Digital chairside workflow for CAD/CAM fibre post-and-core and provisional crown fabrication in a maxillary lateral incisor after root canal treatment.

Abstract

This report describes a fully digital chairside workflow for the metal-free reconstruction of a severely damaged maxillary lateral incisor within a single treatment session. After a root canal treatment, the post space was prepared and digitised. Subsequently, a computer-aided design/computer-aided manufacturing (CAD/CAM) chairside workflow was implemented to fabricate an individualised post-and-core using glass fibre-reinforced epoxy resin, together with a long-term provisional single crown (SC) made of polymethylmethacrylate. After adhesive luting of the post-and-core, the provisional SC was secured using an eugenol-free temporary cement.
