A wide variety ofperiodontal plastic surgical procedures have been described to cover denuded root surfaces and to correct other mucogingival problems. Langer & Calagna described the Sub Epithelial Connective Tissue Graft (CTG) technique to augment the edentulous ridge. Although auto grafts have proven to be predictable when proper technique is used, they are not without their drawbacks. The donor tissue is usually harvested from the hard palate which necessitates an additional surgical procedure on the patient. To overcome this drawback, AcellularDermal Matrix(ADM) has been developed.
20 patients with Millers Class I and Class II gingival recession were selected for the study.Patients were randomly distributed in Group A and Group B. Group A received alloderm and Group B received sub epithelial connective tissue as graft material. Both the groups were evaluated for 6 months.
Both the groups showed significant reduction in all the parameters but group B showed more reduction in recession depth and recession width at the end of6 months.
