Abstract
Objective:
Verification of the therapeutic accuracy of the Incognito ® bracket system.
Material and 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.
Conclusion:
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.
Zusammenfassung
Ziel:
Verifizierung der Behandlungsgenauigkeit des Incognito®- Bracketsystems.
Material und Methodik:
Die therapeutischen Set-up- und Abschlussmodelle wurden mittels 3D-Scanner digitalisiert, virtuell überlagert und von jedem einzelnen Zahn die Abweichungen der Rotationen und Translationen in den drei Raumdimensionen berechnet.
Ergebnisse:
Die Frontzähne zeigten Abweichungen der Rotationen von weniger als 4,6° und der Translationen von unter 0,5 mm. Außerdem wurden besondere Einflüsse wie Kiefer, Wachstum, Zahn-Typ, Frontzahnstellung, Bracketgeneration, Hardware des 3D-Scanners und verwendete Finishing-Bögen analysiert.
Schlussfolgerung:
Der klinisch gewonnene Eindruck konnte durch die Messergebnisse der Studie bestätigt werden. Eine zufriedenstellende Übereinstimmung des Endergebnisses mit dem therapeutischen Set-up ist in der Lingualtechnik mittels individualisierter Brackets realisierbar.
