Direct 3D printing of silicone facial prostheses: A preliminary experience in digital workflow

摘要

Direct silicone printing may be applied to the fabrication of maxillofacial prostheses, although its clinical feasibility is unknown. The present clinical report shows an early application of a directly printed silicone prosthesis for the rehabilitation of a nasal defect. Two extraoral scanning systems were used to capture the face and the defect. The virtual construction of the nasal prosthesis was performed with free-form software. Two prostheses were printed in silicone and post-processed by manual sealing and coloring. The clinical outcome was acceptable for an interim prosthesis; however, the marginal adaptation and color match were not satisfactory without further individualization.
