Platelet-rich fibrin matrix (PRFM) is an autologous biologic material created by centrifugation of blood. This study quantified ridge changes associated with the healing of 21 extraction sites using PRFM alone as a graft. Standardized measurements of ridge width and height were recorded at extraction, after graft placement, and after 4 months of healing. Mean width resorption 3 and 5 mm apical to the crest was 0.32 mm (4.71% loss) and 0.57 mm (7.38% loss), respectively. Mean height resorption was 0.67 mm (7.13% loss). Sites grafted with PRFM alone displayed rapid clinical healing, minimal flap reopening, and excellent bone density. Advantages of PRFM alone include less surgical time, elimination of techniques and potential healing difficulties associated with membranes, and less resorption during healing, as compared to guided bone regeneration procedures.
