	                <jats:title>Background:</jats:title>
	                <jats:p>The healing potential of platelet growth factors has generated interest in using Platelet-Rich Plasma (PRP) in ridge preservation procedures. A canine study was performed to determine if extraction sites treated with platelet-rich fibrin matrix (PRFM) exhibit enhanced healing compared to sites treated with non-viable materials.</jats:p>
	            </jats:sec>
	            <jats:sec>
		            <jats:title>Methods:</jats:title>
	                <jats:p>Four dog’s extraction sockets were treated individually with PRFM, PRFM and membrane, Demineralized Freeze-Dried Bone Allograft (DFDBA) and membrane, PRFM and DFDBA, and untreated control. Treatment sequencing permitted clinical and histologic evaluation of healing at 10 days, 2, 3, 6 and 12 weeks.</jats:p>
				</jats:sec>
				<jats:sec>
					<jats:title>Results:</jats:title>
	                <jats:p>Healing was more rapid in the PRFM and PRFM and membrane sites. By 3 weeks those sockets had osseous fill. Sites containing DFDBA had little new bone at 6 weeks. By 12 weeks those sockets had osseous fill but DFDBA particles were still noted in coronal areas.</jats:p>
                </jats:sec>
                <jats:sec>
	                <jats:title>Conclusions:</jats:title>
	                <jats:p>PRFM alone may be the best graft for ridge preservation procedures. Advantages: faster healing, and elimination of disadvantages involved in using barrier membranes.</jats:p>
