Resumo

INTRODUÇÃO: A radioterapia de tumores na região de cabeça e pescoço causa uma série de efeitos adversos. Alguns desses efeitos são temporários, como mucosites e diugesia; e outros permanentes, como xerostomia, risco a ostorradionecrose e risco a cáries. Uma das formas de diminuir os efeitos colaterais da radioterapia é diminuir a dose de radiação de estruturas saudáveis fora da área do tumor através de técnicas radioterápicas mais precisas como a radioterapia de intensidade modulada (IMRT) a qual depende de posicionadores e estabilizadores das estruturas anatômicas.
RELATO DO CASO: O presente artigo demonstra exemplos de confecção direta de abridores de boca e posicionadores de língua e mandíbula que permitem o afastamento das estruturas saudáveis bem como a estabilização precisa necessária à técnica do IMRT.
CONCLUSÃO: Os casos clínicos apresentados no presente artigo também ilustram que os dispositivos intraorais para estabilização das arcadas dentárias e da língua são eficientes em diminuir a dose de radiação desnecessária a estruturas saudáveis.
