Gingival phenotype modification therapies to increase these two dimensions (GT and KT\/AG) on the buccal aspect of teeth have been widely reported, but the literature on lingual gingival augmentation is scarce. The purpose of this paper is to report the outcomes of a case treated with an envelope flap combined with a hybrid soft tissue autograft (subepithelial connective tissue graft with an epithelial collar) for phenotype modification of gingiva lingual to mandibular incisors presenting with thin gingiva (&lt;1\u2009mm) and lack of AG in tooth # 31 and 42. At 12 months follow-up, a substantial gain in KT, AG and GT along with partial root coverage was achieved.<\/jats:p>","DOI":"10.1136\/bcr-2022-252586","type":"journal-article","created":{"date-parts":[[2023,11,16]],"date-time":"2023-11-16T22:50:11Z","timestamp":1700175011000},"page":"e252586","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Use
