- Primary Outcome Measures
Name Time Method The primary aim of this study is to analyze the bracket positioning accuracy of 3D printed transfer trays compared to directly bonded brackets in vivo.<br>For this purpose, the bracket offset of the bonded bracket position to the designed bracket position is analyzed in mm and degrees at T0 (directly after bonding the brackets), T1 (3 months after bonding) and T2 (6 months after bonding the brackets) by means of an intraoral scan. The measurement method used is a software-based iterative-closest-point (ICP) algorithm.<br>This end point is reached at these defined times (T0, T1, T2). <br>
- Secondary Outcome Measures
Name Time Method As a secondary objective, the impact of the bracket positioning accuracy in relation to the different tooth groups (incisors, canines, premolars, molars) of 3D printed transfer splints compared to directly bonded brackets is investigated.
