Computer-assisted tooth preparation template and predesigned restoration: a digital workflow

This article introduces a new, fully digital workflow for the preparation of a guiding template and the procedure of the clinical operation in which it is put to use. A step-by-step technique is described including the virtual CAD of the preparation, the design of the template, the restoration based on the contours of the virtual preparation, the tooth preparation guided by the template, and the bonding of the predesigned restoration. The design and manufacture of all the templates and restorations are completed before the clinical operation.
