Tooth extraction with socket preservation graft prior to implant placement with mandibular (retromolar area) alveolar ridge autograft

Introduction: Prior to implant placement, adequate bone must be present. Understanding the basics of bone grafting and reconstruction techniques is critical for successful implant treatment. Different bone augmentation materials have been described with autogenous bone grafts being considered the gold standard due to their osteogenic, osteoinductive and osteoconductive potential.Aim: The purpose of this paper is to present a clinical case of using a bone block taken from the mandibular retromolar region for socket augmentation after tooth extraction for the subsequent installation of an intraosseous dental implant.Materials and Methods: In order to demonstrate using a bone block of the mandibular retromolar region for socket augmentation after tooth extraction and the subsequent installation of an intraosseous dental implant, the following case is presented: patient M., 40 years old, who planned to undergo dental implantation after extraction of tooth 47 with simultaneous socket augmentation with Bio-Oss Collagen xenograft and Bio-Gide bioresorbable membrane. Results: The application of xenograft and a barrier membrane immediately after tooth extraction failed to preserve ridge dimensions. The use of a bone autoblock taken from a place adjacent to the alveolar bone defect, which remained after an unsuccessful attempt to eliminate it immediately after the extraction of tooth 47 (Bio-Oss Collagen + Bio-Gide), provided the possibility of restoring the volume and quality of bone tissue sufficient for positioning of the NobelReplace dental implant and subsequent dental prosthetics.Conclusion: The proposed bone block technique restored bone volume and quality and allowed for the placement of an intraosseous dental implant
