Abstract

This case report presents the fabrication of a maxillary obturator for a 55-year-old male patient with an upper left maxillary defect following partial maxillectomy due to osteosarcoma. The patient experienced difficulties with speech, mastication, and mouth opening due to the Aramany Class II defect. Intraoral scanning was utilized to capture the oral structures, leading to the creation of a precise 3D model for prosthesis fabrication. Acrylic resin was reinforced with silver nanoparticles to enhance strength and provide antibacterial properties. The final obturator was fabricated, polished, and adjusted to ensure optimal fit, function, and comfort. The patient was educated on oral hygiene and maintenance of the obturator. Regular follow-ups were scheduled to monitor the prosthesis's performance. This case emphasizes the benefits of combining digital technology and nanomaterials in prosthodontic rehabilitation for patients with maxillary defects.
