Does low-frequency vibration have an effect on aligner treatment? A single-centre, randomized controlled trial

ConclusionsConsidering all tooth and movement types of the 45 participants, the mean total imprecision was 2.1 ± 0.9 degrees, with respect to a mean prescription of 5.7 ± 2.2 degrees. There was no difference in accuracy between replacing the aligners accompanied by low-frequency vibration every 7 days and replacing them every 14 days without vibration. Moreover, low-frequency vibration seemed to improve th e accuracy of a conventional protocol in terms of upper incisor rotation.Trial registrationThe German Clinical Trials Register (DRK00015613).
