The extraction sockets were treated either with PRGF or allowed to heal spontaneously. Postoperative healing was assessed by pain, Landry's soft tissue healing index, and inflammation index at 3, 7, and 15 days after tooth extraction. Histomorphometric bone regeneration was evaluated in biopsies harvested after 12 weeks of healing. Dimensional alveolar ridge measurements were performed at baseline and 12 weeks. Any postoperative complications and adverse effects were registered.
