Rehabilitation of maxillectomy defect by using closed hollow bulb obturator with a detachable lid-a case report

Abstract

A male patient aged 41-year-old presented with a fracture of the obturator and malodor. The patient gave a history of a right partial maxillectomy, followed by prosthetic rehabilitation with an obturator 4 years ago. Preliminary impressions were made and the custom tray was fabricated. Final impressions were made using monophase material. On the master cast, metal reinforced was planned using wax pattern and casted. Two separate flasks were used one for obturator and another one for lid fabrication. In the open hollow bulb portion of the obturator, female portion of the button was fixed to have the connection with the male part of the button which was fixed on the inner side of the lid. 2mm of the lid was extended into the hollow part to have the tight seal. This article describes rehabilitation of maxillofacial defect by using hollow bulb obturator with detachable lid and metal reinforced which facilitates ease of cleaning, prevention of infections by minimizing formation of biofilms, malodour and prevent repeated fracture of the obturator respectively.
