Abstract:	When it comes to oral care, it is always advisable to evaluate and reevaluate situations in order to decide what treatment attitude needs to be adopted when facing difficult cases. When it comes to endodonticaly treated teeth where the prognostic is not very good, the question always arises: Extraction or Rehabilitation? For more than 100 years root-anchored posts have been used as support, in order to retain artificial crowns. Despite this, recent studies suggest that posts can be the cause of a weakening of the tooth resistance, therefore restorative procedures that help preserve pulp vitality and eliminate the need for posts are desirable. If endodontic therapy is unavoidable, the conservation of the remaining tooth structure is of great importance. When a post and core restoration is necessary for an artificial crown, the most indicated type is a custom cast post, since it is the most effective means of conserving tooth structure. When using this type of post the length and retention of them must not be compromised. The purpose of this study is to advocate the use of new techniques for the restoration of extensively damaged, endodonticaly treated teeth, as alternatives to the classical techniques. We have also suggested new ways of improving the post’s retention by using techniques for subminated root consolidation, adhesive cements and sandblasting the cast and prefabricated posts.
