Treatment of Multiple Gingival Recessions by Tunnel Technique and Acellular Dermal Matrix Graft: A Case Report

Abstract

Abstract: Successful clinical outcomes have been achieved with various root coverage procedures for the treatmentof Miller Class I and II multiple gingival recessions. Regarding Miller Class III recessions, unpredictable success ratewas reported due to the loss of interproximal tissue support. Recently, it has been demonstrated that complete rootcoverage is possible in Miller Class III defects, when the defects present mild interdental attachment loss. This casereport describes the application of acellular dermal matrix graft (ADM) and tunnel technique (TUN) combination,for the treatment of Miller Class III multiple gingival recession defects. At 12-month, complete root coverage onteeth #41 and partial root coverage on teeth #31 with mean root coverage of 83.3% were achieved. Root coverageesthetic score was 7 with successful esthetic results. Besides significant defect coverage increase in keratinized tissueheight and gingival thickness were obtained. According to the present clinical case, Miller Class III multiple gingivalrecessions can be predictably treated with TUN+ADM, if the attachment loss is not too severe.
