Éxito y fracaso de restauraciones postendodónticas individuales

Abstract

Objective: The aim of this study was to determine the success or failure of postendodontic individual restorations (IPR), with a post-crown system, carried out in the Faculty of Dentistry of the University of Cuenca in the period 2012 - 2017. Methods: It was a descriptive cross-sectional study in which a sample of 121 IPR with post-crown was examined. A clinical analysis was performed to verify faults in the selected restorations. In cases of suspected post-crown system fracture, a radiographic analysis was made in order to corroborate the clinical evidence. Results: 87.6% of successful IPRs were evidenced. The most frequent cause of clinical failure was the de-coronation. The coronal ceramic restorations presented a success of 96.8%; while the IPR that had as a coronal restoration material to the acrylic, presented a 100% failure. Conclusions: With the present study it was possible to demonstrate a high percentage of success in the IPR performed in the Faculty of Dentistry of the University of Cuenca. The success was superior in: restorations located in posterior pieces and also in the pieces that used intra root cast metal posts; there is no difference in the percentage of success and failure between the different coronal restoration materials, except in IPR with acrylic crowns that showed total failure. The most frequent cause of failure was crown descementation
