Introdução: O Socket Shield Technique (SST) envolve a manutenção de uma pequena porção da raiz vestibular com a inserção simultânea do implante numa posição mais palatina. Ao manter esta pequena porção da raiz no lado vestibular, a manutenção de uma quantidade igual de ligamento periodontal é garantida, evitando assim o desencadeamento dos eventos que normalmente acompanha as alterações volumétricas nos alvéolos pós-extração.
Objetivo: Avaliar a eficácia da SST para reduzir a reabsorção da placa óssea vestibular bem como a taxa de sobrevivência dos implantes comparado com a técnica convencional.
Materiais e Métodos: Foi desenvolvida uma pesquisa bibliográfica, com recurso às bases de dados PubMed, B-On e Cochrane Library que foi submetida a critérios de inclusão e exclusão. Os dados de cada publicação foram analisados, incluindo complicações, falha do implante, taxa de sobrevivência do implante e parâmetros clínicos (perda óssea marginal [POM], Pink esthetic score [PES], espessura óssea vestibular e reabsorção da placa óssea vestibular [RPOV]). Os dados coletados foram comparados para interpretação de resultados.
Resultados: De acordo com a pesquisa bibliográfica efetuada, foram encontradas 132 citações sobre o tema. Sobre 19 artigos em textos integrais estudados, foram incluídos 17 artigos e analisados nessa revisão sistemática. Nesta revisão, a taxa de sobrevivência do implante foi de 98,6% (9 implantes falhados em 656 implantes colocados). Nos estudos randomizados controlados, a POM foi significativamente menor nos implantes colocados com SST em comparação com os implantes colocados sem SST (SST 0.39±0.28 vs Controlo 1.00±0.55)
Conclusões: Todos os estudos incluídos nesta revisão sistemática demonstraram uma melhor preservação do osso marginal com o uso da SST. Ao analisar as complicações e as taxas de sobrevivência do implante com SST, podemos considerar essa técnica como uma alternativa bem-sucedida para implantes pós-extração em áreas estéticas. A presença do shield estabelece vantagens claras na preservação da margem tecidual vestibular, tanto para tecidos duros quanto para tecidos moles.
Introduction: Socket Shield Technique involves the maintenance of a small portion of the vestibular root with simultaneous insertion of the implant in a more palatal position. By maintaining this small portion of the root on the vestibular side, the maintenance of an equal amount of periodontal ligament is guaranteed, thus avoiding the triggering of the chain of events that normally accompanies the volumetric changes in the post-extraction alveoli. Objective: To evaluate the effectiveness of SST to reduce buccal bone plate resorption as well as the implant survival rate compared to the conventional technique. Materials and Methods: A bibliographic research was developed, using databases PubMed, B-On e Cochrane Library that was submitted to inclusion and exclusion criteria. Data from each publication were analyzed, including complications, implant failure, implant survival rate, and clinical parameters (marginal bone loss [POM], pink esthetic score [PES], vestibular bone thickness, and vestibular bone plate resorption [POPR]). The collected data were compared for interpretation of results. Results: According to the bibliographic research carried out, 132 citations on the subject were found. Regarding 19 articles in full texts studied, 17 articles were included and analyzed in this systematic review. In this review, the implant survival rate was 98.6% (9 failed implants out of 656 implants placed). In randomized controlled trials, POM was significantly lower in implants placed with SST compared to implants placed without SST (SST 0.39±0.28 vs Control 1.00±0.55). Conclusions: All studies included in this systematic review demonstrated a better preservation of marginal bone with the use of OSH. When analyzing the complications and survival rates of the implant with TSS, we can consider this technique as a successful alternative to post-extraction implants in aesthetic areas. The presence of the shield establishes clear advantages in the preservation of the vestibular tissue margin, both for hard and soft tissues. Keywords: socket, socket shield, socket shield technique, root membrane technique, implant placement, alveolar ridge preservation, implant proximity to teeth and implant in contact with root.
