Among fixed dental prostheses prosthetic crowns are those that are fabricated the most frequently. The choice of materials and manufacturing technology depends on many factors: occlusion type, presence of parafunctions, position in the dental arch and aesthetic expectations of the patient. Yet, regardless of the type of the crown used, this restoration may be subject to failure while in use. Most frequently the defects involve the veneering porcelain in varying stages of failure: from small porcelain chippings (1st stage) to significant damage to the veneering material with framework exposure (3rd stage). Failure of the framework itself or the decementation of the crown are less common. To perform intra-oral repairs of dental crowns one may choose between direct and indirect methods. The method and performed procedures depend on the material of the restoration and the extent of failure. Currently, dentists have a wide variety of materials at their disposal that aid in restoring both the function and the aesthetics of dental crowns. In many clinical cases, an intra-oral repair is an alternative method to replacement with a new prosthesis that is worth considering. An analysis of articles published between years 2000-2024 was performed using five medical databases (PubMed, Medline, Cochrane Library, Web of Science and Scopus). Articles relating to causes and types of prosthetic crown failures, repair methods and survival rates were taken into consideration. From the available literature, 51 publications were chosen initially, of which 39 were further analysed.
