Autologous socket preservation

Introduction: The residual alveolar ridge after tooth extraction is subject to horizontal and vertical resorption. Keeping hard and soft tissue volume and periodontal health of neighboring teeth, as well is the primary goal of socket preservation, as a part of GBR procedures. Autologous bone grafts and autologous blood derivate are the golden standard in GBR and GTR procedures, because of their osteogenic characteristics.
Objective: Using of combination of autologous graft materials in post extraction socket preservation in the lower third molar region.
Materials and methods: 22 year’s male patient came with indication of surgical tooth extraction of lower left third molar. Orthopantomography is done and made decision for surgical extraction and subsequently socket preservation for keeping tooth agonist periodontal health. Surgical procedure was made with creating triangular flap extended to trigonum retromolare region. Two PRF membranes were prepared in PRF box according dr. Choukroun protocol, mixed with bone chips collected from trigonum retromolare with bone scraper (Safe scraper-Neodent). This mixture of PRF with bone chips (sticky bone) was applied in post extraction socket and sutures were made. Immediately after surgical intervention and four months post op clinical parameters of post extraction socket width and height were measured. Fur months post op CBCT 3D was performed and evaluated bone healing by measuring newly formed bone density.
Results: From collected clinical data is noted horizontal bone loss of 2 mm, and vertical bone loss of 0.5 mm. From CBCT 3D evaluation is noted 232 HU dense newly formed bone and periodontaly protected distal root of neighboring tooth.
Conclusion: Using of autologous graft materials in socket preservation procedure presents the gold standard in everyday dental practice.
