Esthetic Reconstruction of Soft Tissue Dehiscence with Subepithelial Connective Tissue Graft: A Case Report

Soft-tissue dehiscence in the esthetic zone presents significant clinical challenges, including root exposure, dentinal hypersensitivity, and compromised appearance. Subepithelial connective tissue grafting (SCTG) is considered the gold standard for soft-tissue augmentation due to its predictable root coverage and ability to enhance gingival thickness. This case report describes the management of a localized gingival recession defect in a 24-year-old male patient with a 2 mm buccal recession in relation to tooth 24, associated with a thin gingival phenotype, reduced keratinized tissue, and increased probing depth. Following initial periodontal therapy, a coronally advanced flap (CAF) combined with SCTG was performed using a trap-door technique for graft harvesting. Healing was uneventful, with progressive improvement in gingival thickness and marginal tissue position. At six months, stable root coverage and satisfactory esthetic integration were achieved. This case highlights the effectiveness of SCTG combined with CAF in managing complex recession defects and emphasizes the importance of accurate diagnosis and meticulous surgical technique for predictable clinical outcomes.
