Introduction: Residual alveolar ridge bone resorption is more prominent in the horizontal, than the vertical direction. It is time-dependent, and most prominent in the first six months and the first year after tooth extraction. Several graft materials are used for keeping residual alveolar bone volume, like autografts, allografts, xenografts, alloplastic materials, etc. A-PRF as an autologous blood derivative, has been increasingly used in recent years because of its properties in angiogenesis, epithelialization and hemostasis. Simple production, low cost and non-use of anticoagulants are advantages for more mass use of it.
Aim: The aim was to investigate the impact of PRF as an adjuvant on bone quantity and quality in socket preservation.
Materials and Methods: Socket preservation with a combination of A-PRF with xenograft (sticky bone) was performed, and clinical parameters, bone density and histomorphometry were evaluated.
Results: Clinical measurements showed 1 mm horizontal and no vertical resorption four months after socket preservation, higher density of newly formed bone than bone density of periapical region and great bone quality based on histomorphometric analysis.

 Key words: A-PRF, xenograft, sticky bone, bone density, histomorphometry
