Clinical long-term evaluation of acellular dermal matrix in the treatment of root recession: case report.

Several clinical studies have documented success when using an acellular dermal matrix (ADM) to treat mucogingival defects; however, information concerning its long-term stability is limited. This article presents a case involving a patient with root recession treated with an ADM. Probing depth, marginal tissue recession, and the amount of keratinized and attached tissues were evaluated for 10 years post-treatment; the results showed long-term stability during the observation period.
