Efeito das reabilitações bucais na eficiência de ciclos mastigatórios - Análise eletromiográfica por meio da integral da envoltória / Effect of Oral Rehabilitation at the efficiency of Masticatory Cycles - Electromyographic Analysis by Means of Integral Envelopment.

Cristiane Savaris 25 February 2011 (has links)
A perda dental determina importantes alterações no sistema estomatognático, dentre elas, a redução da performance mastigatória, uma vez que esta é dependente das condições da dentição do indivíduo. Dessa forma, o restabelecimento da função tem grande importância em pacientes reabilitados com próteses bucais. No presente estudo, foram analisados indivíduos adultos reabilitados com diferentes tipos de próteses bucais, com o objetivo de verificar a influência do tipo de reabilitação protética na eficiência dos ciclos mastigatórios por meio da integral da envoltória da atividade eletromiográfica na mastigação habitual de amendoins e uvas passas e na mastigação não-habitual com Parafilme. Participaram desta pesquisa 50 indivíduos divididos em cinco grupos de acordo com o tipo de reabilitação protética. Cada grupo foi constituído por 10 indivíduos: Grupo I portadores de implantes e coroas unitárias; Grupo II portadores de Prótese Total maxilar e Overdenture mandibular sobre implantes; Grupo III portadores de Prótese Total maxilar e mandibular; Grupo IV portadores de Prótese Parcial Removível maxilar e mandibular e Grupo V - indivíduos dentados totais (grupo controle). Neste estudo a eficiência do ciclo mastigatório foi analisada por meio da integral da envoltória do sinal eletromiográfico (microvolts/segundo). Os sinais eletromiográficos foram obtidos na mastigação habitual de amendoins e de uvas passas sem sementes, durante vinte segundos e na mastigação não habitual de Parafilme M® durante dez segundos. Os dados da mastigação foram analisados usando ANOVA e Teste de Duncan (p≤0,05). Os resultados evidenciaram menores valores eletromiográficos para indivíduos dentados totais em todas as condições clínicas avaliadas, seguido do grupo portador de implantes com coroas unitárias. Pode-se concluir que a eficiência dos ciclos mastigatórios foi influenciada pelo tipo de reabilitação protética bucal. / The tooth loss causes important changes in the stomatognathic system, among them the reduction of masticatory performance, since this is dependent on the conditions of a person\'s teeth. Thus, the restoration of function has great importance in patients rehabilitated with oral implants. In this study, we analyzed adult individuals rehabilitated with different types of denture, with the objective of verifying the influence of prosthetic rehabilitation in the efficiency of the cycles by means of the integral of the envelope of EMG activity in the mastication of peanuts and raisins and non-habitual chewing with Parafilm. The sample was 50 individuals, divided into five groups according to the type of prosthetic rehabilitation. Each group comprised 10 individuals: Group I - patients with implants and crowns, Group II - patients with maxillary denture and mandibular overdentures on implants, Group III - patients with maxillary and mandibular denture Group IV - patients with Partial Denture Removable maxillary and mandibular and Group V - dentate subjects (control group). In this study the efficiency of the masticatory cycle was analyzed by the integral of the signal envelope EMG (microvolts / second). The signals were obtained in the mastication of peanuts and raisins without seeds, for twenty seconds and chewing Parafilm unusually for ten seconds. Data of chewing were analyzed using ANOVA and Duncan Test (p≤0.05). The results showed lower EMG values for individuals dentate in all clinical conditions assessed, followed by the group with implants with crowns. It can be concluded that the efficiency of the cycles was influenced by the type of oral prosthetic rehabilitation.

Avaliação ultrassonográfica da musculatura do sistema estomatognático em indivíduos com disfunção temporomandibular muscular / Ultrasound evaluation the muscle stomatognathic system in individuals with temporomandibular disorder muscle

Antuanett Mercedes Cornejo Lecaros 16 August 2012 (has links)
A disfunção temporomandibular (DTM) engloba as alterações relacionadas com as articulações temporomandibulares (ATMs), a musculatura mastigatória e demais estruturas do sistema estomatognático apresentando-se na forma de dores nos músculos da mastigação, ATMs, músculos cervicais, reduções e desvios nos movimentos da mandíbula, sons articulares e padrões de oclusão inadequados. É de relevante importância estudar a musculatura mastigatória por causa da grande influência que a mesma tem no sistema estomatognático. O objetivo deste estudo foi analisar a espessura do músculo masseter e temporal, bilateralmente, por meio da ultrassonografia em indivíduos portadores de DTM muscular, com a finalidade de definir o padrão de espessura muscular nesta disfunção. Os resultados deste estudo permitiram a avaliação do sistema estomatognático do ponto de vista funcional em indivíduos portadores de DTM muscular e poderão nortear o cirurgião dentista na elaboração de diagnósticos, prognósticos e planos de tratamento, com ganho de qualidade de vida para seus pacientes. Portanto conclui-se que na condição de repouso como no apertamento em máxima intercuspidação habitual houve uma diminuição da espessura do músculo masseter esquerdo, temporal direito e esquerdo para o grupo com DTM muscular. E com relação ao gênero houve uma diminuição da espessura muscular, tanto para o músculo masseter quanto para o músculo temporal, nas mulheres. / The temporomandibular disorders (TMD) includes changes related to the temporomandibular joints (TMJ), masticatory muscles and other structures of the stomatognathic system presents itself as pain in the masticatory muscles, joints, cervical muscles, cuts and deviations in the movements of jaw joint sounds and patterns of inadequate occlusion. It is of major importance to study the masticatory muscles because of the great influence which it has in the stomatognathic system. The objective of this study was to analyze the thickness of the masseter and temporal bilaterally by ultrasonography in patients with TMD muscle, in order to set the standard for this thick muscle dysfunction. The results of this study will allow assessment of the stomatognathic system\'s functional point of view in individuals with TMD muscle and can guide the dentist in making diagnoses, prognoses and treatment plans, with gains in quality of life for their patients. Therefore it is concluded that at rest as in clenching in maximum intercuspation was a thinning of the left masseter, temporalis left and right for the group with muscular TMD. And with respect to gender there was a decrease in muscle thickness for both the masseter and temporalis muscle for in women.
