[Apicoectomy and reverse filling procedure in posterior teeth].

Abstract

In this paper, we present the apicoectomy with reverse filling procedure in posterior teeth, as an alternative surgical method, in those cases where conservative endodontic treatment is unable or fails to bring successful results (prosthetic restorations, broken instruments, calcified and tortuous root canals, dens in dente, unfinished root apex). We choose to restrict our presentation in posterior teeth where the surgical procedure is more difficult due to anatomical conditions (maxillary sinus, mandibular canal, number of root canals, inaccessible posterior oral cavity, etc). We analyse the indications of such an operation and the elements we examine to evaluate the cases. We are showing the different stages of the operation as well as the usage of original instruments for the retrograde amalgam procedure. There is a further discussion on problems from the usage of the filling material, the dental amalgam, and, the problems throughout the procedure (level and degree of the apical bevel, cavity preparation, etc).
