Immediate Dentoalveolar Restoration (IDR) Technique: Preservation and Regeneration of the Natural Biology The main goal of the lecture is to share experience in how to get hard and soft tissue stability using flapless surgery in fresh compromised sockets. I will discuss very challenging clinical situations and how to deal compromised sockets with and without gingival recession, cases with severe bone loss with low or no remaining bone and with how to deal with compromised sockets without the presence of papilla always managing everything in a single procedure. I will talk about the importance of using autogenous grafts harvested from the maxillary tuberosity. Learning Objectives: Understand the principles, the step-by-step technique and indications of the Immediate Dentoalveolar Restoration (IDR) concept. Management of the cortico-cancellous graft and the triple graft harvested from maxillary tuberosity. IDR and Osseodensification concept: How to improve implant primary stability in cases with low (no) remaining bone in periodontally compromised sites.
