Data obtained from previous published papers, and also from questionnaires answered by 54 patients, showed that adult patients stood out for their attention to details and high interest in the esthetic improvements provided by treatment, and also for a greater perception of their initial malocclusion. On the other hand, the same data showed that adult patients, once informed about the limitations of their treatment and having confidence on the orthodontist, presented a high level of satisfaction with treatment results, revealing themselves as good patients for indication and execution of orthodontic procedures.

PR showed more frequency of ARR in posterior teeth groups when compared with CBCT images. ARR did not change in long-term post treatment.

OBJECTIVE: The aim of this study is to assess dentoskeletal symmetry in cone-beam computed tomography (CBCT) scans of Brazilian individuals with Angle Class I malocclusion. MATERIAL: A total of 47 patients (22 females and 25 males) aged between 11 and 16 years old (14 years) seen in a private radiology service (CIRO, Goiânia, GO, Brazil) were assessed. All CBCT scans were obtained from January, 2009 to December, 2010. Cephalometric measurements were taken by multiplanar reconstruction (axial, coronal and sagittal) using Vista Dent3DPro 2.0 (Dentsply GAC, New York, USA). Minimum, maximum, mean and standard deviation values were arranged in tables, and Student t-test was used to determine statistical significance (P < 0.05). RESULTS: Data were homogeneous, and differences between the right and left sides were not significant. CONCLUSIONS: Cephalometric measurements of Brazilian individuals with Angle Class I malocclusion can be used to establish facial symmetry and three-dimensional standard references which might be useful for orthodontic and surgical planning.

A má oclusão Classe II de Angle é caracterizada por uma discrepância dentária ântero-posterior, que pode ou não estar associada a alterações esqueléticas. Além do comprometimento estético, o fato de vir associada a um overjet acentuado faz com que o paciente fique mais exposto a traumas dentários. Este caso foi apresentado à Diretoria do Board Brasileiro de Ortodontia e Ortopedia Facial (BBO), representando a categoria 4, ou seja, uma má oclusão com discrepância ântero-posterior acentuada, Classe II com ANB maior ou igual a 5º, como parte dos requisitos para a obtenção do título de Diplomado pelo BBO. Possui uma característica incomum, que é a ausência congênita de um incisivo inferior.
