Abstract(s)
Reabilitar zonas edêntulas com implantes dentários tornou-se uma prática muito comum nos dias de hoje, sendo imprescindível avaliar a quantidade e qualidade óssea existente. Quando a zona do maxilar posterior se encontra edêntula por um longo período de tempo, uma pneumatização do seio maxilar poderá ocorrer bem como uma reabsorção do rebordo alveolar. Nestes casos é comum recorrer-se a técnicas de elevação do seio de forma a aumentar verticalmente o osso residual recorrendo a materiais de enxerto ósseo cuja função é fornecer osso viável para estabilizar o implante e favorecer a sua osteointegração.
Nesta monografia foram comparadas duas técnicas de elevação do seio maxilar, a Técnica de Janela Lateral e a Técnica Transalveolar, a fim de concluir qual a mais indicada consoante a altura óssea residual presente bem como avaliar a taxa de sobrevivência de implantes colocados após a aplicação de cada técnica.
Rehabilitating edentulous areas with dental implants is a very common practice nowadays and it is essential to assess the quantity and quality of residual bone. When the posterior maxillary area is edentulous for a long period of time, a pneumatization of the maxillary bone may occur as reabsorption of the alveolar ridge. In these cases, it is very common to resort to bone elevation techniques in order to vertically increase the residual bone using bone graft materials whose function is to provide a viable bone to stabilize the implant and lead to osseointegration. In this monograph two techniques of maxillary bone elevation were compared, the Lateral Window Technique and the Transalveolar Technique, to see which one is more indicated based on the residual bone height as well as to assess the implant’s survival rate that was placed after each technique.
