This work aims to define an accessible workflow for the design and manufacturing of maxillofacial obturator prostheses from DICOM files for patients with reduced mobility of the oral cavity. Starting from a case study, the STL file of the injured area was generated to develop the parametric 3D model of the mold. The mold was then manufactured with a low-cost 3D printer, and the palatal obturator was obtained by silicone casting. The patient has improved his quality of life by recovering some vital functions. This workflow may overcome conventional processes, leading to develop new patient-specific prostheses in critical situations.

Abstract

This work aims to define an accessible workflow for the design and manufacturing of maxillofacial obturator prostheses from DICOM files for patients with reduced mobility of the oral cavity. Starting from a case study, the STL file of the injured area was generated to develop the parametric 3D model of the mold. The mold was then manufactured with a low-cost 3D printer, and the palatal obturator was obtained by silicone casting. The patient has improved his quality of life by recovering some vital functions. This workflow may overcome conventional processes, leading to develop new patient-specific prostheses in critical situations.
