The Reverse Scan Body Protocol: Completing the Digital Workflow.

Recently developed extraoral techniques have allowed for an alternative approach for the digital acquisition of implant positions in fully edentulous patients. The "reverse scan body protocol" digitally simulates the traditional back-pouring technique long utilized in analog workflows. This article presents two cases in which an extraoral scanning technique was used to capture implant positions, design a prototype, and fabricate the definitive monolithic zirconia full-arch prosthesis.
