表面处理方案在剪切粘接强度测试中表现相似，但 70% 酒精和氧化物喷射的绝对阻力值高于水组。
