The recovery of teeth that have been extensively destroyed by dental caries can be achieved through direct and indirect restorative procedures. This paper presents a case of the esthetic and functional recovery of permanent maxillary incisors with extensive dental caries in an adolescent patient through the use of a composite resin and "biological posts and crowns". A case report was drafted to describe the direct restoration of central maxillary incisors using composite resin and endodontic treatment of the lateral maxillary incisors, the construction of dentinal posts, the adaptation and cementing of the posts to the root canals, preparation and molding of crown portions, model construction, the choice of extracted teeth and the making and cementing of "biological crowns". The use of a composite resin and the cementing of "biological posts and crowns" reestablish dental esthetics and function. Biological restorations maintain all the characteristics of natural teeth and have a significant psychosocial impact on the patient's quality of life. However it should be stressed that this technique was only indicated in the present case after the determination of a significant improvement in oral hygiene.
