Abstract
Maxillectomy defects after oncologic surgery can create a communication between the nasal and oral cavities, leading to significant challenges in mastication, swallowing, speech, and facial aesthetics. Prosthodontists play a critical role in rehabilitating such defects through obturator prostheses. This case report presents a digital workflow for fabricating a two-piece hollow bulb maxillary obturator for a patient with a large acquired maxillary defect and severe trismus. The prosthesis comprises a hollow bulb component and a denture segment, which interlock using neodymium magnets. The two-piece obturator was digitally planned and 3D-printed, resulting in a lightweight, aesthetically pleasing, and easily insertable prosthesis. This approach effectively improved the patient's quality of life, demonstrating the advantages of digital design in complex prosthodontic rehabilitation.
