Extended Platelet‐Rich Fibrin as a Membrane for Lateral Window Sinus Lifts: A Case Series

Utilizing extended-PRF membranes in place of collagen membranes for coverage of the lateral window during sinus floor elevation was shown to be a successful treatment modality in this case series. These findings provide new opportunities utilizing denatured albumin membranes in implant dentistry and paves the way for additional applications. The material is 100% autologous, low cost. This is the first case series study highlighting its novel use for coverage of the lateral window during sinus grafting. Larger longitudinal studies are now needed with comparison to standard resorbable membranes as well as long-term follow-up of implants placed into sites grafted with e-PRF membranes.
