Combination of Platelet-Rich Fibrin and Calcium Sulfate in Socket Augmentation

Calcium sulfate (CS), an alloplastic material, is widely accepted as a socket grafting material and undergoes rapid and complete resorption. Studies have shown that CS creates an osteoconductive lattice that stimulates bone ingrowth into a defect. PRF poses multiple growth factors, anti-inflammatory cytokines and adhesion molecules. It is biologically active up to one week. The combination of these 2 materials will serve as good grafting material for tooth socket, in order to preserve vertical and horizontal dimensions.
