Oral cancer treatment involving the maxilla and/or mandible often results in esthetic and functional deficits that can diminish the patient's quality of life. As a result, expeditious reconstruction of the defect and dental rehabilitation is desirable. Dental rehabilitation shortly after reconstruction with an osteocutaneous free flap and resection prosthesis is a persistent challenge for patients with oncologic defects where immediate dental rehabilitation is not a possibility. Additionally, conventional prosthesis fabrication techniques are impractical or impossible due to postoperative anatomical changes and limitations in clinical armamentarium. To address these limitations, a technique and a novel implant-supported prosthetic workflow for the oncologic patient were developed to provide interim dental rehabilitation for such clinical situations. This article describes the prosthesis fabrication technique, reports short-term outcomes, and evaluates patient-reported quality-of-life outcomes using the FACE-Q Head and Neck Cancer Module.

For patients with head and neck cancer requiring a maxillectomy, obturator prostheses help with quality of life. These patients routinely require adjuvant oncologic treatments with significant adverse effects. Treatment sequelae can leave patients with difficulty speaking and swallowing, reduced salivary function, reduction in maximal incisal opening, and at risk of osteoradionecrosis. A 55-year-old African-American woman presented with significant trismus and reduction in maximal incisal opening after treatment for squamous cell carcinoma of the left maxillary sinus. She had received a left total maxillectomy with adjuvant chemotherapy and radiation treatments. With her reduced opening, she was no longer able to insert her interim obturator prosthesis, which caused difficulty speaking and nasal regurgitation. A cone beam computed tomography scan was made of the patient's maxillectomy defect. From the Digital Imaging and Communications in Medicine file, a definitive cast was 3-dimensionally printed to fabricate a flexible silicone obturator prosthesis. This treatment has allowed the patient to return to a functional quality of life and could help other patients in similar situations.
