Behavioral therapy (or myofunctional re-education) acts on the central nervous system and not directly on facial tissues like other orthodontic treatment. This therapy was developed in two stages: first, orthodontists identified the role played by muscular pressure on the shape of dental arches (Blandin4, 1836), then by the elaboration of remedial treatment of malfunctions as well as the elimination of parafunctions (Johnston20, 1938). The School of Stomatology introduced these treatment methods in France in 1950.
