Complete digital workflow in prosthesis prototype fabrication for complete-arch implant rehabilitation: A technique.

During complete-arch digital implant scanning, one of the most technique-sensitive steps is the data registration and superimposition or matching of different surface geometry data sets because of the absence of fixed landmarks. This article describes a straightforward technique for facilitating the accurate superimposition or matching of surface scan files from digital scans for the fabrication of the prosthesis prototype with a complete digital workflow.
