Removal of Metal Posts in Retreatment of Teeth With Failed Endodontic Treatment (Clinical Cases)

The removal of different materials from the root canal - gutta percha, broken endodontic instruments, silver points is the key to a successful retreatment with failed primary endodontic treatment. It is often required to remove metal posts placed in the root canals in teeth with great destruction of the clinical crown. Their removal is particular importance for accessing endodontic space, cleaning and disinfection of the root-canal system. Clinical cases The purpose of this report is to present techniques and armamentarium for removing metal posts placed in the root canal in teeth with greatly destroyed clinical crowns and the need for endodontic retreatment. The treatment of three clinical cases (in the area of 25, 36 and 32 teeth) is presented in this report. Conclusions The removal of root canal posts provides access to the endodontic space for torough cleaning and disinfection. The posts removal carries the risk of complications associated with the formation of ledges, perforations and tooth root fractures. For the safe removal of the metal posts it is required to know the appropriate armamentarium and techniques.
