Connective Tissue Graft Wall Technique and Enamel Matrix Derivative for the Treatment of Infrabony Defects: Case Reports.

The present case report describes a modification of the connective tissue graft wall technique with enamel matrix derivative applied to treat deep vertical bony defects. The technique presented uses a palatal incision to gain access to the bony defect. Deep infrabony defects affecting two maxillary central incisors associated with interdental and buccal gingival recession were treated. At 1 year after surgery, 9 and 6 mm of interdental clinical attachment level gain were seen in cases 1 and 2, respectively. The position of the interdental papilla was improved, and complete root coverage was achieved. Radiographs demonstrated bone fill of the infrabony components of the defects. This report encourages the possibility to improve, in one surgical session, regenerative and esthetic parameters in the treatment of deep infrabony defects.
