Endodontic treatment of pathological processes in the dental pulp reduces the resistance of the remaining tooth structure which can lead to breakage and ultimately tooth loss. Therefore, it is extremely important to apply correct postendodontic therapy to achieve a vertical stabilization of the remaining dental crowns, restoration of hard dental tissues and finally the restoration of teeth. Poor postendodontic reconstruction can lead to fracture of the remaining tooth structure and oral fluid passing under restoration, causing melting of the root canal filling. In order to prevent this, it is necessary to choose an adequate restoration. Types of restorations used for postendodontic therapy are intracanal upgrades (metal and non-metal, i.e. aesthetic), endocrown, direct and indirect restorative materials. At the present time, the use of aesthetic materials is convincingly superior to metal materials, due to aesthetic reasons and simpler preparation. Composite posts reinforced by glass fibre, with the appropriate adhesive cementation, imposed as the best choice because they show the modulus of elasticity similar to dentin, which is why the occlusal forces are evenly distributed on the tooth. This also means that possible fractures of tooth are not so severe, it is easier to remove the remains from the root canal, and consequently the possibility of saving the tooth is much higher. If the use of classical intracanal upgrade is not possible, because of complex root canal structure or a lack of space, or when restoring teeth with reduced clinical crown, endocrowns will be used. Direct and indirect restoratives are the rarest indicated types of restoration due to their inability to sufficiently harden and support tooth structure.
