Abstract:
Orthodontics in Brazil underwent significant transformations in the 1950s when several dentists returned to the country after completing advanced education courses in the specialty abroad. The first two orthodontic associations, in Rio de Janeiro and São Paulo, were constituted in 1955 and 1959. The specialty's first event with characteristics of a professional meeting occurred in São Paulo in 1957, and Postgraduate Orthodontic education became available. This paper aims to describe the central insights of the constitution and evolving of the education of Orthodontics in Brazil.
