The Comparison of Different Root Coverage Techniques Using the Anatomical Recession Area Approach

The goal of this clinical trial is to compare the effectiveness of two treatments for gingival recession. The main questions it aims to answer are: Which treatment method, Coronally Positioned Flap with Connective Tissue Graft or Modified Coronally Advanced Tunnel with connective tissue graft, is more effective in treating gum recession? How does the Anatomical Recession Rate, a new measurement technique, help in evaluating the success of these treatments? The patients will be treated with coronally advanced flap or modified coronally advanced tunnel + connective tissue graft to see which method is more effective in reducing gum recession, as measured by using anatomical recession rate.
