Fabrication of a definitive obturator for a patient with partial maxillectomy defect following post-covid mucormycosis: A case report

Mucormycosis was a rapidly progressing and life-threatening fungal infection. After surgery, we should anticipate seeing more individuals with orofacial abnormalities given the total number of cases and the orofacial region's primary involvement in the previous COVID-19 pandemic. Thus, in order to improve the quality of life for individuals suffering from mucormycosis, maxillofacial prosthetic rehabilitation is of paramount importance. Postoperative maxillary defects can be rehabilitated through surgical and prosthetic procedures. An obturator was utilized as a part of prosthetic management to facilitate efficient deglutition and articulation. It also provides support for the facial soft tissue to restore the midfacial contour in cases of palatal defects. This case report describes about the fabrication of a definitive palatal obturator for a patient with postsurgical maxillary defect wearing interim obturator made of polymethyl methacrylate (PMMA). Food impaction and irritation of the fitting surface over the tissue defect, resulting in erythema to the tissue surface and discomfort of using interim obturator. With the remaining teeth and tissues serving as support, the definitive obturator made of cobalt and chromium was made. With no degradation in the prosthesis, the follow-up showed satisfactory outcomes.
