Declarations
:
: I. Graf, N.C. Bock, T. Bartzela, V. Röper, U. Schumann, K. Reck, H.-J. Helms, K. Höfer, U. Fritz, M. Wolf, D. Wiechmann, P.-G. Jost-Brinkmann, S. Ruf and B. Braumann declare that there is no conflict of interest regarding this research. One of the authors, D. Wiechmann, founded the company that fabricated the lingual brackets mainly used within the L‑MBA subgroup in this study. Yet, D. Wiechmann and I. Graf—as well as all other authors—declare that this had no influence on the present study, its data analyses and research outcome.
: All corresponding ethics committees, the leading one being at the University Hospital of Cologne (#14-425), approved this multicenter cohort study. Signed informed consent from patients and/or their legal guardians was mandatory. All patient-related data were pseudonymized. The detailed recruitment procedure used at all study centers had been discussed with the Clinical Trials Center of the University Hospital of Cologne before the study started.
