Pinos de fibra de vidro anatômicos: aspectos adesivos e mecânicos – revisão de literatura
Resumo
O objetivo desse estudo foi realizar uma revisão de literatura sobre a resistência de união de pinos de fibra de vidro anatômicos (PFVA). Foi realizada busca por artigos na base eletrônicas de dados (PubMed/Medline, Bireme e Scielo) entre os anos 2000 e 2019, utilizando as palavras chave: pinos (posts), pinos de fibra (fiber posts), resistência de união (bond strength) e retenção (retention). Após isso, os resumos dos estudos foram selecionados de acordo com o tema proposto, baixados e lidos para inserir no trabalho somente os pontos principais de cada trabalho e, assim, formular a revisão de literatura com informações atuais. PFVA apresentam maior resistência de união quando comparados a PFVC, principalmente pela diminuição da linha de cimentação, que representa o ponto mais fraco da adesão. Diante disso é indicado o uso de PFVA na prática clínica, como uma opção de restauração segura, uma vez que a distribuição das tensões será mais uniforme, evitando a fratura de estruturas fragilizadas, que podem resultar na perda do elemento dentário.
