Abstract
Digital workflows have been used in the oral rehabilitation of patients with maxillofacial defects. However, dental techniques for fabricating a denture obturator for patients with a total maxillectomy are lacking. This technical report describes the use of digital technology to produce a milled complete denture obturator using an intraoral scanner, a computer-aided design software program, and computer-aided manufacturing. The limited size of the milled polymethylmethacrylate disk was resolved by separating the prosthesis into 3 pieces: the obturator base, denture base, and artificial teeth.
