Abstract in Portuguese
Este estudo retrospectivo teve como objetivo comparar os efeitos esqueléticos, dentários e tegumentares do tratamento com Aparelho de Protração Mandibular (APM) em conjunto com o aparelho fixo em pacientes adolescentes e adultos com má oclusão de Classe II. A amostra foi composta por telerradiografias pré e póstratamento de 23 adolescentes (idade inicial média de 11,75 anos) e de 16 adultos (idade inicial média de 22,41 anos). Testes t (P < 0,05) foram empregados para comparação dos grupos. Os adultos apresentaram menor quantidade de alterações esqueléticas. Com relação às alterações dentárias, os adultos apresentaram menor inclinação lingual dos incisivos superiores; menor extrusão dos incisivos inferiores; menor extrusão dos molares superiores e inferiores; menor mesialização dos molares inferiores; e menor retrusão do lábio superior em comparação aos adolescentes.

Abstract in English
The aim of this retrospective study was to compare the skeletal, dental, and soft tissue effects of the Mandibular Protraction Appliance (MPA) treatment in adolescent and adult Class II malocclusion patients. The sample comprised pretreatment and posttreatment cephalograms of 23 adolescents (mean pretreatment age 11.75 years) and 16 adults (mean pretreatment age 22.41 years). The groups were compared with t tests, at P < 0.05. The amount of skeletal changes was smaller in the adult group. Adults showed smaller maxillary incisors lingual tipping, mandibular incisor and molar and maxillary molar extrusion and mandibular molar mesialization. Additionally, adults also showed greater upper lip retrusion as compared to adolescents.
