Clinical Outcomes of Enamel Matrix Derivative and Connective Tissue Graft in Modified Coronally Advanced Tunnel (MCAT)

The modified coronally advanced tunnel (MCAT) technique is performed to prepare a recipient site. A subepithelial connective tissue graft (SCTG), harvested from the palate, is inserted into the tunnel using guiding sutures and stabilized. The flap is advanced coronally to completely cover the graft and achieve primary closure.

This intervention involves the application of enamel matrix derivative (EMD; Emdogain, 0.15 ml gel form) in conjunction with the modified coronally advanced tunnel (MCAT) technique. Following tunnel preparation, EMD is applied to the exposed root surface to enhance periodontal tissue regeneration.
