Prótese Auricular, Manufatura Aditiva, Tecnologias Digitais, ReabilitaçãoResumo
O artigo apresenta uma revisão de escopo das metodologias, tecnologias e resultados associados ao uso da manufatura digital na produção de próteses auriculares, destacando seu impacto transformador na reabilitação auditiva, bem como os desafios atuais e as perspectivas para o desenvolvimento e a disseminação dessa tecnologia. Para isso, foi conduzida uma revisão de escopo com 44 artigos. Os resultados demonstraram a transição para fluxos digitais de trabalho, com o método direto sendo empregado em 55% dos estudos. Essa abordagem tem permitido a criação de próteses mais precisas, eficientes e de baixo custo, resultando em maior satisfação do paciente. A transição para a produção digital de próteses auriculares é um avanço promissor que tem o potencial de superar os desafios da fabricação convencional. A evolução das tecnologias de escaneamento, impressão 3D, softwares de código aberto e o uso de novos materiais tornarão os processos mais acessíveis e eficientes.
