Root coverage stability with acellular dermal matrix in multiple gingival recessions in esthetic zone: A clinical case report with 12-year follow-up.

The importance of surgical intervention for the maintenance of long-term results by root coverage of multiple gingival recessions in an esthetic area treated with a tissue substitute (acellular dermal matrix [ADM]-Alloderm) is widely required. The present case report highlights the effectiveness of the ADM for the treatment of multiple recession defects in a female patient with Class I and II gingival recession in relation to maxillary anterior associated with esthetics and dentin hypersensitivity demands. The root coverage rate for the anterior area showed greater value with 70% of coverage; at 90 days and 2 and 12 years of follow-up, it showed 70.
