The DOUBLE LAYER technique for mucogingival surgery, combining the DERMA membrane and TISSEEL fibrin sealant, was first pioneered by Dr. Domenico Patarino from Busto Arsizio. Surgical treatment of gingival recessions can utilize an acellular dermal matrix DERMA as an alternative to traditional autogenous connective tissue grafts. These heterologous biomaterials act as a three-dimensional scaffold, promoting soft tissue regeneration. The technique falls within mucogingival surgery and is frequently combined with coronally advanced flaps to achieve root coverage. Among the most recent variants is the "double layer" technique, which involves using two overlapped 1 mm layers of Derma matrix stabilized with fibrin sealant (Tisseel), aiming to increase tissue thickness and improve result stability. The main advantage over autogenous connective tissue is the absence of a donor site, reducing morbidity and surgical time. Furthermore, it allows the treatment of multiple recessions in a single session, enhancing patient comfort. Dermal matrices promote integration and revascularization, contributing to a good aesthetic outcome. They are particularly indicated in patients with limited donor tissue availability or high pain sensitivity. The therapeutic choice must be based on diagnosis, gingival biotype, and patient expectations.
