Digital vs. Conventional Indirect Bonding in Teens

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This randomized split-mouth trial compares digital indirect bonding with conventional indirect bonding for fixed orthodontic brackets in adolescents. Each participant receives both methods, with arch assignment determined randomly. The study measures how long bonding takes and tracks bracket failures during the first month after placement. Digital bonding uses a digital workflow to make transfer trays and pre-coated adhesive, while conventional bonding uses a standard lab workflow and standard adhesive. The goal is to see if the digital approach can match or improve efficiency and early bracket stability.
