“…The assorted commercial software systems are multifunctional and generally integrate three-dimensional digital models, setup and virtual bonding procedures, and prototyped transfer trays. However, Oliveira and Pretti (2018) state that, in computer-aided bonding, results diverge and seem to depend especially on the type of software system applied. Although virtual indirect bonding has been considered more accurate when compared to direct bonding (Oliveira et al 2019), according to Israel et al (2011), virtual bracket placement methods do not establish more precise positioning in comparison to traditional indirect bonding techniques.…”

Despite being associated with more accuracy, the indirect bonding procedure is not yet the gold standard, probably because of sensitivity of the numerous variables that must be controlled. The aim of this article was to present a modified, standardized, and low-cost indirect bonding technique that allows this procedure to be performed successfully. The technique covers an initial clinical stage, to obtain the models; a laboratory stage, which involves placement of brackets on the models following the facial axis of the clinical crown and the labial projection of the marginal ridges of the posterior teeth and construction of transfer tray using hot glue; and a second clinical stage, to properly transfer the brackets to patient’s teeth. Hot glue used to build the tray molds the teeth and perfectly adapts to the teeth, having enough stiffness to maintain their anatomy and the position of the brackets, but also presenting adequate flexibility to allow removal of the tray avoiding excessive stress over the brackets. In conclusion, the new simplified indirect bonding technique presented here provides a precise placement of brackets on the models, a cheaper way to transfer them to patient, and an easy removal of transfer tray, being a very simple and cost-effective method.
