Purpose: To evaluate survival rates of adhesive post-endodontic buildups made using composite resin and prefabricated quartz fiber posts. Materials and Methods: This retrospective study included all buildups placed between January 1, 2008, and December 31, 2012, by a single skilled operator using a single-adhesive system and dual-curing cement. Final restorations included direct composites, various types of crowns, and fixed partial dentures. During recall, teeth were inspected by four different dentists, and survival analysis was performed using Kaplan-Meier test. Results: A total of 301 root canal-treated incisors and canines were restored. At repeat follow-up appointments, 291 restorations were still in function after a mean time of service of 7.13 ± 2.11 years. Cumulative survival probability at 9 years was 96.0%. No parameter observed was found by log-rank test to have a statistically significant effect on survival rate. Conclusion: Adhesive buildup with prefabricated fiber posts in anterior teeth is a reliable method of post-endodontic treatment in this given clinical protocol.
