Abstract:
The resistance to fracture of endodontically-treated maxillary central incisors restored using the custom-milled zirconia, post group, versus the prefabricated fiber post group is of interest. Hence, sixty teeth were separated into two groups and restored similarly and undergo static loading. Fracture resistance of zirconia post was significantly greater (809 45 19 NY 8219 on average) than fiber post (567 26 19 NY 821). The main outcomes in the case of zirconia posts were the non-resettable failures (83 per cent), but in fiber posts more of the outcomes were resettable (73 per cent). Thus, post selection shows trade-off with mechanical strength and ability to repair.
