Two patients having Miller's Class I or Class II recession defects participated in the study. One was treated with a collagen membrane covered by a coronally positioned flap. Second patient also had bone graft placed beneath the membrane. Clinical parameters were recorded. Patients were followed postoperatively and healing was evaluated at 1, 3 and 6 months, with recession depth as the primary criteria for assessment. This case report revealed a favorable tissue response to bone graft and collagen membrane from both clinical and esthetic point of view in the treatment of gingival recession. Root coverage tended to be better with the addition of bone graft. Bonegraft, Collagen membrane, Coronally advanced flap, Gingival recession, Guided tissue regeneration. INTRODUCTION In current practice of Periodontics, clinicians are faced with the challenge of not only addressing biological and functional problems present in the periodontium, but also providing therapy that results in acceptable aesthetics. The presence of gingival recession around anterior teeth exemplifies a situation in which a treatment modality that addresses both biological and aesthetic demands is required from the therapist. Gingival recession has been defined as the term used to characterize the apical shift of the marginal gingiva from its normal position on the crown of the tooth to levels on the root surface beyond the cemento-enamel junction (CEJ). (1979) introduced the term marginal tissue recession. They suggested that marginal tissue recession was a more accurate term than gingival recession because the marginal tissue may 1 2 Maynard and Wilson originally have been alveolar mucosa rather than gingiva. The ultimate goal of periodontal therapy includes not only the arrest of progressive periodontal disease but also the restitution of those parts of the supporting apparatus which have been destroyed by the disease. Gingival recession defects may be treated by a number of procedures including rotational and advanced gingival flaps, free gingival or connective tissue grafts, and by applying principles of guided tissue regeneration (GTR). The coronally advanced flap is the surgical technique of first choice when there is adequate keratinized tissue apical to the recession defect. Optimum root coverage results, good colour blending of the treated area with respect to adjacent soft tissues and complete recovery of the original (pre-surgical) soft tissue marginal morphology can be predictably accomplished by means of this surgical approach. 2 3 4 5 179
