Previsibilidade das alterações do tecido mole em indivíduos dolicofaciais /

Sakima, Patricia Panizzi Gimenes. January 2006 (has links)
Orientador: João Roberto Gonçalves / Banca: Ronald de Freitas Paixão / Banca: Darceny Zanetta Barbosa / Banca: Luiz Gonzaga Gandini Júnior / Banca: Ary dos Santos Pinto / Resumo: As alterações do tecido mole, após tratamento ortodôntico-cirúrgicos, têm sido muito estudadas. Entretanto, a ausência de homogeneidade da amostra, a não consideração da direção do movimento cirúrgico dos maxilares e a utilização de proporções podem levar a informações imprecisas do movimento do tecido mole em relação ao tecido duro. Assim, avaliou-se alterações labiais de indivíduos leucodermas, verticais, portadores de má oclusão de Classe II, que haviam sido submetidos a cirurgia bimaxilar com rotação anti-horária do plano oclusal. Foram utilizadas telerradiografias em norma lateral, uma pré-cirúrgica imediata e outra pós-cirúrgica tardia de cada um dos 24 indivíduos pertencentes à amostra. Traçados cefalométricos foram realizados e digitalizados no programa cefalométrico Dentofacial Planner Plus versão 2,02. Constatou-se movimento anterior e superior dos tecidos duro e mole, além de alteração do comprimento e da espessura do lábio inferior. No teste de regressão múltipla foi observado o envolvimento de diversas variáveis na alteração dos lábios superior e inferior. Houve relação entre as respostas labiais e as alterações posicionais do tecido duro e morfológicas do tecido mole. Foram estabelecidas equações para predição dos movimentos horizontal e vertical de ambos os lábios em função destas alterações. / Abstract: Soft tissue changes after orthodontic-surgery treatments have been already studied. However sample heterogeneity, non consideration of the direction of the surgical movement and the proportions to predict the soft tissue movements can lead to imprecise information of the soft tissue movement in relation to the hard tissue. Thus, the lips responses of vertical Class II white patients submitted to double jaw surgery with counter clockwise rotation were evaluated in a sample composed by 24 immediate pre surgical and 24 late post-surgical lateral cephalograms. Each pair of cephalograms was traced and digitized in the Dentalfacial Planner 2,02. The radiographic amplifications were corrected by the same software. Anterior and superior movements of the hard and soft tissues and length and thickness changes of the lower lip occurred. Multiple regression models showed that several variables influenced lips alterations. The lips responses were related to the positional changes of the hard tissue and the morphological alterations of the soft tissue. The prediction equations for horizontal and vertical movements of the lips were established. / Doutor
