Fabrication of a closed hollow bulb obturator for the rehabilitation of an acquired partial maxillectomy defect due to mucormycosis

Patient affected from post-COVID mucormycosis often require local debridement or surgical resection resulting in maxillectomy. This is frequently quite extensive or bilateral and spares very little of the hard and soft tissues in the oral cavity. Both surgery and prosthetic rehabilitation are needed to rehabilitate such extensive defects. Once the patient has grown accustomed to the temporary prosthesis and effective healing has taken place, a definitive prosthesis is inserted for the patient. Definitive obturators require careful thought during design to ensure longevity and superior retention and stability. This article documents the prosthetic rehabilitation of a partial maxillectomy defect due to mucormycosis which resulted after COVID
