Vertically Coronally Advanced Flap Versus Coronally Advanced Flap for Miller Class I Gingival Recession

This randomized controlled clinical trial aims to compare the clinical effectiveness of the Vertically Coronally Advanced Flap (VCAF) and the Coronally Advanced Flap (CAF), both combined with connective tissue graft (CTG) and enamel matrix derivative (EMD), for the treatment of Miller Class I gingival recession. Twenty-six Miller Class I gingival recession defects will be randomly assigned in a 1:1 ratio to either the VCAF + CTG + EMD group or the CAF + CTG + EMD group. Clinical outcomes, including mean root coverage, complete root coverage, recession depth, recession width, probing depth, clinical attachment level, keratinized tissue width, gingival thickness, vestibular depth, and esthetic outcomes, will be assessed at baseline and throughout a 6-month follow-up period. Three-dimensional digital models obtained from an intraoral scanner will also be used to evaluate soft tissue changes following treatment. The study is designed to determine whether the VCAF technique provides superior clinical and esthetic outcomes compared with the conventional CAF technique.
