A modified surgical technique will be used in both groups, the flap is extended to adjacent teeth as a modification of the current subepithelial connective tissue graft technique (Langer & Langer, 1985). In the test group, an additional EMD layer will be inserted between the ADMG and the flap, and between the ADMG and the root surface by using a sterile brush. The prescribed medication will include 0.12% chlorhexidine digluconate solution to rinse twice a day for the first fifteen days, amoxicillin for seven days, starting 24 hours before surgery, and an analgesic for three days. Patients will continue to smoke as usual and will be instructed to avoid trauma and to discontinue tooth brushing at the surgical sites during fourteen days.
