Porcine-derived acellular dermal collagen matrix and enamel matrix derivative for the treatment of infrabony defect in the esthetic area

Abstract

This case report describes a modified connective tissue graft wall technique with enamel matrix derivative proposed to treat vertical bony defects. The surgical procedure consisted of a coronally advanced flap with a porcine-derived acellular dermal matrix placed below, acting as a buccal soft tissue wall of the bony defect. The patient showed a bony defect between #12 and #13 with horizontal bone loss and a deep infrabony component at the mesial area of the canine. At one year after surgery, the position of the interdental papilla and the clinical attachment level gain were improved along with radiographic bone defect fill.
