A BSTRACT Mucormycosis, a rare fungal infection seen in diabetes, is now very frequent owing to the deadly triad of COVID-19 infection, diabetes, and rampant use of corticosteroids. Early diagnosis and treatment can reduce the mortality and morbidity of this lethal fungal infection. Treatment principles may include antifungal agents along with surgical debridement or resection. The surgically removed palate can have a devastating effect on the appearance and speech of the patient. Obturators allow patients to eat and drink without any suspicion of food entering the oroantral cavities/pharynx during mastication. This case series presented the prosthodontic rehabilitation of nine post-COVID rhinocerebral mucormycosis-infected patients with complete or partial defects.

Maxillectomy is the surgical removal or resection of the maxilla or upper jaw bone. Maxillectomy may be total or partial. It is performed during surgical treatment of cancer and infections (bacterial. fungal) of the oral cavity, nasal cavity and maxillary sinuses. Patient affected from post-Covid mucormycosis require local debridement or surgical resection resulting in maxillectomy. After surgery, patient has difficulty in mastication, speech, and swallowing because of communication between oral and nasal cavity. This may also give rise to psychological challenges and social exclusion. The prosthodontic rehabilitation of such patient using obturator provide a separation between oral and nasal cavity and improve the quality of life of the patient. There are various techniques and materials used for fabrication of definitive obturator. This article discusses the prosthodontic rehabilitation after maxillectomy in post-covid mucormycosis patients using obturator by conventional and 3D printed techniques.

The rehabilitation of facial deformities is a challenging endeavour that necessitates customising the procedure for each patient. Significant physical and psychological impacts might arise as a result of the deformity in the orofacial region. Post-COVID rhino-orbital mucormycosis has led to rise in extraoral and intraoral defects since 2020. To avoid further surgery, an economical maxillofacial prosthesis is an excellent choice as it is aesthetic, durable, long-lasting and retentive. This case report describes the prosthetic rehabilitation of the patient with post-COVID mucormycosis maxillectomy and orbital exenteration using a magnet-retained closed bulb hollow acrylic obturator and room-temperature vulcanising silicone orbital prosthesis. To enhance retention, a spectacle and medical-grade adhesive were also used.
