Abstract
The accuracy of orthodontic appliances made with 3D printing, such as aligners, bonding trays and surgical splints, compared to traditional methods is of interest. Fifteen studies were analyzed, focusing on fit, dimensional deviations and accuracy. Results showed 3D-printed aligners offer better accuracy and resistance than conventional ones. The fit of 3D-printed indirect bonding trays and retainers was clinically acceptable, with gypsum casts showing less volumetric change. 3D-printed NAM aligners improved accuracy, comfort and nasal symmetry. Thus, 3D printing offers better precision, accessibility and patient care in orthodontics.
