Fabrication of obturator prosthesis by fusing CBCT and digital impression data

This clinical report describes a digital workflow using an intraoral digital impression and cone beam computed tomography (CBCT) volumetric data to create a three-dimensional (3D) virtual model of the dentition, defect area, and soft and hard tissue of a patient who had undergone a hemimaxillectomy. Stereolithography (SLA) 3D printing technology was used to produce a resin mold, from which an obturator prosthesis was fabricated through a conventional technique.
