[Strategies for posterior teeth reconstruction after endodontic treatment: a case report].

Reconstruction of hard dental tissue after endodontic treatment is a difficult and important duty of the dentist. According to the general opinion, endodontically treated teeth are inferior in quality, more brittle, predisposed to fractures and cracking. Logically, such teeth require reconstruction to prevent fractures, cracks, and bacterial microleakage leading to reinfection. The procedure of choice in the nineties of the 20th century was restoration with a metal post and prosthetic crown. Advances in materials resulting in improved adhesion to hard dental tissue have prompted a change in the reconstruction strategy for posterior teeth after endodontic treatment. In the case of molars, the crown can be restored with composite materials thanks to additional retention offered by the chamber of these teeth. The recommendation for premolars is to reinforce them with a glass fiber post. We now present a case which illustrates the actual trends in reconstruction of posterior teeth after endodontic treatment.
