    Effectiveness of Tooth Movement with Two Different Aligner Staging Protocols – a Randomised Controlled Multi-Centre Study


    In this randomised controlled, multi-centre study, the effectiveness of two differentiated aligner staging protocols (weekly versus biweekly) was investigated with regard to the effectiveness of the planned tooth movements and the change in the PAR score.

    Eighty-eight subjects were recruited in four centres (two university hospitals: Düsseldorf and Mainz and two specialist orthodontic practices: Cologne and Berlin) and randomly assigned to either Group A (two-week schedule) or group B (one-week schedule) with results stratified by initial status and sex. In total, 83 subjects (exclusion because of a screening error and five drop-outs) were analysed. All subjects received a set of ClearCorrect® aligners according to the assigned treatment plan. The number of aligners and the sequence of tooth movement were therefore individually adjusted and differed between the subjects.

    The data analysis of the six-month follow-up visits is presented here for the first time. The treatment performance of the aligners is analysed with the primary parameter PAR score and the secondary endpoint influence of the staging protocol on the effectiveness of various tooth movements.

    The aim of this study is to provide evidence-based findings on the optimal staging duration of aligner treatment. The results will help to improve the efficacy and safety of treatment with aligners and ultimately patient outcomes and satisfaction.
