Resumo: | Introduction: This study aimed to cephalometrically compare the dentolalveolar, skeletal and soft tissue changes caused by Jones jig, Distal jet and First Class appliances. Methods: The sample included 71 patients divided into three groups. G1 (n=30; 16 male, 14 female, with a mean age of 13.17 years) was treated with Jones jig for 0.8 years. G2 (n=25; 8 male, 17 female, with a mean age of 12.57 years) was treated with Distal jet for 1.06 years. G3 (n=16; 6 male, 10 female, with a mean age of 12.84 years) was treated with First Class for 0.69 years. Intergroup treatment changes comparisons were performed using one-way ANOVA followed by Tukey tests. Results: Intergroup comparisons showed significantly greater maxillary premolar mesial angulation and first molar distal angulation in G1. The maxillary first molars presented smaller distal angulation in G2. G3 presented significantly smaller first premolar mesialization compared to G1 and smaller incisor protrusion and less overjet change compared to G2. Treatment time was significantly smaller in G3. Conclusion: All appliances corrected the Class II molar relationship. The Distal jet group produced smaller distal angulation. First Class appliance seems to produce less anchorage loss and shorter treatment time. |

Métodos: Foram avaliados 71 pacientes divididos em três grupos. G1 (n=30; 16 homens, 14 mulheres, idade inicial de 13.17 anos) foi tratado com o aparelho Jones jig durante 0.8 anos. G2 (n=25; 8 homens, 17 mulheres, idade média inicial de 12.57 anos) foi tratado com o aparelho Distal jet durante 1.06 anos. G3 (n=16; 6 homens, 10 mulheres, idade média inicial de 12.84 anos) foi tratado com o aparelho First Class durante 0.69 anos. Para comparar as alterações entre os grupos utilizou-se o ANOVA a um critério seguido do teste Tukey. Resultados: G1 apresentou significativamente maior angulação mesial dos pré-molares e distal do primeiro molar superior. G2 demonstrou menor angulação distal do primeiro molar superior em relação aos outros grupos. G3 apresentou menor mesialização dos primeiros pré-molares em relação a G1 e menor protrusão dos incisivos com consequente menor aumento da sobressaliência em relação a G2. O tempo de tratamento foi significativamente menor em G3. Conclusão: Todos os grupos foram eficientes na correção da relação molar. Distal jet produz menor angulação distal do primeiro molar superior. First Class parece produzir menor movimento mesial dos dentes de ancoragem e menor tempo de tratamento.Biblioteca Digitais de Teses e Dissertações da USPHenriques, Jose Fernando CastanhaSouza, Lorena Vilanova Freitas de2017-03-06info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttps://www.teses.usp.br/teses/disponiveis/25/25144/tde-25102021-182309/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/openAccesseng2024-08-12T14:12:02Zoai:teses.usp.br:tde-25102021-182309Biblioteca 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:27212024-08-12T14:12:02Biblioteca Digital de Teses e Dissertações da USP - Universidade de São Paulo (USP)false |
