Abstract

Objectives: To test the hypothesis that there is no significant difference in clinical bracket failure between the 3M APC Mini Twin™ bracket system and the Transbond XT™ adhesive during orthodontic treatment. Design: A randomized, split mouth, prospective clinical trial. Setting and Sample Population: The Department of Orthodontics and Dentofacial Orthopedics at University of Missouri, Kansas City. Twenty-nine subjects who were treatment planned to receive comprehensive orthodontics using 0.018 slot appliances. Experimental Variable: The adhesive pre-coated brackets (APC) system was randomly assigned to one side of the mouth and the Transbond XT™ was assigned to the opposite side. Outcome Measure: The absence of any of the brackets at the time of a regular or emergency orthodontic appointment. Results: There was no significant difference (P > 0.05) in bracket failure between the 3M APC Mini TwinTM bracket system and the Transbond XT™ adhesive at any time period (90, 180, or 365 days). The failure rate of brackets on premolars was higher than on incisors or canines. Conclusion: APC Mini Twin™ bracket system and Transbond XT™ adhesive are equally effective in maintaining brackets clinically. Inexperienced operators had an overall 7.5% bond failure 12 months following bracket placement.
