Abstract The computer-aided design and computer-assisted manufacturing of a 2-piece definitive palatal obturator 3D printed from polyetherketoneketone and 2 acrylic resins with a fully digital workflow are presented for a patient who was diagnosed with adenoid cystic carcinoma and who developed severely limited mouth opening after surgery and radiotherapy. The 18-month follow-up period revealed satisfactory function, tissue compatibility, retention, and esthetics for this patient with a maxillectomy and severe trismus.
