{Abstract}: Immunocompromised people developed mucormycosis as a result of the COVID-19 outbreak. Antifungal medications, surgical excision of infected tissues, and therapy of underlying metabolic problems are available forms of treatment. Usually, surgery entails completely excising the affected area. The patient is at risk for nasal twang, nasal cavity leaks, and impaired masticatory function because of these anomalies. The obturator prosthesis may form an oro-nasal seal in such problems. Additionally, lowering the prosthesis weight contributes to improved stability and retention. This case report explains a novel flasking technique to lessen the prosthesis weight and a modified impression technique to capture the palatal deformity.
