Digital vs. Conventional Indirect Bonding.
Comparison of Indirect Bonding of Orthodontic Brackets Using Digital Versus Conventional Technology: A Randomized Controlled Trial on Bonding Time and Bracket Failure
This randomized split-mouth clinical trial will compare digital and conventional indirect bonding techniques for fixed orthodontic bracket placement in adolescent patients requiring treatment in both dental arches.
Each participant will receive both bonding techniques, with allocation of the digital and conventional indirect bonding procedures to the upper or lower arch determined by randomization. The study will evaluate the time required to complete bracket bonding procedures and the early clinical performance of the two techniques, assessed by bracket failure within the first month after appliance placement.

Descripción detallada
Indirect bonding has been proposed as an alternative to direct bonding for the placement of orthodontic brackets, with potential advantages in terms of clinical efficiency, bracket positioning, and patient comfort. In recent years, computer-aided three-dimensional design and manufacturing methods have enabled the production of digital transfer trays for indirect bonding, offering a potentially more standardized workflow compared with conventional laboratory-based procedures.
This randomized split-mouth clinical trial will compare digital and conventional indirect bonding techniques in patients undergoing fixed orthodontic treatment in both the upper and lower arches. Each participant will receive both techniques, with the allocation of the digital and conventional bonding procedures to the upper or lower arch determined by randomization.
In the digital indirect bonding procedure, transfer trays will be produced using a digital workflow and brackets will be bonded using a pre-coated adhesive system. In the conventional indirect bonding procedure, transfer trays will be produced using a standard laboratory workflow and brackets will be bonded using a conventional orthodontic adhesive system.
The study will assess the procedural efficiency of the two techniques by recording the time required to complete the bracket bonding procedure. Early clinical performance will be evaluated by recording bracket failures during the first month of orthodontic treatment. All procedures and follow-up assessments will be performed in a clinical orthodontic setting.
