The success rate of endodontic treatment is achived by removing or significantly reducing the number of bacteria, preventing repeated bacterial contamination, filling root canals, and highquality post-endodontic reconstruction of dental crowns. Protocol used to treat the tooth includes cleaning and enlargement of root canals, due to whichstability of the tooh itself is impaired and its mechanical and physical properties are changed. To preserve dental structure and ensure its longevity within the stomatognathic system, whichis under constant load from external forces, it is essential to carry out an adequate reconstruction of the crown of that tooth. Through thoroughly performed diagnosis, which includes obtaining the patient's anamnestic data, detailed evaluation of radiological images, and conducting intra- and extraoral examination as well as particulat tests, one approaches the creation of a therapy plan. Depending on the condition of the remaining dental tissue, periodontium, position of the tooth, and other teeth in the mouth, modern dentistry offers numerouos materials that can suppy the crown of the tooth. Moreover, the patient's wishes and possibilities are an imperative aspect that cannot be ignored. Direct and indirect restorations and prosthetic restorations are offered as post-endodontic care. One can choose from composite or glass ionomer resins, zirconia, ceramics, and others that are not common practice. Often in treated teeth, it is necessary to make the post-and-core system to increase the clinical crown of the tooth, which can be individual or ready-made. Post-endodontic reconstruction of the crown of the tooth represents a spectrum of numerous procedures and possibilities available to restore the tooth to its form, function, aesthetic properties, and, ultimately, its role in the stomatognathic system.
