Resorbable membrane in the treatment of human buccal recession: a nine-case report

Recent studies have reported the successful use of guided tissue regeneration procedures with nonresorbable barrier membranes to treat buccal recession in humans. Nonresorbable membranes, however, require a reentry procedure for removal, disturbing the delicate healing process. Resorbable membranes were used in a guided tissue regeneration procedure in nine patients with one site of buccal recession each. The resorbable barrier yielded satisfactory clinical results, providing significant gains in probing attachment and root coverage. However, both the surgical technique and the design of the barrier used require improvement for application at sites of buccal recession.
