The Prosthetically Guided Regeneration (PGR) approach as a key to manage complex cases in implant dentistry: the general strategy and the rule of soft tissues

Abstract:

Despite Prosthetically Driven Implantology represents today a well consolidated concept, this is not always applied, with potential negative results of the implant supported reconstruction. The Prosthetically Driven concept can be even more difficult to apply, in presence of soft tissue/bone defects that can influence negatively the 3-D implant position and the esthetic result. The concept of Prosthtetically Guided Regeneration (PGR) has been codified to create a rational diagnostic and treatment protocol to complex implant cases presenting bone and soft tissue defects. A special wax-up including the atrophic ridge and teeth will allow to recognize and to precisely define the presence of defects and will guide the following steps of treatment. The PGR protocol will also allow to classify different degrees of atrophies, and to select the more appropriate reconstructive technique. A more accurate planning, and a better communication with the patient and between the different components of the team can represent other benefits of this approach. The first part of the presentation will describe step by step the protocol and will focus on soft tissues augmentation techniques. The second part of the presentation will present the new updated information about bone augmentation techniques based on CAD-CAM technology.

Aims & Learning Objectives:

• understand the protocol of Prosthtetically Guided Regeneration (PGR)
• classify clinical cases in different classes following this protocol
• select the best treatment strategy for each class.
• understand the benefits and limits of soft tissue augmentation
• understand the benefits and limits of CAD-CAM based bone augmentation techniques
