Abstract(s)
Os implantes dentários são uma opção de tratamento possível quando há quantidade e qualidade suficientes de rebordo ósseo. Todavia, quando os pacientes apresentam cristas alveolares deficientes, a execução deste procedimento pode ser prejudicada. Este defeito é especialmente ampliado na maxila posterior onde ocorre a reabsorção e pneumatização dos seios maxilares, conciliada com uma má qualidade do osso. O procedimento que é frequentemente escolhido e que possibilita a reconstrução desta área com deficiência anatómica, é o levantamento de seio maxilar. Para a integração do implante dentário o volume e densidade do osso alveolar são alguns dos requisitos que devem ser considerados para obter um bom resultado clinico. A elevação do Seio maxilar pela técnica de janela lateral de Cadwell-Luc é um procedimento que tem vindo a ser bastante utilizado. A abordagem desta técnica resume-se basicamente a um acesso cirúrgico através da parede medial do seio maxilar, seguida da elevação da membrana do seio maxilar e posteriormente a colocação do material de enxerto ósseo. Neste trabalho o material escolhido para analise, foi o enxerto de origem humana denominado “autógeno”. O objetivo desta pesquisa é analisar e resumir a cirurgia para levantamento do pavimento do seio maxilar pela técnica de janela lateral voltada à reconstrução de atrofia óssea na maxila provocada por aumento do volume de seio maxilar. O levantamento do seio maxilar, por meio de procedimento cirúrgico, possibilita num período de seis meses a colocação de futuros implantes osteointegrados na região posterior da maxila. Este procedimento cirúrgico vem sendo praticado com certa frequência no campo da implantologia oral, a fim de futuramente possibilitar a reabilitação estética e funcional na cavidade oral do paciente.
Dental implants are a possible treatment option when there is sufficient quantity and quality of bony ridge. However, when patients manifest deficient alveolar ridges, the execution of this procedure may be impaired. This defect is especially enlarged in the posterior maxilla where the reabsorption and pneumatization of the maxillary sinuses occurs, reconciled by poor bone quality. The procedure that is frequently chosen and that allows the reconstruction of this anatomically deficient area is the maxillary sinus lift. For the integration of the dental implant, the volume and density of the alveolar bone are some of the issues that must be considered in order to obtain a good clinical result. Elevation of the maxillary sinus by the lateral window technique of Cadwell-Luc is a procedure that has been widely used. The approach of this technique is basically a surgical approach through the medial wall of the maxillary sinus, followed by elevation of the maxillary sinus membrane and posteriorly the placement of the bone graft material. In this work the material chosen for analysis was the graft of human origin called "autogenous". The objective of this research is to analyze and summarize surgery for maxillary sinus floor lift by the lateral window technique aimed at the reconstruction of maxillary bone atrophy caused by increased maxillary sinus volume. The maxillary sinus lift, through a surgical procedure, allows the installation of future osseointegrated implants in the posterior region of the maxilla over a period of six months. This surgical procedure has been practiced with some frequency in the field of oral implantology, in order to allow future aesthetic and functional rehabilitation in the oral cavity of the patient.
