Abstract :
Maxillary defects are among the most debilitating intraoral deformities, leading to impaired mastication, deglutition, hypernasal speech, and facial disfigurement. These defects may arise congenitally or, more commonly, as a consequence of surgical resections for neoplasms or infections. In recent years, post-COVID rhinocerebral mucormycosis has emerged as a major etiological factor, particularly in immunocompromised patients and those exposed to corticosteroids or prolonged oxygen therapy. Surgical management of mucormycosis often necessitates maxillectomy, creating extensive oro-nasal communications that severely compromise quality of life. Prosthodontic rehabilitation with an obturator prosthesis plays a pivotal role in restoring oral function, esthetics, and psychological well-being.This clinical case report described the rehabilitation of a 62-year-old male patient with an acquired maxillary defect following inferior maxillectomy for post-COVID mucormycosis and highlighted the importance of timely prosthodontic rehabilitation in patients with post-mucormycosis maxillary defects. The integration of digital workflows with traditional principles offers superior outcomes, ensuring functional recovery, esthetic restoration, and psychosocial reintegration in affected individuals.
