Abstract

This report describes the combination of analog and digital techniques for the fabrication of a 2-piece hollow bulb maxillary obturator. The procedure described provides an accurate representation of the surgical defect while avoiding the discomfort associated with analog impressions. The manipulation of a routine postoperative computed tomography (CT) scanner in conjunction with a 3D printer allowed for the fabrication of a 3D-printed anatomic cast from which the 2-piece hollow bulb obturator was fabricated. The clinical and laboratory steps involved are described in this article.
