Although prosthetically driven implantology today presents a well-consolidated concept, it is not always applied, leading to potentially negative results for the implant-supported rehabilitation. The prosthetically driven concept can be even more difficult to apply in the presence of bone defects that can negatively influence the 3D implant position. The concept of prosthetically guided regeneration (PGR) has been codified to create a rational diagnostic and treatment protocol for complex implant cases presenting with bone defects. A special wax-up including the atrophic ridge and teeth makes it possible to recognize and define the presence of defects precisely and will guide the subsequent treatment steps. The PGR protocol also allows the classification of different degrees of atrophy and the selection of the most appropriate reconstructive technique. More accurate planning as well as better communication with the patient and among the treatment team members are further benefits of this approach.
