The aim of this study was to evaluate the short- (1 year) and longer-term (3 years) effectiveness of a surgical procedure combining coronally advanced flap (CAF) with site-specific application of connective tissue graft (CTG) in the treatment of multiple gingival recessions (MGR). A total of 60 periodontally healthy subjects with esthetic complaints due to excessive tooth length presenting multiple (at least three) Miller Class I and II gingival recession defects (≥ 1 mm) affecting adjacent teeth in the maxilla and mandible were enrolled in the study. All recessions were treated with CAF. The CTG was applied in gingival defects with a baseline keratinized tissue height (KTH) < 1 mm or with KTH between 1 and 2 mm and gingival thickness < 1 mm. Complete root coverage (CRC) was obtained in 98.5% (263 of 267 recessions) and in 94.7% (256 of 267 recessions) of the sites at the 1- and 3-year follow-up visits, respectively. No statistically significant differences were found at 1 and 3 years in terms of CRC between sites with or without CTG and between sites belonging to the maxilla or mandible. A greater increase in KTH at 3 years was demonstrated in sites treated with CTG. This was ascribed to the tendency of the mucogingival line to regain its genetically determined position and not to graft exposure. The present study demonstrated that the proposed surgical technique combining CAF with site-specific application of CTG was an effective treatment modality for the management of MGR, obtaining 93% CRC in the CAF-treated sites and 100% CRC in the sites treated with CAF + CTG at 3 years.
