This article describes a digital workflow for fabricating an interim obturator after partial maxillectomy which utilizes the radiopacity of iodoform gauze, a common surgical packing material, to simulate postoperative oronasal defect cavities through a computer-aided design and computer-aided manufacturing (CAD-CAM) workflow and to generate the interim obturator by 3-dimensional printing. This technique may serve as a promising alternative technique for the fabrication of an interim obturator and, in particular, benefit patients who have not seen a prosthetic specialist before surgery and present without a surgical obturator.
