No. of bitstreams: 1 Sonoda_HumbertoMassaru_D.pdf: 2523666 bytes, checksum: a837644195a81c0eb1bcd8bbdd12061f (MD5) Previous issue date: 2010 / Resumo: O objetivo deste estudo foi avaliar clínica e eletromiograficamente a eficácia dos aparelhos oclusais planos em pacientes dentados, sem as guias anteriores (incisivos e caninos), com desordens temporomandibulares (DTM) de origem miogênica, e estabelecer, se possível, correlação entre os dois métodos de avaliação, além de investigar o efeito deste tipo de aparelho sobre o espaço funcional livre (EFL). Foram examinados dezenove pacientes de ambos os sexos, com idades entre 18 e 59 anos. As avaliações clínicas foram realizadas com auxílio de uma escala visual analógica (EVA) antes da instalação dos aparelhos oclusais planos (tempo zero - T0), após 30, 60 e 90 dias. No tempo 30 (T30), os aparelhos foram alterados e, sobre eles confeccionadas as guias anteriores. As avaliações eletromiográficas realizadas sobre os músculos temporais anteriores e masseteres foram obtidas antes e aos 30 e 60 dias da instalação dos aparelhos. Os resultados mostraram que ocorreram diferenças significativas entre os dados obtidos com a EVA nos diferentes tempos de avaliação (ANOVA; p<0,001), principalmente entre T0, T30 e T60. Além disso, se observou que o espaço funcional livre dos pacientes foi significantemente superior, em média, no T90 comparado ao T0 (teste t de Student; p<0,001). Os registros eletromiográficos revelaram valores variáveis entre os músculos estudados nos diferentes tempos de avaliação, porém na maioria deles, as diferenças não foram significantes (p>0,05), sugerindo que a melhora clínica da sintomatologia, não necessariamente foi acompanhada de uma redução da atividade eletromiográfica dos músculos envolvidos. / Abstract: The purpose of this study was to evaluate clinical and electromyographically, the effectiveness of the flat occlusal splints in dentate subjects, without the incisor and canine guidances, with signs and symptoms of myogenic temporomandibular disorders (TMD), and establish a correlation between the two methods of assessment, besides to investigate the effect of this appliance over the free-way space (FWS). Nineteen patients of both genders, aged between 18 and 59 years were examinated. The clinical evaluations were accomplished through a Visual Analogyc Scale (VAS) before the installation of the flat occlusal splints (zero time - T0), after 30, 60 and 90 days. At time 30 (T30), the splints were altered by placing the incisor and canine guidance over them. The electromyographic evaluations were realized on the anterior temporal muscles and masseter muscles, before the beginning of the treatment, 30 and 60 days after using the flat occlusal splints. The results revealed significant differences between the data obtained with VAS at different times of evaluation (ANOVA; p < 0,001), mainly between T0, T30 and T60. Moreover, it was observed that the free-way space of the patients was significantly higher, as a rule, at T90 than T0 (Student's t test; p< 0,001). The electromyographic records revealed variable values between the studied muscles at different times of evaluation, however, in most of them, the differences were not significant (p>0,05), suggesting that the clinical improvement of symptomatology, not always was attended by decreasing of the electromyographic activity of the involved muscles. / Doutorado / Protese Dental / Doutor em Clínica Odontológica

No. of bitstreams: 1 Vera_RosarioMarthadeLaTorre_M.pdf: 1075530 bytes, checksum: ef0a17b37af765f47297af2d3ddf9673 (MD5) Previous issue date: 2010 / Resumo: As deformidades dentofaciais são alterações dos tecidos duros e moles que podem ser resultado da influência genética ou ambiental. A cirurgia ortognática possibilita a correção cirúrgica das deformidades dentofaciais e sua importância se dá não apenas pela correção da oclusão e da funcionalidade, mas também pela melhora da estética facial. Os objetivos foram (1) avaliar aspectos funcionais (atividade eletromiográfica) em diferentes momentos em repouso e na contração voluntária máxima (isometria) (2) Avaliar a presencia da sintomatologia dolorosa pré e pós-tratamento cirúrgico (3) Avaliar a simetria dos músculos da mastigação em diferentes movimentos mandibulares (isotonia e isometria) em pacientes classe III de Angle. Para a avaliação da sintomatologia dolorosa foi utilizado o questionário RDC/TMD o eixo I e II, posteriormente foi realizado o exame eletromiográfico com a finalidade de registrar a atividade do músculo masseter e da parte anterior do músculo temporal bilateralmente durante o repouso, isotonia e a isometria. Após a análise qualitativa do sinal, as variáveis de estudo foram: Amplitude (Root Mean Square (RMS)) e a simetria muscular estas avaliações foram realizadas pré tratamento (2 a 3 meses) e pós tratamento cirúrgico ( 2 e 6 meses) pós cirurgia ortognática. Este trabalho foi realizado em dois capítulos diferentes onde os resultados e conclusões mostram que a cirurgia ortognática tem um efeito de melhora de alguns sintomas e sinais das DTM pós tratamento cirúrgico para pacientes com prognatismo mandibular, também este tipo de tratamento cirúrgico influencia na mudança dos padrões do sinal eletromiográfico onde a variável simetria melhora nas diferentes posturas mandibulares após a cirurgia, em pacientes classe III de Angle (dentoesqueletica) / Abstract: Dentofacial deformities are alterations in hard and soft tissues that cold be result from genetic or environmental influences. Orthognathic surgery aims to demonstrate the improvement of the esthetic and functional deficits after surgery. The objectives were (1) to assess physical and funcional activity (EMG) in rest and isometric (2) evaluate the presence of painful symptoms before and after surgery (3) to assess the symmetry of masticatory's muscles in different jaw movements (isotonic and isometric). For the evaluation of painful symptoms was used questionnaire RDC / TMD axis I and II. The electromyographic were performed in all patients in the masseter and temporal muscles bilaterally during rest, isotonic and isometric. After the qualitative analysis of the signal, the variables were selected are: amplitude (Root Mean Square (RMS)) and Symmetry. These assessments were performed before treatment (2 to 3 months) and after surgical treatment (2 and 6 months). This study was conducted in two separate chapters where the results and conclusions show that in orthognathic surgery has a significant improvement in symptoms and signs of TMD after surgical treatment for patients with mandibular prognathism and orthognathic surgery also influences the changing patterns electromyographic signal and the variable symmetry improvement in different positions after mandibular surgery in patients class III of Angle / Mestrado / Anatomia / Mestre em Biologia Buco-Dental
