ABSTRACT: 

Background: Gingival  recession can lead to root hypersensitivity, root caries, and impaired aesthetic concerns. Modified coronally advanced tunnel (MCAT) technique, which possesses various benefits that can be used to support the success in the treatment of gingival recession. Acellular dermal matrix (ADM) is used in the procedure, frequently documented indicating encouraging results in the treatment of gingival recession. The following case report is to indicate an evaluation on the treatment utilizing MCAT with ADM.
Case presentation: A male of 27 year-old arrived with main complaints of aesthetic concerns and dental hypersensitivity on the upper right teeth posterior caused by Miller’s class I gingival recession. The aforementioned technique is chosen in treatment considering the rate of success to treat the defects as the impact of gingival recession.
Case management: The MCAT with ADM commenced with the fabrication of composite stops at the contact points. Later local anaesthesia (lidocaine HCl 2% with epinephrine 1:100,000) was given. Intrasulcular incision was then made and the mucoperiosteal flap was raised with tunneling knives. The tunnel was then extended over the mucogingival junction. ADM was pulled into the tunnel by means of mattress sutures. Finally the tunnel was positioned coronally to the CEJ by means of suspended sutures placed around the contact points.
Conclusion: The use of MCAT technique with ADM (Mucoderm) is able to show satisfying outcome with the improvement of root coverage in the case of Miller’s class I gingival recession.
