This study aims at presenting a complete workflow proposition for obtaining virtual orthodontic models, planning and virtual orthodontic setup, 3D printing, aligners preparation and use in routine orthodontic practice. For the study and determination of methods, a patient with anterior crossbite in mixed dentition was selected and subject to molding of dental casts. The latter were scanned by XCAD scanner. The .STL files were imported by Maestro 3D software in which the orthodontic setup was designed. Subsequently, STL files were exported and printed by Cube 3D printer. The prototypes served as models for manufacturing of orthodontic aligners which were installed in according to patient’s clinical evolution. Within 16 weeks of therapy with orthodontic aligners, patient’s malocclusion was corrected. Therapy with orthodontic aligners in mixed dentition is a feasible therapeutic possibility, combining patient’s comfort, clinical effectiveness and predictability of orthodontic movements according to the virtual planning.
