Alveolar ridge preservation following extraction of multiple anterior teeth with and without adjunctive enamel matrix derivative: A case report

The objective of this study was to evaluate the dynamics of bone dimensional change in extraction sockets with alveolar ridge preservation (ARP) procedure with or without enamel matrix derivatives (EMD). ARP was performed in two patients after extraction of maxillary central incisors and lateral incisors. Deproteinized bovine bone mineral with 10% collagen covered by two layers of a native bilayer collagen membrane with adjunctive use of EMD (patient 1) and without EMD (patient 2). Radiological and clinical findings: adjunctive use of EMD in ARP showed similar horizontal and vertical bone dimensional changes and soft tissue healing outcomes (spontaneous bleeding, persistent swelling, and ulceration) but the duration of postoperative pain and swelling was reduced.
