Treatment of 23 sites in 12 patients resulted in average root coverage of 84%. Total coverage was achieved in 61% of sites treated. The percentage of root coverage tended to decrease with increasing depth and width of recession. The supraperiosteal envelope reduces surgical trauma to the recipient site, maintains intact papillae, and produces consistent color blending of involved tissues in single and multiple adjacent areas of recession.
