Summary

Accurate bracket positioning is crucial for effective fixed orthodontic treatment and a core component of orthodontic specialist training. Clinically, two main bonding techniques exist: direct and indirect. Due to limited high-quality trials, there is no conclusive evidence favoring direct or traditional indirect bonding for accuracy. Advances in digital dentistry have further optimized indirect bonding; 3D software allows orthodontists to position virtual brackets for digital tooth alignment, and CAD/CAM technology enables the production of digitally assisted transfer trays. This project will conduct a prospective randomized controlled trial to compare the effectiveness of different bonding methods including traditional direct bonding, traditional indirect bonding, indirect bonding using 3D-printed transfer tray, and indirect bonding using vacuum-formed transfer tray made with 3D-printed models. Outcomes will include bracket placement accuracy, chairside time, bonding failure rate, treatment adjustments, and cast-radiograph evaluation. Despite current costs of CAD/CAM in orthodontics, this study aims to train orthodontic residents, optimize patient care, and foster collaboration across orthodontic specialists and industry. The alternative hypotheses are: (1) Significant differences exist in bracket positioning accuracy across bonding techniques; (2) Bonding techniques vary significantly in chairside time, bonding failure rates, incidence of bracket repositioning, and additional tooth adjustments.
