Mobile prosthetic replacements bring masticatory function, aesthetics and overall satisfaction to toothless and partially toothless patients, as well as the return of lost selfconfidence. The average durability of mobile prosthetic replacements is 8 years and they usually need to be replaced due to changes in anatomical structures or wear and tear of the material. Very often, fractures of dentures occur, which can be the result of patient inattention or poor planning and poor prosthesis design. When a denture breaks, one of its parts breaks or a natural tooth is lost, denture repair is indicated. Denture repair includes all procedures on damaged or unusable dentures in order to restore them to function. Fracture of the base of the denture, fracture of the clasp or tooth can be repaired. A tooth or a clasp can also be added, and when it is necessary to add a minor connector or to repair a fracture of a major connector, the procedure becomes extremely complicated and expensive, so in these cases it is better to make a new prosthesis.
