Abstract

A fully digital workflow for designing and manufacturing a splinted framework and a custom tray for the impression of multiple implants placed with guided surgery is described. This digital workflow protocol does not require extra visits after surgery to prepare for the definitive impression because of the use of preoperative digital implant planning data. As a result, it helps reduce laboratory procedures, chairside time, and treatment cost.
