Adjacent gingival recession treated with expanded polytetrafluoroethylene membranes: A report of two cases
Two cases are reported illustrating treatment for adjacent facial gingival recession using guided tissue regeneration (GTR) with expanded polytetrafluoroethylene membranes. The clinical results showed that GTR obtained soft tissue coverage of the root surfaces and was effective in reducing hypersensitivity and improving the esthetics. In both cases, satisfying clinical results have been maintained for 6 to 12 months after reentry procedures. [P.W.]
