Reconstruction of endodontically treated teeth after excessive loss of tooth structure: Two case reports

The prognosis of endodontically treated teeth depends not only on the success of the endodontic treatment, but also on the type of reconstruction. The use of fiber-reinforced resin (FRR) posts to restore endodontically treated teeth has gained popularity due to its mechanical and esthetic characteristics as well as properties of modern adhesive systems. The aim of this article was to show a clinical technique to reconstruct endodontically treated teeth with great loss of tooth structure using direct fiber-reinforced post systems and direct composite restorations. The first case was a patient with the fractured right second lower premolar. The tooth was endodontically treated and reconstructed thereafter. After the preparation of the root canal and cementation of a FRR post, particular attention was paid to the incremental and curing techniques adopted to reconstruct coronal part of the tooth. The second case was a patient with the fractured first right lower incisor. This tooth was treated in the same way. Direct composite reconstruction of endodontically treated teeth is an alternative to the prosthodontic therapy and can postpone prosthodontic therapy for a long time
