背景：目前正畸后牙多以黏结颊面管来替代黏结带环来控制牙齿位置和方向，但磨牙位置靠后，磨牙颊面管的黏结相对困难；同时，后牙咀嚼受力相对较大，造成颊面管更易脱落。目的：探讨两种不同正畸黏结剂黏结牙颊面管的效果。方法：随机选择60例正畸治疗患者，每例患者右侧上下第一磨牙均采用3M TransbondTM光固化树脂黏结剂黏结，左侧上下第一磨牙均采用3M Unitek化学固化黏结剂黏结。详细记录4个月内颊面管黏结后的脱落情况。同时分别以3M TransbondTM结果与结论：3M Transbond光固化树脂黏结剂、3M Unitek化学固化黏结剂黏结人离体第一磨牙，模仿口腔正常环境和温度，冷热循环10000次后测定黏结抗剪切强度。TM光固化树脂黏结剂组和3M Unitek化学固化黏结剂组的脱落率分别为10.80%和24.10%，两组间比较差异有显著性意义(P <0.05)。体外实验结果进一步证实两种黏结剂均能满足临床要求，但3M TransbondTM光固化树脂黏结剂黏结强度高于3M化学固化黏结剂。提示3M TransbondTM光固化树脂黏结剂较3M化学固化黏结剂更适合磨牙颊面管的黏结。

BACKGROUND:Currently, buccal tubes are mostly preferred rather than molar bands to control posterior tooth movement. However, the buccal tube is difficult to bind the molar because of its position. Meanwhile, due to the relatively large masticatory forces on the posterior tooth, the buccal tube is easier to drop off. OBJECTIVE: To investigate the clinical effects of two kinds of adhesives bonding the buccal tube. METHODS:Sixty orthodontic patients were selected randomly. The right side of the upper and lower first molars of each patient was bonded by 3M TransbondTM light-cured resin binder, and the left side of the upper and lower first molar of each patient was bonded by 3M chemical curing adhesive. Cases of buccal tube shedding were recorded within 4 months. Meanwhile, 3M TransbondTM RESULTS AND CONCLUSION: The dropout rate of 3M Transbond light-cured resin binder and 3M chemical curing adhesive were used to bond the isolated human first molar, respectively. The normal oral environment and temperature were stimulated, and the shear bonding strength was measured after measured after 10 000 thermal cycles. TM light-cured resin binder and 3M chemical curing adhesive groups was 10.80% and 24.10% respectively, and there was a significant difference (P < 0.05). In vitro experiments confirmed that two kinds of adhesives could meet the clinical requirements, but 3M TransbondTM light-cured resin binder was better than 3M chemical curing adhesive. These findings indicate that compared with 3M chemical curing adhesive, 3M TransbondTM light-cured resin binder is more suitable for the binding between the molar and buccal tubes.
