The purpose of this report was to present the treatment of an avulsed immature necrotic permanent central incisor using the new mineral trioxide aggregate (MM-MTA®, Micro-Mega, Besançon, France) as an orthograde root filling. In such cases, the canal remains large, with thin and fragile walls, and the apex architecture remains divergent. This case demonstrates the efficacy of MTA in this particular situation as an effective material to support regeneration of apical tissue in immature necrotic teeth. External inflammatory resorption was detected after 3 months of the endodontic treatment. At the one-year follow-up, there were no clinical symptoms with radiographic healing of periradicular tissues, new hard-tissue formation in the apical area of the affected tooth and stabilization of the resorption.
