# Modified Technique to Fabricate a Definitive Closed Bulb Hollow Obturator for Maxillectomy in a Patient Following COVID-Associated Mucormycosis: A Case Report

## TL;DR

A new method was developed to create a lighter and more stable obturator prosthesis for a patient who had maxillectomy due to mucormycosis.

## Contribution

A novel flasking technique and modified impression method were introduced to improve prosthesis design.

## Key findings

- The flasking technique reduced the prosthesis weight, enhancing stability and retention.
- The modified impression technique effectively captured palatal deformities.
- The prosthesis provided an effective oro-nasal seal for the patient.

## 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.
