Abstract:

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 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.
RESULTS AND CONCLUSION: The dropout rate of 3M TransbondTM 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.
