Rehabilitation of a Post-Mucormycosis Maxillary Defect Using Interim and Definitive Hollow Bulb Obturators: A Case Report

The defects in the maxillary region secondary to mucormycosis present significant functional and esthetic challenges, requiring a staged prosthodontic approach for optimal rehabilitation. Obturators remain the standard treatment option when surgical reconstruction is not feasible or deferred.

A 43-year-old male with a history of right-sided maxillectomy for mucormycosis presented with oronasal communication, impaired mastication, hyper nasal speech, and aesthetic concerns. After initial healing with a surgical obturator, an interim hollow bulb obturator was fabricated to restore function during the healing phase. Subsequently, a definitive cobalt–chromium hollow bulb obturator with a metal framework was designed for long-term use. Both prostheses were fabricated following meticulous clinical and laboratory steps to ensure optimal retention, stability, and patient comfort.

Rehabilitation with interim and definitive obturators in a sequential manner effectively restored function, speech, and esthetics in a post-mucormycosis maxillary defect. A well-planned treatment approach improved patient adaptation and quality of life.
