Abstract
Introduction
The success of nonsurgical endodontic retreatment relies heavily on the removal of intraradicular posts, which are often placed in teeth with extensive crown damage. These posts can obstruct access to the root canal system, complicating thorough cleaning and disinfection. This article presents two clinical cases demonstrating the removal of metal posts and subsequent retreatment.
Observation
In the first case, a threaded metal post in tooth 34 fractured during removal using Stiglitz forceps. Ultrasonic tips applied in a counterclockwise motion successfully dislodged the fragment, allowing for complete retreatment and obturation. In the second case, tooth 13 was treated, and the metal post was successfully removed using forceps without complications. Both cases involved thorough root canal cleaning with RCS retreatment files, followed by irrigation with Sodium Hypochlorite, EDTA, and Chlorhexidine, and obturation using bioceramic or resin-based sealers.
Discussion
The successful removal of intraradicular posts depends on operator expertise, understanding of root canal anatomy, and appropriate tool selection. Optical aids and ultrasonic devices play a critical role in overcoming challenges. Proper technique minimizes risks such as root fractures and ensures effective retreatment. These cases highlight the importance of a patient-centered approach and meticulous execution in achieving optimal outcomes.
