title: Case report: removal of fractured endodontic posts with a sonic instrument.
abstract: Fracture of endodontic posts within the root canal system is one of the causes of failure to restore endodontically treated teeth. Various techniques, with varying degrees of success, have been proposed in the literature for the removal of fractured posts prior to re-restoring the tooth. This case report describes the use of a sonic device to dislodge and remove two fractured prefabricated metal endodontic posts from teeth UR1 and UL2. The reader is also introduced to a variety of post removal techniques available.
