A Successful Reinforcement and Restoration of an Already Damaged Post and Core in a Teeth with an Existing Crown That Has Received Endodontic Treatment: 3 Case Reports
Abstract
Once correctly indicated, endodontic retreatment requires the preservation of dental components. Effective treatment of teeth with severe damage to the structure of the tooth relies not only on successful endodontic treatment but also on timely postendodontic tooth repair after the same endodontic. Furthermore, for teeth with intracanal posts, the evolution of endodontic procedures and materials has decreased the indication of surgical treatment. Underneath an undamaged crown is a typical clinical occurrence of broken coronal tooth structure. The tooth can be repaired with a post and core if the underlying root is in good condition, and then, the crown is refabricated. This article outlines a method for the aforementioned scenario that makes use of the current unbroken crown. The entire crown was later rescued, and a damaged post and core were also discovered in the canal. The retrieved metallic post was re-cemented in the post space then the undamaged crown was adjusted to fit it, and the opposing arch maintained occlusion. Next, a composite resin that can be dual-cured and built up was poured into the crown, molding it to fit onto the broken tooth. As we know, the core buildup material has a property of dual curing that means it can be self-cured as well as light-cured. Hence, we waited and allowed it to get set by itself chemically. Then, after we carefully removed the crown from over it, a brand-new composite resin core was discovered and adhered to the tooth structure after that we light-cured it for complete the setting process. After that, dual-cured core build-up composite resin was used to re-cement the crown to the core. Even after a year of follow-up, the method of strengthening the tooth’s core and restoring it with the current crown was shown to be effective.
