The restoration of endodontically treated pulpless teeth is a challenging dental procedure. Post and core is indicated in cases of extensive coronal tooth destruction where additional retention is required. The post is used to retain a core that can be used to retain definitive prosthesis. The choice between using a cast post and a prefabricated post depends on multiple factors such as canal configuration and remaining tooth structure. It has been said that if a canal requires extensive preparation, a well-adapted cast post and core will be more retentive than a prefabricated post that does not match the canal configuration. The cast post and core is fitted to the prepared root canal space and designed to resist torsional forces. However, one drawback of cast post is its tedious and time-consuming wax pattern technique. In this case report, we have used a time saving modified indirect technique for fabricating cast post and core, without the use of any reinforcement, no wax, no pattern resin but only rubber base impression material along with a novel technique of cementation, which utilizes a modified syringe with needle to facilitate even distribution of luting cement within the canal.
