Elaboração de Próteses Auriculares Individualizadas por Meio de Manufatura Auxiliada por Computador
Abstract
The standard procedure of auricular prosthesis design involves the work of an expert using manual processes to recreate the complex shape of an ear. This is a slow and complex process that naturally lead to imperfections. This study presents a procedure that, from imaging exam uses computational techniques of reconstruction, mirroring and inversion of three-dimensional models for additive manufacturing (3D printing) of molds. The results show that the designed prosthesis using the process has a high level of realism, with 97.8% of similarity compared to healthy ear of the patient.
