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.
Highlights
The aim of periodontal regeneration is to improve clinical outcomes of teeth considered to be compromised, namely characterized by the presence of deep pockets and loss of supporting tissues, including alveolar bone, cementum, and periodontal ligament[1]
An incision is performed at the palate to expose the bony defect, with a split-full-split coronally advanced envelope flap performed on the buccal side and a connective tissue graft (CTG), obtained from the de-epithelialization of a free gingival graft, sutured coronally at the base of the deepithelialized papillae of the teeth adjacent to the bony defect
This approach may enhance the complete resolution of deep infrabony defects and improve the buccal and interproximal soft tissue
Summary
The aim of periodontal regeneration is to improve clinical outcomes of teeth considered to be compromised, namely characterized by the presence of deep pockets and loss of supporting tissues, including alveolar bone, cementum, and periodontal ligament[1]. The connective tissue graft (CTG) was utilized as a buccal soft tissue wall for the interproximal defect and was involved in a bilaminar technique to achieve a complete coverage of the treated roots.
