Treatment of mandibular odontogenic keratocyst by decompression with a customized removable device: A case report and literature review

Abstract

Keratocystic odontogenic tumor (KCOT) is a rare, bening intraosseous tumor of odontogenic origin with a potential of aggressive and infiltrative behavior. It shows specific histopathological features, and has a high recurrence rate. In this report, we present a case of 17 year old female patient with large-sized KCOT associated with impacted third molar in the mandibular ramus region and its decompression treatment. Decompression was applied by a customized removable appliance to prevent the closing of the cyst cavity. On the 3rd and 6th months of the control radiography, it was seen that the calcification foci began to be seen and erupting the impacted teeth as a result of shrinkage of the lesion volume. After 18 months, there was a normal contrast image on the tomography and the intraoral healing was uneventfully.Keywords: Customized removable aparey, decompression treatment, keratocystic odontogenic tumor.
