Abstract
Introduction: Orthodontics have been affected by digital technology, including diagnostic tools, treatment planning, appliance production, and 3D printing. To enable bracket arrangement more precisely and effectively, various CAD applications were available. Numerous research that examined the effectiveness and precision of the digital indirect bonding approach discovered that it is, overall, an effective solution. However, there was little investigation on the literatures regarding the external reliability of digital indirect bonding systems. Aim of the study: to assess digitally the amount of variation in bracket locations that occurred during their transfer using an indirect bonding tray within the patient's mouth, as well as the exterior accuracy of the measurements. Discussion: The present study's overall angular differences varied from 0.51° to 1.94° and its overall linear differences ranged from 0.1731 mm to 0.2002 mm; these values coincided with those found in the literature, demonstrating the technique's dependability. Conclusion: The position of brackets on digital models can be accurately replicated by indirect bonding using a dual transfer tray.
