Maxillary defects are created by surgical treatment of benign or malignant neoplasms, congenital malformation, trauma and recently because of post covid mucormycosis. The size and location of the defects influence the degree of impairment and difficulty in prosthetic rehabilitation. Lack of support, retention, and stability are common prosthodontic treatment problems for patients who have had a maxillectomy. A prosthesis used to close a palatal defect in a dentate or edentulous mouth is referred to as an obturator. The obturator prosthesis is used to restore masticatory function and improve speech, deglutition and cosmetics for maxillary defect patients. The weight of the maxillary obturator is a dislocating factor because the prosthesis often acts as a cantilever. The laboratory procedure generally used in the construction of a hollow obturator is rather complicated. A more simple and accurate method which facilitates the processing of an obturator will be described. this article discusses about a modified technique to fabricate a two unit oral characterized and hollow detachable definitive obturator for rehabilitation of patient undergone bilateral maxillectomy after post covid mucormycosis.
