A tooth that has undergone endodontic treatment has statistically less mechanical resistance and a higher probability of facture than a tooth that conserves its pulp vitality. This is basically due to the fact that the loss of dental tissue results in a lower resistance. For this reason, the post-endodontic tooth remnant must be treated with the aim of providing protection; consequently, the indicated restorations are usually of the onlay type or crowns. Additionally, to provide a good support for these restorations, an intraradicular anchor, such as a post, is usually required. All these restorations have the aim of providing a uniform distribution of the forces acting on the tooth (33)(34).
