The restoration of endodontically treated tooth still remains a challenge. The success of therapy and tooth survival depend primarily on the quality of restoration. The most important factor for choosing the type of restoration should be the quantity of the remaining tooth structure. Direct restorations are more easily made, only one visit is required and they are cheaper for the patient. Indirect restorations have better physico-mechanical properties, and, in comparison to direct restorations, polymerization shrinkage of composites does not produce stress on cavity walls. In this case report, three clinical cases of restoring endodontically treated teeth are shown. In the first case, a direct composite restoration with fiber reinforced composite core is shown. The fiber reinforced composite was used to reinforce the remaining tooth structure and reduce the possibility of crown and/or root fracture, that could lead to tooth loss. In the second case, open “sandwich” technique is shown, where a combination of glass ionomer cement and composite is used. Open “sandwich” technique is used, because preparation of the cavity was under gingival margin and dry working field could not be ensured. In the third case, composite bridges in the posterior region and a restoration of the frontal teeth are shown. The composite bridges are fiber reinforced and their base is made from fiber reinforced composite to enhance their physico-mechanical properties. Development of materials and new findings about properties of endodontically treated teeth open up new possibilities for restoration of endodontically treated teeth. In the presented clinical cases, materials and techniques were used for direct and indirect restorations in order to ensure the success and longevity of the restoration as well as the survival of endodontically treated teeth.
