Elaboração de Próteses Auriculares Individualizadas por Meio de Manufatura Auxiliada por Computador
Resumo
O procedimento convencional de elaboração de próteses auriculares envolve o trabalho de um especialista que utiliza processos manuais para recriar a forma singular de uma orelha. Este é um processo lento, complexo e naturalmente pode ocasionar imperfeições. Este estudo apresenta um procedimento que, a partir de exames de imagem, utiliza técnicas computacionais de reconstrução, espelhamento e inversão de modelos tridimensionais para manufatura aditiva (impressão 3D) de moldes. Os resultados mostram que a prótese elaborada utilizando o processo exibe alto grau de realismo, apresentando 97,8% de similaridade dimensional comparada com a orelha sã do paciente.
