Associação de membrana de colágeno e fibrina rica em plaquetas (PRF) em cirurgia de regeneração óssea guiada na região posterior de mandíbula

RESUMO

A regeneração óssea guiada (ROG) é o método mais utilizado para aumento ósseo antes da cirurgia de implante dentário. Uma paciente do sexo feminino, com 55 anos de idade, apresentou dor e inchaço na mandíbula posterior. Após análise clínica e tomográfica de feixe cônico, indicou-se a extração dos dentes 37 e 38. Foi realizada a colocação de implantes dentários nas posições dos dentes 36, 37 e 38, associada à regeneração da parede óssea lingual. A combinação da regeneração óssea guiada realizada simultaneamente com a colocação de implantes na mandíbula posterior, utilizando uma membrana de colágeno em conjunto com fibrina rica em plaquetas, proporcionou resultados satisfatórios em termos de reconstrução óssea e reabilitação com implantes, conforme evidenciado por um período de acompanhamento de 36 meses.

Palavras-chave – Regeneração óssea guiada; Implante dentário imediato; Fibrina rica em plaquetas.

ABSTRACT

Guided bone regeneration (GBR) is a widely employed technique for bone augmentation preceding dental implant surgery. A 55-years-old female patient presented pain and swelling in the posterior mandible. Following a clinical and tomographic assessment, the extraction of teeth 37 and 38 was deemed necessary. Dental implant placement in the position of teeth 36, 37, and 38 was carried out, associated by the regeneration of the lingual bone wall. The combination of guided bone regeneration performed simultaneously with implant placement in the posterior mandible, employing a collagen membrane in conjunction with platelet-rich fibrin, showed favorable outcomes in terms of bone reconstruction and implant-supported rehabilitation, as evidenced by a 36-month follow-up period.

Key words – Guided bone regeneration; Immediate dental implant; Platelet-rich fibrin.
