Abstract: Introduction: A successful placement of an intraradicular post needs a good endodontic treatment. Consideration should also be given to the possibility of its future removal. Authors have shown that approximately 10% of cases of teeth indicated for endodontic retreatment require removal of intraradicular posts. Objective: To carry out a concise systematic review to analyze the reasons for replacing intraradicular posts, the most effective and used techniques for removing the metallic post, the manufacture of the fiberglass post, and the difference between the two types of posts. Methods: The present study followed a systematic review model, following the rules of systematic review – PRISMA. The search strategy was performed in the PubMed, Cochrane Library, Web of Science and Scopus, and Google Scholar databases. Results and Conclusion: A total of 112 articles were found. A total of 56 articles were fully evaluated and 18 were included in this study. Based on the objective and results found in the present study, the review demonstrated the main advantages and disadvantages of the clinical performance of cast metal posts and fiberglass posts, as well as the reason for switching from metal to fiberglass posts. Despite the wear caused by endodontic treatment, it is important to check the remaining dentin to choose the best retainer, observing the amount of this remaining structure, as it directly influences the selection of the post. Regarding the removal of the metallic pin, wear, ultrasound, and seizure/removal with some traction device are used. The replacement of the metallic post can opt for fiberglass posts because they have a greater advantage compared to the metallic post, mainly for aesthetics, the manufacturing technique is more agile, they do not generate risks of root fracture and if, for any eventuality, it needs to be removed. to portray the channel, the technique is smooth and easy.
