[Autotransplantation of a maxillary incisor and orthodontic care: a case study].

Introduction: Severely impacted teeth with atypical root anatomy do not respond well to orthodontic traction after surgical exposure. Consequently, they are often removed, but replacing them with dental prostheses can prove difficult in patients who are still growing. Thus, autotransplantation seems to be the only way to preserve a natural tooth and the alveolar bone.

[Methodology for clinical research in Orthodontics, the assets of the beOrtho website].

The rules applying to the "evidence-based" methodology strongly influenced the clinical research in orthodontics. However, the implementation of clinical studies requires rigour, important statistical and methodological knowledge, as well as a reliable environment in order to compile and store the data obtained from research. We developed the project "beOrtho.

Evidence-based orthodontics or the paradigm shift.

Practicing evidence-based orthodontics means offering patients treatment, which complies with scientifically-established data. However, how can we assess what science has determined to be certain given the confusing welter of information made available to us? The search for proof is a process, which requires knowledge of clinical methodology. It aims to set up a hierarchical classification of scientific and clinical studies and to assess their validity.
