V-CAF Technique for Miller Class III Gingival Recession

The purpose of this clinical trial is to evaluate the effectiveness of a modified surgical technique called the vertically coronally advanced flap (V-CAF) combined with a connective tissue graft and tissue regeneration for treating gingival recession. For more severe cases (Miller Class III), the study investigates the relationship between the pre-operative Coronally Advanced Flap Difficulty Score (CAFDS) and post-operative outcomes, such as the root coverage rate and interdental papilla height. Participants will undergo the assigned surgical treatment and will be followed up at 3, 6, and 12 months to assess healing and tissue stability.
