Resumo: | Purpose: To compare the changes in the maxillary and mandibular dental arch forms and in incisors position in orthodontic cases treated with Damon and conventional appliances, with and without rapid maxillary expansion (RME). Methods: Sample comprised 75 Class I malocclusion patients with mild to moderate crowding treated orthodontically without extractions. The sample was divided into 3 groups: Group 1: 23 patients (mean initial age: 14.65 years) treated with Damon System for a mean period of 2.72 years; Group 2: 24 patients (mean initial age: 13.85 years) treated with RME followed by conventional fixed appliances for a mean period of 2.17 years; Group 3: 28 patients (mean initial age: 13.94 years) treated with conventional fixed appliances for a mean period of 2.20 years. Pretreatment and posttreatment dental casts and cephalograms of each patient were evaluated. Intergroup comparison of the variables was performed by ANOVA and Tukey test. Results: The maxillary intercanine, inter-second-premolar and intermolar widths showed a greater increase in Damon and RME groups. In the mandibular arch, the arch widths showed a greater increase in Damon group compared to the other two groups. There was greater protrusion of the maxillary incisors in Damon group than in the other 2 groups. For the mandibular incisors, Damon caused a greater protrusion and proclination when compared to the conventional appliance. Conclusions: The maxillary arch form showed similar increases in most of the distances to treatment with Damon and RME plus conventional appliances. The mandibular arch showed a greater increase in most of the measured distances in cases treated with Damon, compared to the conventional appliances with and without RME. Damon caused greater protrusion of the maxillary incisors. In the mandibular incisors, Damon caused a greater protrusion and proclination when compared to conventional appliance only. |

Metodologia: A amostra foi composta por 75 pacientes com má oclusão de Classe I, apinhamento suave a moderado, tratados ortodonticamente sem extrações. Grupo 1: 23 pacientes com idade média inicial de 14,65 anos, tratados com aparelhos autoligáveis do Sistema Damon, por um perído médio de 2,72 anos; Grupo 2: 24 pacientes com idade média inicial de 13,85 anos, tratados com ERM seguido por aparelhos fixos convencionais, por um período médio de 2,17 anos; Grupo 3: 28 pacientes com idade média inicial de 13,94 anos, tratados com aparelhos convencionais, por um perído médio de 2,20 anos.Os modelos de gesso e as telerradiografias foram avaliados ao início e ao final do tratamento. A comparação intergrupos das variáveis foi realizada através do teste ANOVA e o teste de Tukey quando necessário. Resultados: As distâncias intercaninos, inter-segundospremolares e intermolares superiores apresentaram um maior aumento nos grupos Damon e ERM. Na arcada inferior, as larguras do arco mostraram um maior aumento no grupo Damon em comparação aos outros dois grupos. Houve uma maior protrusão dos incisivos superiores no grupo Damon em relação aos outros dois grupos. Nos incisivos inferiores, o Damon causou uma maior protrusão e vestibularização quando comparado com o grupo convencional. Conclusão: A forma do arco superior mostrou aumentos semelhantes na maioria das distâncias para o tratamento com o aparelho Damon e ERM com aparelhos convencionais. A forma do arco inferior mostrou maior aumento na maioria das distâncias medidas em casos tratados com o aparelho Damon, em comparação aos casos tratados com aparelho convencional, com e sem ERM. O aparelho Damon causou maior protrusão dos incisivos superiores. Nos incisivos inferiores o aparelho Damon causou uma maior protrusão e vestibularização quando comparado apenas com o aparelho convencional.Biblioteca Digitais de Teses e Dissertações da USPFreitas, Marcos Roberto deFurquim, Bruna Alves2015-03-05info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttps://www.teses.usp.br/teses/disponiveis/25/25144/tde-09112021-145429/reponame:Biblioteca Digital de Teses e Dissertações da USPinstname:Universidade de São Paulo (USP)instacron:USPLiberar o conteúdo para acesso público.info:eu-repo/semantics/openAccesseng2024-08-12T13:01:02Zoai:teses.usp.br:tde-09112021-145429Biblioteca Digital de Teses e Dissertaçõeshttp://www.teses.usp.br/PUBhttp://www.teses.usp.br/cgi-bin/mtd2br.plvirginia@if.usp.br|| atendimento@aguia.usp.br||virginia@if.usp.bropendoar:27212024-08-12T13:01:02Biblioteca Digital de Teses e Dissertações da USP - Universidade de São Paulo (USP)false |
