“…In addition, the population of subjects without change, studied for the reference values of IOPI, is of American nationality 16 , which could have differed from subjects of this research due to ethnic differences. Some studies 26,27 already noted the influence of ethnicity on the dimensions and proportions of teeth.…”

Objective: to evaluate the resistance and pressure of the lips in Class I, II and III Angle’s malocclusion subjects, in comparison to reference values and relate them with gender and age. Methods: a quantitative, descriptive and cross-sectional study. Participants included 40 subjects, 20 women and 20 men, average age 26.3 years, separated by occlusal classification. The volunteers answered on the self-reported performance of the stomatognathic functions and were submitted to the evaluation of the mobility and posture of the lips. Pressure and resistance were measured with the Iowa Oral Performance Instrument (IOPI) and the results compared to the reference values described in the instrument´s manual. The data were analyzed descriptively and, for inferential analysis, Pearson's Chi-Square test was used. The significance level was considered 5%. Results: a decrease in pressure and resistance values wasobserved in all patients, including Angle’s class I group. There was an inverse relationship between the age of the subjects and the values of pressure of lips with statistical significance (p = 0.02). In general, women had lower pressure values than men. Conclusion: all study subjects had lower pressure of the lips than the reference values described in the literature.

“…O diagnóstico da Classe III esquelética precisa de uma avaliação minuciosa de várias características; facial, oclusal, radiográfica/cefalométrica. Levando sempre em consideração a população que o paciente pertence, o local que está inserido e informações genéticas (Ferreira et al, 2014). Fatores locais, como problemas de postura mandibular, perda prematura de primeiros molares, distúrbios na erupção dos incisivos e hipertrofia de adenóides e tonsilas, são considerados etiológicos para essa má oclusão.…”

A má oclusão de Classe III é caracterizada pelo relacionamento anteroposterior anormal entre a maxila e mandíbula, onde, em muitos casos, ocorre uma relação de mordida cruzada anterior. Ela pode ser interceptada durante a fase de crescimento e desenvolvimento craniofacial mediante o uso de aparelhos ortopédicos. Assim, o tratamento precoce permite redirecionar o crescimento de forma mais favorável. Este trabalho teve como objetivo descrever o tratamento e mostrar os resultados da terapia em um paciente na fase de dentadura mista com má-oclusão de Classe III de Angle. Paciente do sexo feminino, 9 anos de idade, leocoderma, procurou por tratamento ortodôntico no Curso de Especialização em Ortodontia da Unidade Avançada de Pós-Graduação FACOP – Manaus/AM, promovido pelo Instituto Brasileiro de Ensino do Norte – IBEN, com a queixa principal de “mordida errada”. Portadora de má oclusão de Classe III de Angle e mordida cruzada anterior, o plano proposto foi tratamento ortopédico de tração reversa da maxila com disjuntor de Mcnamara e máscara facial de Petit. Após o uso correto e disciplinado destes aparelhos pela paciente, foi conseguido a correção da má oclusão de Classe III, o descruzamento da mordida anterior, melhora na relação maxilo-mandibular e um sorriso mais harmonioso. Posteriormente foi introduzido o uso do aparelho fixo para o devido alinhamento/nivelamento dos elementos dentários.

Objective: to correlate the nasolabial angles (ANL) and mentholabial groove (ASML) with the straight, concave and convex facial profiles, determined through subjective analysis, for application in orthodontic facial analysis. Method: a cross-sectional, retrospective and analytical study was carried out, with a sample of 184 documents from patients aged between 21 and 36 years old, being 107 woman and 77 man; belonging to the collection of the Specialization Course in Orthodontics, UNIFIP / PB, Brazil. The profile photographs were analyzed, through the subjective method, by visual analysis, under inter-examiner calibration, for classification of the profiles in: straight, concave and convex. For this, the projections of the upper and lower lips were considered, as well as their relationship with the projection of the chin and nose. In lateral radiographs, ANL and ASML angles were drawn for cephalometric analysis. The angles were transcribed through the construction of the facial profile of soft tissues from teleradiographies, in a negatoscope, outlined with ultrafan paper, through the contour of the anatomical soft tissue profile. The data were tabulated on a specific form for this purpose. Results: the majority of the sample consisted of women (58.2%); by brown patients (63.6%); convex profiles (50.0%); and with woman ANL angles 103.53º (± 9.78) and man 103.27º (± 11.65); and ASML, within the normal range 132, 07º (± 9.54º) for both sexes, respectively. There was no significant correlation between facial profiles and ANL and ASML angles. Conclusion: the ANL and ASML angles did not influence the facial profiles for the studied sample.
