Abstract

A digital workflow was used to design and prefabricate a 3-dimensionally printed, esthetic obturator prosthesis for immediate placement after a partial maxillectomy. The approach involved simultaneous reciprocation and support of the maxillary defect during the surgery and minimized the incidence of cicatricial contracture of the soft tissue, preventing permanent facial deformity and dysfunction.
