The article describes the prosthetic treatment of a patient after multiple removal of chondrosarcoma and its recurrences. The patient experienced an oronasal fistula, which made her everyday life difficult. A decision was made to prepare a long-term obturator to close the current oro-nasal communication. In dental prosthetics, obturators are used to restore missing soft and hard tissues in the jaw bones. Considering the time of application, obturators are divided into: immediate, early and final. Immediate obturators are made before the operation that would lead to the oro-nasal communication, and early obturators are made when the prosthodontist was unable to take an impression/scan before the resection operation. Obturators are made of hard, flexible or hard materials covered with soft material. They can have precision elements attached to be supported on the patients natural abutments or anchored on dental implants.1-5 The case described below presents the procedure for making a long-term obturator made of acrylic material, supported by one-year follow-up of the patient.
