Three case reports are presented that demonstrate the use of full-thickness flap/subepithelial connective tissue grafting for root coverage on the lingual surfaces of the mandibular anterior teeth. This is accomplished using an envelope full-thickness flap technique with intramarrow penetrations at the recipient site. Miller Class I, II, and III gingival recession defects and gingival perforation defects were treated. Complete root coverage was achieved in two Miller Class I gingival recession defects, in one Miller Class II gingival recession defect, and in two gingival perforation defects in areas that exhibited no radiographic evidence of bone loss. Partial root coverage was achieved in two Miller Class III gingival recession defects in an area that exhibited radiographic evidence of bone loss. Although the majority of the exposed root surface was covered in these two Miller Class III defects, about 1 mm of root surface remained exposed, which seemed to closely correspond to the amount of bone loss that was noted radiographically. A grafting technique has been presented that can be used to restore the functional properties of the lingual gingiva of the mandibular anterior teeth by repairing gingival defects and re-establishing the continuity and integrity of the zone of keratinized gingiva. Our clinical impression is that this has made it easier for the three patients presented in this report to maintain the lingual surfaces of the mandibular anterior teeth with routine oral hygiene measures.
