A Novel Method for Evaluating i-PRF Usage in Vestibular Socket Therapy for Immediate Implant in Defective Fresh Extraction Site

The ultimate objective of implant treatment is providing long-lasting, healthy hard and soft tissue architecture while minimizing intraoperative surgical trauma and postoperative complications. Reducing treatment duration and providing a predictable esthetic outcome are fundamental. Immediate implant placement in fresh extraction sockets is an appealing treatment option satisfying many of these requirements. However, a major concern with immediate implant placement is the possible resorption of the facial bone plate as indicated in multiple studies. This, in turn, results in loss of proper soft tissue support, thus compromising the final esthetic outcome of the implant- supported restoration. Furthermore, post extraction bone resorption would be compounded by the presence of a thin or preexisting facial bone defect and/or a thin gingival phenotype. Multiple approaches were suggested to prevent facial bone resorption and optimize the final esthetic outcome after immediate implant placement in sockets with intact facial bone and soft tissue. These approaches include simple ones like applying a graft in the gap between the implant and the facial socket wall and more sophisticated approaches such as the socket shield technique . The presence of bone and/or soft tissue defects after tooth extraction is not an uncommon finding, further complicating immediate implant placement. Several classifications for fresh extraction sockets were proposed to facilitate the selection of optimum treatment for individual cases.

Currently, a serious of studies has shown that iPRF can produce significantly greater concentrations of platelets and leukocytes when compared to the L-PRF and A-PRF.
