Use of open‐source software and photogrammetry in the fabrication of 3D‐printed custom trays for edentulous patients: A technical guide

Abstract A technique is described to obtain a 3D‐printed custom tray for complete dentures through open‐source, free software and additive manufacturing. This approach enables the production of custom trays in a cost‐effective and optimized manner. A three‐dimensional (3D) digital cast is obtained by photogrammetry and later used to design a digital custom tray. Then, the digital custom tray is manufactured by a 3D printer to be used in clinical procedures. This technique is a clean, rapid, and low‐cost alternative to the traditional technique.
