Double Duplicate Technique for CAD/CAM Full-Arch Immediate Loading: A Technical Description and Case Report

Full-arch fixed implant-supported prostheses have shown high biologic success rates after long-term follow-up, along with technical and prosthetic complications. Adequate planning is necessary for immediate implant occlusal loading in a completely edentulous maxilla or mandible. For totally edentulous patients, the main prosthetic problem is the transfer of diagnostic information to the master cast when an immediate loading approach is used. The aim of this clinical case report is to illustrate a new prosthetic protocol for immediate implant loading in edentulous or potentially edentulous patients. This innovative procedure can successfully guide the clinician step by step in a predictable way from diagnosis to delivery of an immediately loaded implant-supported full-arch rehabilitation.
