Therapeutic accuracy of individualized brackets in lingual orthodontics.
OBJECTIVE
Verification of the therapeutic accuracy of the Incognito ® bracket system.


METHODS
The therapeutic set-up casts and final treatment casts were digitalized using a 3D scanner, and the scans were subsequently superimposed. The deviations in rotation and translation of each tooth in the three spatial dimensions were calculated.


RESULTS
The front teeth showed deviations in rotations of less than 4.6 ° and in translations under 0.5 mm. In addition, influences such as upper or lower jaw, growth, type of tooth, anterior tooth position, bracket generation, 3D scanner hardware and finishing archwires were analyzed.


CONCLUSIONS
The clinical impression was confirmed by the measurements taken in this study. The final results following lingual orthodontic treatment using individualized brackets correlate satisfactorily with the therapeutic set-ups.
