“…Nanda et al 24 observed in a longitudinal study of untreated patients, ages between 7 to 18 years, that the mandibular plane, occlusal plane, palatal plane and the gonial angle decrease with age. The same was reported by Haralabakis and Sifakakis, 15 in which agreed that the treatment and especially the growth seem to favor the dolichofaciais. According to the authors, these progressive reductions of the angles improve or maintain the magnitude of vertical imbalance.…”

“…15 all patients who had in their medical records the angle FMA greater than 28°, because, according to Tweed, 30 they have an unfavorable growth vector, i.e. greater vertical growth propensity.…”

“…As a result, numerous authors [2,22,40,44,55] have spoken out against the use of cervical headgears in the presence of vertical growth or open-bite situations. This thinking draws heavily on data obtained with combined headgear and multiband treatment [3,8,11,12,18,23,24,29,36,43,45]. Authors dealing exclusively with the effects of headgear treatment have either confined their discussion to individual case reports [16,31,33,34,39] or excluded patients with vertical growth patterns in the first place [1,14,26].…”

“…Similarly, Jonas [21] did not find that downward backward rotation of the mandible was typical of headgear treatment. Haralabakis & Sifakakis [18] and Hubbard et al [19] grouped their patients into "high-angle" versus "lowangle" cases but failed to establish any differences in growth pattern changes. Nor did Baumrind et al [5] find that highangle cases generally differed.…”

“…Assumindo uma excelente colaboração do paciente, o aparelho extra-oral de tração cervical, ou também chamado tipo Kloehn, é um aparelho simples e de alta efetividade para a correção da maloclusão Classe II 2 . O aparelho extra-oral de tração cervical é indicado para casos de pacientes com protrusão maxilar e dimensão vertical reduzido 8 e pode ser utilizado como auxiliar na ancoragem 2,5 . Os efeitos geralmente produzidos por esse tipo de aparelho são: distalização 2 e extrusão dos molares superiores 1,4,6,8 , deslocamento posterior 1,8 ou restrição do crescimento da maxila 1,5 , aumento da dimensão vertical, rotação da mandíbula no sentido horário 8,4,6,3 e inclinação anterior do plano palatal 1,8 .…”
