With increase in esthetic expectations, the treatment of gingival recessions has gained importance in last few years. The aim of this treatment is to cover root surface and gain satisfactory esthetical results. Today there are many surgical methods available for this purpose. The use of sub-epithelial connective tissue graft with coronal position flap is the gold standard in the treatment of gingival recessions. However, there are some drawbacks, such as limited donor area of sub-epithelial connective tissue graft and existence of the second operational area. In order to overcome these disadvantages, acellular dermal matrixes are used in periodontal plastic surgeries as alternatives to autogenous grafts. In single tooth Miller Class I and Class II gum recessions, the best predictable results can be obtained by sub-epithelial connective tissue grafts. In addition to this, the use of acellular dermal matrix along with coronal position flap can be evaluated as an alternative for autogenous donor area.
