OBJECTIVE
To test the manufacturer's recommendation for the application rubbing time of a self-etching primer (Transbond Plus, 3M Unitek) and to compare the resulting bond strength of a resin composite (Transbond XT, 3M Unitek) in the traditional laboratory tension on all four wings with a simulation of the clinical single-wing lift-off debonding instrument (LODI; 3M Unitek).
MATERIALS AND METHODS
Flattened stainless-steel maxillary incisor orthodontic brackets (Victory Series, 3M Unitek) were bonded to 108 flattened bovine incisors. The enamel was rubbed with the self-etching primer for 0, 5 (the manufacturer's recommendation), and 10 seconds during a 10-second application. Traditional four-wing and LODI simulated debonding forces and the adhesive remnant index (ARI) were recorded.
RESULTS
One-way analysis of variance testing among rubbing times and debonding methods indicated a significant difference in strength with 0 and 5 seconds of rubbing and between traditional and LODI simulated tension. The bond strengths were higher in the ARI = 1 subset compared to the ARI = 3-5 subsets.
CONCLUSIONS
The manufacturer's recommendation for primer rubbing time produced the highest bond strength. Less force is required for debonding when tension is applied to one wing (LODI simulation) vs on all four wings.
目的
测试自酸蚀底漆（Transbond Plus，3M Unitek）的制造商推荐应用摩擦时间，并比较在传统实验室张力下所有四个翼上的树脂复合材料（Transbond XT，3M Unitek）的粘结强度与临床单翼分离器械（LODI；3M Unitek）的模拟结果。
材料与方法
将平坦的不锈钢上颌切牙正畸托槽（Victory Series，3M Unitek）粘结到 108 个平坦的牛切牙上。在 10 秒的应用过程中，用自酸蚀底漆摩擦 0、5（制造商推荐）和 10 秒。记录传统的四翼和 LODI 模拟分离力和粘结残留指数（ARI）。
结果
在摩擦时间和分离方法之间进行的单向方差分析表明，在 0 和 5 秒的摩擦以及传统和 LODI 模拟张力之间存在显著的强度差异。ARI=1 亚组的粘结强度高于 ARI=3-5 亚组。
结论
制造商推荐的底漆摩擦时间产生了最高的粘结强度。当在一个翼上（LODI 模拟）施加张力时，分离所需的力小于在所有四个翼上施加张力时的力。
