Purpose: Patients with maxillofacial deformities always seek for aesthetic prosthesis. Recently, three-dimensional printing technologies have been used for dental treatments on such patients. Case report: A 24-year-old man reported to the Department of Prosthodontics for replacement of his missing right ear induced by a trauma. A magnet-retained auricular prosthesis was planned for the patient. Three-dimensional scanning was performed on the healthy side by using a three-dimensional optical scanner and the data were mirrored. The mirrored image was then imported to a software and a virtual model of the future prosthesis was obtained for the defect side. A three-dimensional printer was used to fabricate a negative mold for the mirrored image by using additive manufacturing. Initially, an impression of the defect side was made; then, the cast model was obtained in a dental flask. Magnets of the prosthesis were inserted to the acrylic resin framework on the cast model. Room temperature vulcanized silicone elastomer was mixed and poured into the three-dimensionally fabricated mold. Then, the flask was placed over the negative mold firmly. After polymerization of the silicone, the auricular prosthesis was delivered to the patient and the patient was instructed to clean the prosthesis daily. Conclusions: Three-dimensional printing technology was used for the fabrication of the patient's missing ear. This method eliminated the conventional laboratory steps and reduced the number of stages of the fabrication of a silicone prosthesis. The negative mold of the defect side allowed us a direct fabrication of the silicone prosthesis without a need for waxing or flasking procedures.
