Abstract

CONTEXT

Displacement of bracket after initial placement on tooth surface in the precure phase of bonding influences the shear bond strength.

AIMS

The aim of this study was to evaluate the influence of bracket displacement during the precure phase after initial placement on the tooth surface on shear bond strength of chemical cure and light cure composites.

SETTINGS AND DESIGN

experimental study.

SUBJECTS AND METHODS

Stainless steel orthodontic premolar brackets were bonded to the buccal surfaces of 88 maxillary 1 premolar teeth. Teeth were divided into four groups: (1) Group 1 - Control group for light-cure composites, (2) Group 2 - Displacement group for light-cure composites, (3) Group 3 - Control group for chemical cure composites, and (4) Group 4 -Displacement group for chemical cure composites. In the control groups, the brackets were bonded with no precure bracket displacement. In the displacement groups, the brackets were bonded with 2 mm precure linear displacement. Photoactivation was carried out for light-cure composites. Shear bond strength tests were carried out using the universal testing machine. Statistical analysis used: Data were analyzed using the one-way analysis of variance test.

RESULTS

The mean shear bond strength of Groups 1, 2, 3, and 4 were observed to be 14.49 ± 0.75, 13.40 ± 0.61, 12.34 ± 0.53, and 11.55 ± 2.43MPa, respectively, with the displacement groups showing lower shear bond strength when compared to the control groups. Whether displaced or not, chemically cured composites showed lower bond strength when compared to light-cured composites.

CONCLUSIONS

Displacement of brackets during bracket placement seemed to reduce the enamel bond strength after the final positioning of the bracket.

摘要

背景

在粘结的预固化阶段，托槽在牙齿表面初始放置后发生移位会影响剪切粘结强度。

目的

本研究的目的是评估在牙齿表面初始放置后，预固化阶段托槽移位对化学固化和光固化复合材料剪切粘结强度的影响。

设置与设计

实验研究。

对象与方法

将不锈钢正畸前磨牙托槽粘结到88颗上颌第一前磨牙的颊面。牙齿分为四组：（1）第1组 - 光固化复合材料对照组，（2）第2组 - 光固化复合材料移位组，（3）第3组 - 化学固化复合材料对照组，（4）第4组 - 化学固化复合材料移位组。在对照组中，托槽粘结时无预固化托槽移位。在移位组中，托槽粘结时有2mm的预固化线性移位。对光固化复合材料进行光活化。使用万能试验机进行剪切粘结强度测试。统计分析方法：数据采用单因素方差分析进行分析。

结果

观察到第1、2、3和4组的平均剪切粘结强度分别为14.49±0.75、13.40±0.61、12.34±0.53和11.55±2.43MPa，与对照组相比，移位组的剪切粘结强度较低。无论是否移位，化学固化复合材料的粘结强度均低于光固化复合材料。

结论

托槽放置过程中的移位似乎会降低托槽最终定位后与牙釉质的粘结强度。
