Endodontic therapy is only successful in the long run if the tooth is suitably rehabilitated. Although countless studies on various types of post and core have been conducted, there is a paucity of studies on customizing post and core with digitalization to eliminate the hassle of impression-making emphasizing the need for the development of strategic techniques.
This article aims to present a novel technique that combines the advantages of pre-fabricated post, in terms of saving clinical time, yet achieving the custom fit of post and core utilizing a digital approach. Further, this study emphasizes two case reports employing the same technique of customizing post and core utilizing Cone Beam Computed Tomography.
A compact run-through for the fabrication of a Digi Post prologues with the preparation of the post space, Standard Tessellation Language (STL) file is attained by converting the Digital Imaging and Communications in Medicine (DICOM) file of a Cone Beam Computed Tomography scan, in which the post can be designed digitally. This innovative technique allows practitioners to perform post-endodontic rehabilitation with greater confidence, simplicity and precision.
