This case report details the prosthetic rehabilitation of a patient who underwent total maxillectomy due to Wegener’s granulomatosis. Since implant treatment was not a viable option, a two-piece obturator prosthesis was designed to restore speech, mastication, and aesthetics. The prosthesis consisted of a hollow bulb component made from a silicone-based soft liner, providing retention by fitting between the nasal septum and concha, and a second acrylic resin component containing prosthetic teeth, which securely fit into the first piece.The fabrication process included impression taking, construction of the antral and oral sections, and occlusal adjustments.The final obturator successfully restored oral function and improved the patient’s quality of life. The discussion highlights key aspects of maxillectomy rehabilitation, emphasizing the importance of anatomical undercuts, weight reduction in prostheses, and alternative retention methods when implant placement is not feasible. This approach offers a practical and cost-effective solution for managing extensive maxillary defects.}, number={2}, publisher={Hacettepe University}
