Title : 3D Ridge augmentation concept
Although implant treatment has evolved since first Branemark rehabilitation the need for a bone housing is still primary task. Many times oral surgeon face huge bone defects that limit implant supported prosthesis and have to decide what kind of regenerative treatment to proceed, and can be lost among the variety of procedures that are find in literature. One of the biggest problem is how to summarize the surgical protocol with many different options, from autologous block graft to xenogenic and synthetic particles. Our purpose is to create a method to link the regenerative protocol to the amount of bone defect, in order to give predictability to treatment. The classification of the timepoint, immediate or late, lead to a maneuver that tend to maintain the ridge architecture, and have the benefit of most esthetic result, and can be classified as ridge preservation - 4 walls defect - or ridge regeneration - 3 walls defect - associated or not with the immediacy of implantation when the approach is simultaneous to tooth loss. On the other hand, after the healing period, in the late approach, the objective of treatment is to restore the ridge architecture, and aesthetic results can be achieved but with less predictability. The predictability of treatment can be guarantee when rigid protocols has been followed, and the knowledge of bone defect classification assure the right treatment to be done. This lecture will show the different aspect of horizontal bone defect, and the influence of cancelous bone between the buccal and lingual cortical and how it permits a more flexible treatment protocol, and how the lack of cancelous bone limits it. At lest, how to give predictability when treating 3d defect (vertical bone defect), and the new perspective in biomaterials that can be used.
