After tooth extraction, bone resorption of varying amounts always occurs as the edentulous site of the alveolar process undergoes both qualitative and quantitative changes. Current knowledge suggests to augment fresh extraction sockets rather than to wait for spontaneous healing and perform further guided bone regeneration. This surgical approach, under the name of Alveolar Ridge Preservation, is able to compensate the marginal bone remodelling, maintaining more than 90 percent of the original ridge width. Implants inserted in preserved ridge have the same success rates of implants inserted in native bone. During the workshop, participants will learn how to select the optimal technique and manage bone substitutes, membranes, and collagen matrix.
