Abstract(s)
A região maxilar posterior edentula representa um desafio à reabilitação oral com implantes, dada a perda de volume ósseo vertical, predominância de osso de baixa densidade e ao processo de pneumatização do seio maxilar que ocorre ao longo do tempo, em consequência da reabsorção óssea alveolar. Estas alterações dentárias são bastante frequentes e requerem resolução precedente à colocação de implante na região maxilar posterior dado que comprometem a estabilidade do implante. A elevação do seio maxilar é praticamente um procedimento padrão de exigível precedência à intervenção implanto-cirúrgica. Esta revisão narrativa da literatura descreve o estado da arte quanto à aplicabilidade destas diferentes abordagens que são: abordagem de janela lateral e abordagem transcrestal. Cada uma com suas vantagens e desvantagens, indicações e complicações. A pesquisa bibliográfica que sustenta esta revisão narrativa inclui os artigos científicos publicados na última década na base de dados Pubmed com a seguinte conjugação de termos [title]: sinus AND lift AND (transcrestal OR lateral maxillary OR maxillary). Dos trinta um artigos resultantes desta pesquisa foram incluídos, após análise dos seus conteúdos, treze artigo s dado sua consonância com os propósitos que fundam esta revisão de literatura. A esta pesquisa acresceu se uma busca livre em livros e outros artigos científicos com a intensão de angariar um contributo adicional para o esclarecimento do assunto em revisão narrativa. Atualmente, estão disponíveis abordagens odontológicas de elevação do seio maxilar de comprovado sucesso: a abordagem de janela lateral e a abordagem transcrestal.
The edentulous posterior maxillary region represents a challenge to oral rehabilitation with endosseous implants given the loss of vertical bone volume, predominance of low density bone and the process of pneumatization of the maxillary sinus that occurs over time as a result of alveolar resorption. These dental alterations are quite frequent and require re solution prior to implant placement in the posterior maxillary region, as they compromise the stability of the implant an essential condition for successful implant placement. Maxillary sinus elevation is practically a standard procedure that takes precedence over the dental intervention of endosseous implantology. This narrative literature review describes the state of the art regarding the applicability of these different approaches: each one with its advantages and disadvantages, indications and complications. The bibliographic research that supports this narrative review includes scientific articles published in the last decade in the Pubmed database with the following conjugation of terms [title]: sinus AND lift AND (transcrestal OR lateral maxillary OR maxillary). Of the thirty one articles resulting from this research, thirteen articles were included, after analyzing their contents, given their consonance with the purposes underlying this literature review. A free search in books and other scientific articles was added to this research with the intention of raising an additional contribution to the clarification of the subject in a narrative review. Maxillary sinus lift dental approaches are currently available and successful: the lateral window approach and the transcrestal approach.
