The tendency of indicating early treatment (before growth spurt) when dealing with Angle Class II cases has been noticed, although there is no definite scientific evidence to justify such decision. The aim of this study was to identify the advantages and disadvantages to this approach and which appliances are used for this purpose. For that purpose, a questionnaire containing full records of a Class II patient was sent to two professors of each Orthodontic graduate program in Brazil (n=96, total 192), from which 107 were properly answered. Results demonstrated that the most used appliances were the headgear (80.4%), maxillary splint (50%) and Bionator (44.4%). The benefits most often quoted were increase of patient self-esteem (78.5%) and reduction in the incidence of incisors trauma (63.6%), while the main disadvantage was saturation of patient compliance (73.8%). Considering early Class II treatment, there is still no unanimity as to treating in one or two stages or in selection of appliances. However, the orthodontists should consider the physical situation of the patient, severity of cases and susceptibility of trauma to the maxillary incisors. It is crucial that updated information is given to parents, in order to justify this approach.
