Abstract

Purpose: To compare and evaluate the fracture resistance of endodontically treated Maxillary Central Incisors with three different bonded post and cores. Method: 30 endodontically treated maxillary central incisors were embedded in blocks of self cure resin and restored with Cast metal (Group1, glass fibre post and core (Group 2) and copy milled zirconia post (Group 3). After the post and core fabrication, thermocycling was carried out and loaded with the help of Universal testing machine. Results: All data were analyzed statistically using ANOVA test and Post Hoc Tukey’s test. The results showed that amongst the mean values in the three groups, highest value was the cast post and core with a value of 2337+/-456.39 N and least in the fiber post with a mean of 740 +/-142.25. This comparison is statistically significant with a p value of <0.001. Conclusion: Copy milled Zirconia and fiber post and core may prove to be good alternatives to the gold standard cast Ni-Cr post and core for endodontically treated anterior teeth.
