Key Techniques Involved in Recovering Gingival Recessions: Literature Review

Introduction: Gingival recession can be defined as the apical dislocation of the gingival margin in relation to the amelio-cementary junction, or in relation to its original site, which provides a progressive exposure of the root surface. Its etiology is multifactorial, being more related to mechanical trauma, periodontal diseases and predisposing factors. Objective: To analyze the main techniques involved in root coverage of gingival recessions as well as to evaluate tissue response, according to different prognoses. Methodology: A bibliographic survey was conducted from 2006 to 2019 in the databases Lilacs, PubMed and Scielo. The search strategy used was “recession” and “gingival” and “gingival” and “recession” and “treatment”. Articles that did not elucidately portray root coverage methods or evaded the study objective were excluded. Results: The most frequently used techniques were “coronary repositioning flap” and “subepithelial connective tissue graft” because they had more satisfactory results. Conclusion: The literature points to the subepithelial connective tissue graft as the “gold standard”, which, being removed from the patient's own organism, expresses better results in root coverage and also shows positive results in the Acellular Dermal Matrix (MDA), as it is a Allogeneic graft taken from tissue bank donors, minimizing patient discomfort.
