The future of restorative dentistry is … digital!

Contemporary restorative dentistry is changing dramatically over the last couple of years. Especially the development of intra-oral scanning devices and the introduction of new composite and hybrid ceramic materials suitable for the fabrication of CAD/CAM restorations opened the doors towards full digital restorative dentistry.
The present case describes the integration of a full digital workflow for the restoration of an endodontically treated lower molar, of which the structural integrity was compromised due to dentine cracks, with an indirect biomimetic CAD-CAM composite restoration.
