Bilateral creeping attachment using free mucosal grafts. A case report with 4-year follow-up.

Two extensive periodontal recessive lesions in bilateral maxillary cuspid ares were treated surgically with free autogenous masticatory mucosal grafts. No attempt was made initially to achieve total root surface coverage. Evaluation of the sites during a 4-year postoperative period demonstrated unusual degrees of "creeping attachment." The maxillary left cuspid graft completely covered the root with 9 mm of gingival-equivalent tissue while the maxillary right cuspid area displayed 90% (7 mm) root surface coverage.
