ENDODONTICALLY TREATED TEETH
Efficient restoration of endodontically preserved teeth has a significant influence on the existence of the tooth. The lasting coronal tooth construction and the esthetic necessity find the restorative material and determine that the tooth is restored straightly or protected by post with core/crown [With greater demands for heightened responsiveness of aesthetics, the tooth-coloured metal-free post-core modality has become more prevalent in reinstating pulpless teeth [Polyether Ether Ketone is a high-performance polymer that considers the latest invention of dental science and is demanded to have improved assets similar to present materials [Three-dimensional (3D) printed posts are the type of posts that uses 3D printing technologies which are advanced manufacturing technologies based on computer-aided design digital models to create personalized 3D objects automatically [Before application of post and core, a proper endodontic treatment to the tooth is necessary to ensure adequate cleaning and shaping without causing significant harms to the root canal system [Successful restoration of endodontically treated teeth should restore the tooth’s function, esthetics and structural integrity. Therefore, direct resin composite is a widely used restorative material [Therefore, PEEK has been introduced to endodontics with potential applications as endocrown, one-piece post, core, and endodontic post with the composite body [
