Evaluation of the Clinical Efficacy of De-Epithelialized Free Gingival Graft in the Treatment of Gingival Recessions

Microsurgical periodontal instruments were used during surgical procedures. In this study, specially developed tunnel instruments (Helmunt Zepf, Seitingen-Oberflacht, Germany) were used to mobilize the gingivo-papillary unit and prepare the supraperiosteal tunnel bed. After passing the coronal edge of the alveolar bone with the tunnel instrument placed in the soft tissue, it was advanced towards the apical mucogingival junction with small, circular movements. This procedure was repeated by entering from the sulcus of each tooth. Care was taken to ensure that the prepared flaps were in the same layer and opened towards each other. In the interdental areas, the papillary complex was carefully separated from the periosteum and mobilized in the buccal direction. Thus, mobilization of the entire buccal soft tissue complex was achieved in the coronal direction. After these procedures, it was checked whether the flap covered the recession areas without tension.
