Experimental Study on the Acellular Dermal Matrix Graft for the Root Coverage in Dog

Mucogingival surgery is a plastic surgical procedure designed to correct defects in the morphology, position, and dimensions of the gingiva surrounding the teeth. Many surgical techniques have been reported in mucogingival surgery. Since these procedures also include the soft tissue esthetic approach, the term “periodontal plastic surgery” has been proposed to be more appropriate. 1 Root coverage is a procedure that falls with this definition, and it has attracted more interest than others. Root coverage has been performed through many surgical techniques. The autogenous masticatory graft(free gingival autograft) was proposed by Miller as the first predictable technique to obtain root coverage. However, the procedure didn't show ideal esthetic results and offered a low degree of predictability in the correction of gingival recessions. Pedicle grafts have been reported to offer good results in terms of root coverage.1)Pedicle grafts provide the most esthetic result when adequate amount of keratinized gingiva exists. However, adequate gingiva does not always exist in adjacent locations. The guided tissue regeneration and the bilaminar techniques (BTs) consisting of connective tissue grafts with a pedicle graft have also been proposed as a possible therapeutic alternative in the management of gingival recessions. Comparative studies have demonstrated that bilaminar techniques show a significantly greater degree of predictability when the aim of the clinical trials is to obtain complete root coverage. 9,10 The rationale of bilaminar techniques is to enhance the degree of predictability of therapeutic result
