Metal-ceramic prosthetic structures are still eagerly used in the rehabilitation of the masticatory system. Their common utilization by patients makes damage to the veneering ceramics a common clinical situation. The damage mainly concerns the anterior section, where the defect of the porcelain, and in particular the exposure of the metal framework, often becomes visible. Often, such restorations are replaced, although the repaired ones could serve for a long time. The repair can be carried out directly in the patient’s mouth, most often with a composite material. The procedure itself is relatively simple and the effect achieved is usually satisfactory and lasting. Properly performed repair procedure aims at establishing a strong bond, which enables further use of the restoration. The aim of this review is to present the possibilities of repairing metal-ceramic restorations and to present the mechanical and chemical methods of preparation of damaged surfaces based on selected literature. The greatest challenge in the repair of metal- -ceramic restorations seems to be obtaining the appropriate adhesive strength, which enables long-term stability effect. The strength of adhesion required to maintain a filling depends on many factors and varies over time. The combination of mechanical and chemical surface modification methods, combined with the selection of the appropriate restorative material and the correct working technique, should result in long- -term clinical success.
