Description:
After tooth extraction, bone resorption of varying amounts always occurs as the edentulous site of the alveolar process undergoes both qualitative and quantitative changes. The alveolar bone is a tooth dependent structure that develops in conjunction with eruption, and the topography is determined by the form of the teeth and their axis of eruption. In the first phase of remodeling of the extraction site, the bundle bone is resorbed due to the lack of nutritive support from the periodontal ligament, and replaced with woven bone. Consequently, the socket’s walls will be reduced in both vertical and horizontal dimensions. This resorption may lead to aesthetic and functional disadvantages that can compromise future implant placement. Current knowledge suggests to augment fresh extraction sockets rather that to wait for spontaneous healing and perform further guided bone regeneration. Different techniques have been presented in literature in order to preserve the post-extraction site, including the use of barrier membranes, tri-dimensional matrix and bone fillers. An “open-healing” approach is nowadays commonly used, combining a proper management of soft tissues with biological integration of biomaterials. Once hard tissue has been successfully augmented, an adequate soft tissue thickness becomes mandatory in order to create healthy and stable peri-implant tissues. An innovative volume-stable collagen matrix provides the opportunity to treat soft tissue defects around implants as an alternative to connective tissue graft.
