A Combined Digital Technique for Manufacturing Functional Fixed Implant Prosthesis Prototypes Using a CAD/CAM Software.

The manufacture of complete-arch fixed implant prostheses requires many technical steps to ensure a successful outcome. With the use of monolithic materials such as zirconia, the design of the prosthesis is crucial for a superior result. The aim of this article is to outline a combined technique using a CAD/CAM software for the manufacture of fixed implant prosthesis prototypes for complete-arch implant rehabilitations, which can be done in-house with minimal equipment. This makes it accessible and feasible for those who wish to be involved in the design phase of such prostheses. The method involves collecting several 3D data files including the patient's current prosthesis, the definitive cast, occlusal records and photographs. The technique is described using a patient case that has been provided with digitally designed and in-house manufactured prototypes.
