Most involve relieving incisions, which cause scar tissue formation or use a tunneled approach. This report introduces a modified technique for treating a single deep recession beyond the mucogingival margin. The approach uses a laterally closed coronally advanced flap (LCAF) without relieving incisions, combined with a subepithelial connective tissue graft and enamel matrix derivative.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A 28\u2010year\u2010old woman was referred to our periodontal practice for the treatment of a progressive deep Cairo Class I recession with hypersensitivity and limited access to hygiene measures.

Especially in deep recessions, the common surgical techniques have shortcomings due to a post\u2010surgical lack of keratinized gingiva or visible scar tissue formation. This case study shows the treatment of a 28\u2010year\u2010old woman\u00b4s deep recession on a mandibular front tooth introducing a modified surgical technique for covering deep gum recessions exceeding the area of the keratinized gingiva (so\u2010called deep Cairo RT1 recessions). This new technique uses a \u201claterally closed coronally advanced flap\u201d (LCAF), which combines a curtain\u2010similar lateral closing of the flap pedicles with a coronal advancement to cover the recession without making cuts that can lead to scars. It is combined with a tissue graft from the patient's palate and a special protein to regenerate the periodontium. Six months after surgery, complete root coverage was achieved without remaining hypersensitivity and with restored access for oral hygiene measures. Minimal visible scar tissue formed. This case study demonstrates that the LCAF is a feasible technique for covering single deep gum recessions exceeding the keratinized area of the gingiva.<\/jats:p>\n
