Background: The purpose of this trial was to assess the potential of connective tissue graft wall technique to improve the clinical and radiographic outcomes of intra-bony defects and root coverage outcomes simultaneously. Methods: Ten patients with Cairo's RT3 gingival recession associated with intrabony defects were treated with this technique. The recession defects were treated with a coronally advanced envelope flap and simplified papilla preservation at the site of the defect. A de-epithelialized free gingival graft was harvested and positioned buccal to the defect creating a buccal wall at the defect. Clinical parameters including; recession depth, probing depth and clinical attachment level were measured at baseline and 6 months. The radiographic bone gain was evaluated at 6 months. Results: At 6 months, this study reported mean±SD in recession depth reduction of 2±0.62 mm at 6 months and mean±SD absolute reduction in probing depth of 2±0.7 mm. regarding clinical attachment level, a mean±SD gain of 2±0.67 mm was achieved after 6 months. The radiographic mean±SD depth of intrabony defect showed a statistically significant reduction of 0.20±0.24 mm at 6 months (P≤0.05). Conclusion: This study suggests that the connective tissue graft wall technique might improve root coverage and regeneration of intrabony defects simultaneously.
