Simplifying the digital workflow of facial prostheses manufacturing using a three-dimensional (3D) database: setup, development, and aspects of virtual data validation for reproduction.

Purpose: To set up the digital database (DDB) of various anatomical parts, skin details and retention elements in order to simplify the digital workflow of facial prostheses manufacturing; and to quantify the reproduction of skin wrinkles on the prostheses prototypes with stereolithography (SLA) and direct light processing (DLP) methods.

Methods: Two structured light scanners were used to obtain the nasal and auricle forms of 50 probands. Furthermore, the ala nasi and scapha areas were captured with the digital single lens reflex camera and saved in jpeg format.

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

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.

Auricular Prostheses Produced by Means of Conventional and Digital Workflows: A Clinical Report on Esthetic Outcomes.

The utilization of additive manufacturing (AM) technology for the production of auricular prostheses has been widely acknowledged. However, few studies and case history reports have evaluated the esthetic outcomes of AM prostheses compared to those of conventionally manufactured prostheses. In this case history report, three manufacturing approaches-conventional, indirect, and direct mold preparation-were assessed for their esthetic outcomes in the same patient.
